Kaderka R. 2020. Neischnocolus iquitos, a new species from Peru (Araneae: Theraphosidae: Theraphosinae). Revista peruana de biología 27(4): 441 - 450 (Noviembre 2020). doi: http://dx.doi.org/10.15381/rpb.v27i4.19198
Neischnocolus iquitos sp. nov. from Loreto region, Peru, is described, diagnosed and figured. Males of N. iquitos sp. nov. differ from all known congeners in the presence of two retrolateral processes on palpal tibia, in combination with the presence of a retrolateral keel on embolus and the absence of granulation or microspikes on embolus or tegulum. Females of N. iquitos sp. nov. differ from all known Neischnocolus females in the morphology of the genitalia consisting of a lower sclerotized part with two short, separate seminal receptacles, and an upper part, which is transparent and notched.
Opisany novy druh Neischnocolus iquitos.

Bertani, R. & Almeida, M. Q. (2021). Yanomamius n. gen., a new genus of tarantula from Brazilian and Venezuelan Amazon (Araneae, Theraphosidae), with description of three new species. Zootaxa 4933(3): 324-340.
The new genus Yanomamius n. gen. from Brazilian and Venezuelan Amazon is described, with three new species from Brazil: Y. franciscoi n. sp. (type species), Y. raonii n. sp., and Y. neblina n. sp. The enigmatic Venezuelan species described as Holothele waikoshiemi Bertani & Araújo, 2006 and presently included in Guyruita Guadanucci et al. (2007) is transferred to the new genus, making the new combination Y. waikoshiemi (Bertani & Araújo, 2006) n. comb. Yanomamius n. gen. is closely related with the schismatotheline genera Schismatothele Karsch, 1879 and Euthycaelus Simon, 1889 sharing as probable synapomorphies a group of short spines on the retrolateral distal tibia of male palp and the shape of bulb. They differ by the position of the spines in a compact group instead of in rows and by a tapering embolus. Females differ from Schismatothele and Euthycaelus by the spermathecae weakly sclerotized. A series of recent phylogenies based on molecular data suggested a close relationship between schimatothelines and psalmopoeines. The male tibia I of Yanomamius n. gen. species have a series of ridges or a single protuberance behind the tibial apophyses that resemble those of psalmopoeines and strengthen the idea of close relationship of the two subfamilies.
Opis noveho rodu Yanomamius s druhmi franciscoi, raonii, neblina. Do noveho rodu sa presunul aj druh Guyruita waikoshiemi.

Dupérré, N. & Tapia, E. (2021). The endless search for type specimens; illustrations of eleven spider (Araneae, Mygalomorphae) species described by Eugène Simon. Zootaxa 4951(2): 259-282. doi:10.11646/zootaxa.4951.2.3
French arachnologist Eugène Simon is considered one of the most prolific arachnologists of all time. Unfortunately, Simon often provided very short descriptions with or without illustrations which makes recognition of his species difficult for subsequent taxonomists. Eugène Simon described 3,789 species of spiders in his career, and most of his type specimens are assumed to be held in the Muséum National d’Histoire Naturelle in Paris, France. We present here the images of eleven Mygalomorphae species described by E. Simon that were never thoroughly illustrated: Cyrtaucheniidae: Fufius albovittatus, F. atramentarius, F. ecuadorensis;Dipluridae: Masteria cavicola, Diplura riveti, and Linothele soricina;Halonoproctidae: Ummidiaasperula;Idiopidae: Idiops argus, I. fulvipes, I. opifex and Theraphosidae: Heterothele caudicula.

Fukushima, C. S., Cardoso, P. & Bertani, R. (2020). Description of the male of the Critically Endangered tarantula Typhochlaena curumim Bertani, 2012 (Araneae, Theraphosidae), with comments on tarantula trade and conservation. ZooKeys 938: 125-136. doi:10.3897/zookeys.938.51442
The genus Typhochlaena C.L. Koch, 1850 consists of five small size arboreal tarantula species with remarkable colored abdominal patterns and a very restricted geographic range in Brazil. Here, we describe the male of Typhochlaena curumim Bertani, 2012, which was collected in an area of Brazilian Atlantic Rainforest. The new record extends the northern limit of the geographic range for both the genus and species. As Typhochlaena spp. are now especially popular and requested in the pet market, and because T. curumim is classified as Critically Endangered, we discuss the impacts of the international trade and other challenges on conservation of the genus.

Mori, A. & Bertani, R. (2020). Revision and cladistic analysis of Psalistops Simon, 1889, Trichopelma Simon, 1888 and Cyrtogrammomma Pocock, 1895 (Araneae: Theraphosidae) based on a cladistic analysis of relationships of Theraphosidae, Barychelidae and Paratropididae. Zootaxa 4873(1): 1-132. doi:10.11646/zootaxa.4873.1.1

The genera Psalistops Simon, 1889, Trichopelma, Simon, 1888 and Cyrtogrammomma Pocock, 1895 are revised and included in cladistics analyses including almost all species of these genera. In order to test previous morphological hypotheses on the relationships of Barychelidae, Paratropididae and Theraphosidae and because of the controversial taxonomic position of Psalistops and Trichopelma, a set of terminal taxa representing all subfamilies of Paratropididae (Paratropidinae, Glabropelmatinae), Barychelidae (Barychelinae, Sasoninae, Trichopelmatinae) and most theraphosid subfamilies were included, as well as a diplurid, a nemesiid, and a pycnothelid, the later used to root the cladogram. The matrix with 66 terminal taxa, 2 continuous and 93 discrete characters was analysed with TNT 1.5. We found that Trichopelmatinae is not a monophyletic group, and Psalistops is transferred to Theraphosidae, as well as the barychelid genus Cyrtogrammomma and the paratropidid genus Melloina Brignoli. Cyrtogrammomma was retrieved as the sister group of Trichopelma, and Melloina as the sister group of Holothele Karsch. Psalistops was retrieved as the sister group of Reichlingia Rudloff, and the clade with these two genera is the most basal in Theraphosidae. Barychelidae was found to be monophyletic and the sister group of Theraphosidae. Paratropididae was retrieved as the sister group of Barychelidae + Theraphosidae. The relationship and possible synapomorphies of the three families are herein discussed. This is the first time since Raven (1985) that representatives of all barychelid (Barychelinae, Sasoninae, Trichopelmatinae), paratropidid (Paratropidinae, Glabropelmatinae) and most theraphosid subfamilies have been included in a morphological cladistic analysis. Psalistops comprises two species, P. melanopygius Simon, 1889 (type species) and P. colombianus sp. nov. Psalistops montigena Simon, 1889, P. tigrinus Simon, 1889 and P. zonatus Simon, 1889 are synonymized with P. melanopygius Simon, 1889. Psalistops fulvus Bryant, 1948, P. hispaniolensis Wunderlich, 1988 (fossil), P. maculosus Bryant, 1948, P. venadensis Valerio, 1986 and P. steini (Simon, 1889) are transferred to Trichopelma. Psalistops gasci Maréchal, 1996 is transferred to Hapalopus Ausserer (Theraphosidae); P. opifex (Simon, 1889) and P. solitarius (Simon, 1889) are transferred to Schismatothele Karsch, 1879 (Theraphosidae). Schismatothele solitarius (Simon, 1889) n. comb. is synonymized with Schismatothele lineata Karsch, 1879, n. syn. Psalistops nigrifemuratus Mello-Leitão, 1939 is probably a nemesiid or pycnothelid, and herein considered as nomen dubium in Pycnothelidae. Trichopelma comprises 22 species: Trichopelma nitidum Simon, 1888 (type species), T. coenobita (Simon, 1889), T. steini (Simon, 1889), T. affine (Simon, 1892), T. cubanum (Simon, 1903), T. maculatum (Banks, 1906), T. zebra (Petrunkevitch, 1925), T. banksia Özdikmen & Demir, 2012, T. insulanum (Petrunkevitch, 1926), T. fulvus (Bryant, 1948) n. comb., T. laselva Valerio, 1986, T. venadensis (Valerio, 1986) n. comb., T. huffi sp. nov., T. gabrieli sp. nov., T. tostoi sp. nov., T. goloboffi sp. nov., T. juventud sp. nov., T. laurae sp. nov., T.bimini sp. nov., T. loui sp. nov., T. platnicki sp. nov., and T. hispaniolensis Wunderlich, 1988 n. comb. (fossil). Trichopelma maculosus (Bryant, 1948) n. comb. is synonymized with P. fulvus Bryant, 1948; T. corozalis (Petrunkevitch, 1929) is synonymized with T. insulanum (Petrunkevitch, 1926). Trichopelma astutum Simon, 1889 is transferred to Euthycaelus Simon, 1889, and T. maddeni Esposito & Agnarsson, 2014 to Holothele Karsch, 1879 (Theraphosidae). Trichopelma flavicomum Simon, 1891 is transferred to Neodiplothele (Barychelidae, Sasoninae). The species T. illetabile Simon, 1888, T. spinosum (Franganillo, 1926), T. scopulatum (Fischel, 1927) and T. eucubanum Özdikmen & Demir, 2012 are considered as nomina dubia. Cyrtogrammomma comprises two species: C. monticola Pocock, 1895 (type species) and C. raveni sp. nov.

Gabriel, R., Sherwood, D. & Longhorn, S. J. (2020). The revised taxonomic placement of the genus Acentropelma Pocock, 1901 and restoration of the genus Pseudoschizopelma Smith, 1995 (Aranei: Theraphosidae). Arthropoda Selecta 29(4): 453-466. doi:10.15298/arthsel.29.4.07
The genus Acentropelma Pocock, 1901 is redefined and the type species, A. spinulosum F.O. Pickard-Cambridge, 1897 is redescribed. Pseudoschizopelma Smith, 1995 gen.rest. is restored to house Acentropelma macropus (Ausserer, 1875) creating the restored combination Pseudoschizopelma macropus comb.rest. Acentropelma sorkini Smith, 1995 syn.n. is considered a junior synonym of P. macropus based on indistinguishable palpal bulb, tibial apophysis and spermathecal morphology. The paratype female of former A. sorkini, originally designated and described by Smith [1995] is found to be an immature Brachypelma Simon, 1891 – possibly Brachypelma kahlenbergi Rudloff, 2008. Additional morphological features for A. gutzkei are included to complement the original description by Reichling [1997], and its placement discussed.

Borges, L. M., Paladini, A. & Bertani, R. (2021). Two new species of Eupalaestrus Pocock, 1901 (Araneae: Theraphosidae) from southern Brazil and northeastern Argentina. Journal of Natural History 55(13-14): 889-908. doi:10.1080/00222933.2021.1925767
After a morphological analysis of several tarantula specimens of the genus Eupalaestrus, including recently collected specimens from previously unrecorded localities, we herein describe two new species. They differ from congeners by the presence of a large area with spiniform setae between the coxae IV. They differ from each other in general size and in the thickening of the tibia and metatarsus IV. Eupalaestrus crassimetatarsis sp. nov. is distributed in the Brazilian States of Paraná, Rio Grande do Sul and Santa Catarina, and in Misiones Province in Argentina. Eupalaestrus roccoi sp. nov. is distributed in the Brazilian state of Rio Grande do Sul. These natural grasslands are under threat from rapidly encroaching arable and livestock farming.

A new species of Cymbiapophysa Gabriel & Sherwood, 2020, C. magna sp. nov. is described from Colombia. Proshapalopus marimbai Perafán & Valencia-Cuéllar, 2018 is transferred to Cymbiapophysa from Proshapalopus Mello-Leitão, 1923, based on male palpal bulb and tibial apophysis morphology, female spermathecal morphology, comparative labial cuspule counts in both sexes, and biogeography, creating the new combination Cymbiapophysa marimbai comb. nov. Aspects of some structures of the male palpal bulb are also discussed.

Sherwood, D., Gabriel, R., Kaderka, R., Lucas, S. M. & Brescovit, A. D. (2021c). Stabilizing a chaotic taxonomy: redescription and redefinition of the genera Lasiodorides Schmidt & Bischoff, 1997 and Thrixopelma Schmidt, 1994 (Araneae: Theraphosidae). Arachnology 18(8): 893-917. 
The genera Lasiodorides Schmidt & Bischoff, 1997 and Thrixopelma Schmidt, 1994 are preliminarily revised, and their taxonomy stabilized. Both sexes of Lasiodorides polycuspulatus Schmidt & Bischoff, 1997, and the male of Lasiodorides striatus (Schmidt & Antonelli, 1996) are redescribed, and the genus Lasiodorides is rediagnosed. Lasiodorides rolinae Tesmoingt, 1999 is proposed as a junior synonym of L. polycuspulatus syn. nov., based on colouration and spermathecal morphology. Lasiodorides remotus Schmidt, 2007 is proposed as a junior synonym of L. polycuspulatus syn. nov., based on spermathecal morphology. Thrixopelma aymara (Chamberlin, 1916) and Thrixopelma lagunas Schmidt & Rudloff, 2010 are redescribed. Thrixopelma ockerti Schmidt, 1994 is illustrated from the syntype series and redescribed based on a non-type female from Iquitos, Peru, held in the collections of the Museo de Historia Natural, Universidad Nacional Mayor de San Marcos, Lima, Peru. Thrixopelma longicolli (Schmidt, 2003) comb. nov. is newly transferred from Lasiodorides to Thrixopelma based on palpal bulb morphology, and the holotype male is redescribed. The inherent problems of the paratype exuviae of this taxon are also discussed. Thrixopelma peruvianum (Schmidt, 2007) comb. nov. is newly transferred from Euathlus Ausserer, 1875 following examination of the holotype female exuvia and a conspecific non-type female exuvia. Thrixopelma cyaneolum Schmidt, Friebolin & Friebolin, 2005 is discussed ad illustrated from the syntype female exuviae. Thrixopelma pruriens Schmidt, 1998 is discussed and illustrated from the holotype female exuvia, and the problematic non-type material discussed. Finally, we argue that future designation of exuviae as type specimens of novel theraphosid spiders should be considered an unacceptable practice in arachnology.

Kaderka, R., Ferretti, N., Hüsser, M., Lüddecke, T. & West, R. (2021). Antikuna, a new genus with seven new species from Peru (Araneae: Theraphosidae: Theraphosinae) and the highest altitude record for the family. Journal of Natural History 55(21-22): 1335-1402. doi:10.1080/00222933.2021.1936680
Antikuna, a new genus from Peruvian Andes, was proposed, diagnosed and described, to include seven new species: Antikuna cernickai sp. nov., A. cimrmani sp. nov., A. cyanofemur sp. nov., A. majkusi sp. nov., A. sapallanga sp. nov., A. urayrumi sp. nov. and A. valladaresi sp. nov. Antikuna gen. nov. is characterised by having the type III urticating setae concentrated in one dorsal patch, ventral side of maxillae with short spiniform setae in apical half, the male bulb carrying four keels, prolateral superior, prolateral inferior, apical and subapical keel termi-nating in a short tooth, and the female spermathecae consisting of two separate divergent seminal receptacles, carrying one or more ventral keels, and dorsally with distinct oval apical lobe, which is narrower than the receptacle neck. In the males of Antikuna gen. nov. the flexion of metatarsi I is between both branches of tibial apophyses and prolateral cymbial lobe is distinctly larger than retrolateral one. Antikuna gen. nov. inhabits altitudes above 3,800 m a.s.l. and A. valladaresi sp. nov. was found in the altitude of 4,689 m a.s.l. representing a new highest altitude record for the family Theraphosidae.

Sivayyapram, V., Kunsete, C., Songsangchote, C., Thanoosing, C., Traiyasut, P. & Warrit, N. (2020). Two new species of the Southeast Asian dwarf tarantula genus Phlogiellus Pocock, 1887 (Theraphosidae, Selenocosmiinae) and a discussion on the taxonomic problem of the genus. Zootaxa 4859(4): 487-506, 4869(4): 599-600. , 10.11646/zootaxa.4869.4.7 doi:10.11646/zootaxa.4859.4.2
Phlogiellus is one of the least studied theraphosid genera; there is only one recent revision on the genus. However, the “revision” only provided several taxonomic problems in the genus by giving unclear diagnostic characters of the genus and its species, using third party information in their descriptions and many of their examined specimens of are inaccessible. Here, we discuss the taxonomic problems of the genus, and provide a new genus description and diagnostic characters of Phlogiellus by combining information from previous studies with our examinations. Variation within species of previously diagnostic characters renders them of little value. In addition, two new Phlogiellus species from Myanmar and the Philippines are described and diagnosed here.

Galleti-Lima, A., Indicatti, R. P. & Guadanucci, J. P. L. (2021). Catumiri Guadanucci, 2004: new diagnosis, first description of the female of C. petropolium Guadanucci, 2004, and new records of the genus from Brazil and Uruguay (Theraphosidae: Ischnocolinae). Arachnology 18(8): 844-848. doi:10.13156/arac.2021.18.8.844 
The ischnocoline genus Catumiri Guadanucci, 2004 comprises four species distributed in Argentina, Brazil, Chile, and Uruguay.

Candia-Ramírez, D. T. & Francke, O. F. (2021). Another stripe on the tiger makes no difference? Unexpected diversity in the widespread tiger tarantula Davus pentaloris (Araneae: Theraphosidae: Theraphosinae). Zoological Journal of the Linnean Society 192(1): 75-104. doi:10.1093/zoolinnean/zlaa107
Integrative taxonomy is relevant for the discovery and delimitation of cryptic species by incorporating different sources of evidence to construct rigorous species hypotheses. The genus Davus was recently revised and it was found that Davus pentaloris presents high morphological variation across its widespread distribution. However, tarantulas usually present low dispersal capabilities that occasionally result in local endemism. In order to evaluate species boundaries within this taxon, we examine the morphological variation and, additionally, employ four strategies based on mtDNA data (COI): two distance-based [automatic barcode gap discovery (ABGD) and Neighbor-Joining (NJ)] and two tree-based methods [general mixed Yule coalescent (GMYC) and Bayesian Poisson tree process (bPTP)]. Available morphological evidence recovers 13 putative morphospecies, but the different methods based on molecular data recover a variable number of candidate species (16–18). Based on the congruence across all analyses and the available morphological data, we recognize 13 clearly diagnosable species, 12 of them new to science. We conclude that the underestimation of the diversity in D. pentaloris was mainly caused by deficient practices in taxonomy, rather than by the presence of cryptic diversity. Although COI is a functional barcoding marker and it gives reliable results in our study, we recommend combining multiple sources of evidence and strategies to construct better species delimitation hypotheses.

Bamboo plays an important role in the animal world, including providing a nutritious food source, shelter, and habitat. Inside of bamboo culm, we discovered a new genus of tarantula, which we describe here as Taksinus gen. nov. (♂♀). Specimens of this new tarantula were collected from Mae Tho, Mueang Tak district, Tak province, in Thailand, making it geographically distant from any other arboreal genera. Genital morphology was used to diagnose its genus, which is supported by distributional data, natural history, morphological characters, and photographic illustrations of the male and female. Diagnosis of the new genus was determined by distinguishing its different characters from those of other arboreal theraphosid spiders distributed throughout Southeast Asia. This tarantula’s specialization is that it lives in the stalks of the Asian bamboo Gigantochloa sp.

Korba, Jan & Opatova, Vera & Calatayud-Mascarell, Arnau & Enguídanos, Alba & Bellvert Bantí, Adrià & Arnedo, Miquel. (2022). Systematics and phylogeography of western Mediterranean tarantulas (Araneae: Theraphosidae). Zoological Journal of the Linnean Society. 10.1093/zoolinnean/zlac042.

Theraphosidae is the most diversified family of mygalomorph spiders, commonly known as tarantulas. Two genera inhabit the Mediterranean region: Chaetopelma in the east and Ischnocolus mostly in the western part of the Basin. Their phylogenetic position and the validity of some Ischnocolus species remain unclear. We implemented a multilocus target approach to shed new light on the position of both genera and further integrated molecular data with additional lines of evidence (morphology and ecology) to explore species boundaries in western Mediterranean Ischnocolus. Our results reveal that Ischnocolus and Chaetopelma are not closely related. Chaetopelma formed a clade with the African subfamily Eumenophorinae and Ischnocolus was recovered in a clade comprising all remaining theraphosids. The western Mediterranean Ischnocolus comprises two deeply divergent clades that separated during the Early Miocene and differ in both morphology and lifestyle. We found molecular, morphological and ecological evidence to restore the name Ischnocolus mogadorensis and revalidate this species. We also uncovered distinct allopatric lineages in Ischnocolus elongatus. However, the lack of males, the uniform morphology of females and low within-clade support hampered the assessment of their status and boundaries. Finally, our data support that I. elongatus should be considered a senior synonym of Ischnocolus hancocki and Harpactirella insidiosa.

Cifuentes, Y. & Bertani, R. (2022). Taxonomic revision and cladistic analysis of the tarantula genera Tapinauchenius Ausserer, 1871, Psalmopoeus Pocock, 1985, and Amazonius n. gen. (Theraphosidae, Psalmopoeinae). Zootaxa 5101(1): 1-123. doi:10.11646/zootaxa.5101.1.1
The genera Psalmopoeus Pocock, 1895, Tapinauchenius Ausserer, 1871 and Pseudoclamoris Hüsser, 2018 are revised and cladistics analyses carried out including most species of these genera. In order to test the monophyly of Aviculariinae and Psalmopoeinae, species of all genera in these two subfamilies were included, as well as of Harpactirinae, Selenocosmiinae, Theraphosinae, Stromatopelmatinae, Ischnocolinae, Schismatothelinae, Poecilotherinae, and a barychelid was used to root the cladogram. The matrix with 50 terminal taxa, 1 continuous and 85 discrete characters was analysed with TNT 1.5. The results show a monophyletic Psalmopoeinae as sister group of Aviculariinae. Psalmopoeus comprises 9 species: Psalmopoeus cambridgei Pocock, 1895 (type species), Psalmopoeus ecclesiasticus Pocock, 1903, Psalmopoeus emeraldus Pocock, 1903, Psalmopoeus irminia Saager, 1994, Psalmopoeus langenbucheri Schmidt, Bullmer & Thierer- Lutz, 2006, Psalmopoeus plantaris Pocock, 1903, Psalmopoeus pulcher Petrunkevitch, 1925, Psalmopoeus reduncus (Karsch, 1880), and Psalmopoeus victori Mendoza, 2014. Psalmopoeus intermedius Chamberlin, 1940 is considered a junior synonym of P. reduncus. Psalmopoeus copanensis Gabriel & Sherwood, 2020, P. sandersoni Gabriel & Sherwood, 2020 and P. petenensis Gabriel & Sherwood, 2020 are considered junior synonyms of P. victori. Psalmopoeus maya Witt, 1996 is considered nomen nudum. Tapinauchenius comprises 8 species: Tapinauchenius plumipes (C. L. Koch, 1842) (type species), Tapinauchenius sanctivincenti (Walckenaer, 1837), Tapinauchenius latipes L. Koch, 1875, Tapinauchenius brunneus Schmidt, 1995, Tapinauchenius cupreus Schmidt & Bauer, 1996, Tapinauchenius polybotes Hüsser, 2018, Tapinauchenius rasti Hüsser, 2018, and T. gretae n. sp. The female of T. brunneus is described for first time. Tapinauchenius violaceus (Mello-Leitão, 1930), T. purpureus Schmidt, 1995, T. concolor (Caporiaccco, 1947), andT. gigas Caporiacco, 1954 are considered junior synonyms of T. plumipes. With the synonymy of T. gigas (type species of Pseudoclamoris Hüsser, 2018), it was necessary to describe a new genus for the two species formerly included in it. Thus, the new genus Amazonius n. gen. is erected to include A. elenae (Schmidt, 1994) n. comb., A. burgessi (Hüsser, 2018) n. comb. as well as two new species A. giovaninii n. gen. n. sp. and A. germani n. gen. n. sp. A discussion on the relationship of Psalmopoeinae and Aviculariinae and maps with the distributions of all species are provided.

The genus Cyrtogrammomma Pocock, 1895 was proposed based on specimen samples from Monte Roraima, Guyana, and allocated in the family Barychelidae. However, the most recent cladistic analysis transferred Cyrtogrammomma to Theraphosidae. Herein, we amended the diagnosis and description of C. monticola, providing a redescription of the male, and new illustrations, including the description of a new cuticular structure consisting of thick and stiff setae on dorsal metatarsi I and II of females. Moreover, we diagnose, describe and illustrate a new species of Cyrtogrammomma from northeastern Brazil: C. frevo sp. nov. In addition, we provide an identification key, new distribution records of the genus in the states of Alagoas, Bahia, Pará, and Pernambuco, in Brazil, and the first record for the genus in caves.

The tarantula genus Tmesiphantes Simon, 1892 includes 20 valid species distributed in Argentina and Brazil. These spiders are distinguished from other Theraphosinae genera by the presence of an incrassate femur III, more evident in males, urticating hair types III and IV on the abdominal dorsum, few cuspules on the labium (0 to 30), maxillae with a maximum of 200 cuspules and sternum rounded. From recent examination of material from Peru, we discovered specimens that share all the morphological characters of Tmesiphantes, but did not fi t with any known species. In the present study T. intiyaykuy sp. nov. is diagnosed, described, and illustrated. This new species resembles T. caymmii in the circular patch with stiff setae on midventral abdomen but can be distinguished by the shape of the palpal bulb and spermathecae. Also, we performed a phylogenetic analysis using morphological characters to infer the taxonomic placement of the new species. The analysis included 26 terminal species and 36 characters. Representatives of Tmesiphantes formed a monophyletic group and T. intiyaykuy sp. nov. is close related with T. caymmii. A dichotomous identifi cation key and a geographic distribution map were constructed for recognized species of Tmesiphantes.

Abstract. Salamanes JJDP, Santos JMJ, Austria ES, Villancio GGS. 2022. Short Communication: A new species of tarantula of the genus Orphnaecus Simon, 1892 (Araneae: Theraphosidae) from the Province of Dinagat Islands, Philippines. Biodiversitas 23: 4283-4288. Orphnaecus adamsoni sp. nov., a new species of tarantula of the genus Orphnaecus Simon, 1892 is described and illustrated based on the specimens collected from the Province of Dinagat Islands, Philippines. It closely resembles O. kwebaburdeos (Barrion-Dupo, Barrion & Rasalan, 2015). However, it can be easily distinguished by having a rounded carapace, shorter leg segments, more clavate-paddle shaped maxillary lyra, and a different habitat. This mygalomorph spider discovery constitutes the fifth species described for Orphnaecus and the fourth record in the Philippines.
