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.

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.
