Schwerdt, Leonela & Villalobos, Ana & Pérez-Miles, Fernando. (2017). Spiders as potential bioindicators of mountain grasslands health: the Argentine tarantula Grammostola vachoni (Araneae, Theraphosidae). Wildlife Research.
Abstract Context. Bioindicators are used for conservation prioritization by means of spatial comparisons of a site value, or monitoring of ecosystem recovery or response to management. Spiders are characterized by their selection of quality habitats and guild responses to environmental change. However, they have only occasionally been used as bioindicators. Grammostola vachoni is an endemic tarantula that only occurs in the grasslands of the mountainous system in central Argentina and it is included in the Red List of the IUCN as Vulnerable. Aims. In this study, we performed a characterization of the microhabitat of G. vachoni at sites with different disturbance regimes and we analyzed the potential use of this species as a bioindicator of mountain grassland health. Methods. We determined the microhabitat characteristics around their refuges by mean of the soil parameters, as well as the composition and structure of vegetation and amount of refuge available. Key results. We found significant differences in the number of individuals and the percentage of occupation between sites. No significant differences were recorded in the soil characteristics and occupation of G. vachoni but we found that the composition of vegetation, and the heterogeneity and diversity of plants are influenced by different disturbance regimes, altering the distribution of spiders. Conclusions. Our results are consistent with those of other studies where the spiders have proved to be good bioindicators of different disturbances and we propose for the first time a Theraphosidae species for evaluating the state or health of a natural grassland. Implications. The information reported in this study is very important to provide data for a future re-categorization of G. vachoni for the Red List of IUCN. Also, we add new component of ecosystems for to use as indicator, open up the possibility for new research for the same and other species of a grasslands of the mountainous system. Spiders as potential bioindicators of mountain grasslands health: the Argentine tarantula Grammostola vachoni (Araneae, Theraphosidae).

Tim Lüddecke, Henrik Krehenwinkel, Gregory Canning, Frank Glaw, Stuart J. Longhorn, René Tänzler, Ingo Wendt, Miguel Vences, Discovering the silk road: Nuclear and mitochondrial sequence data resolve the phylogenetic relationships among theraphosid spider subfamilies, In Molecular Phylogenetics and Evolution, Volume 119, 2018, Pages 63-70, ISSN 1055-7903, https://doi.org/10.1016/j.ympev.2017.10.015.
The mygalomorph spiders in the family Theraphosidae, also known as “tarantulas”, are one of the most popular and diverse groups of arachnids, but their evolutionary history remains poorly understood because morphological analyses have only provided mostly controversial results, and a broad molecular perspective has been lacking until now. In this study we provide a preliminary molecular phylogenetic hypothesis of relationships among theraphosid subfamilies, based on 3.5 kbp of three nuclear and three mitochondrial markers, for 52 taxa representing 10 of the 11 commonly accepted subfamilies. Our analysis confirms the monophyly of the Theraphosidae and of most recognized theraphosid subfamilies, supports the validity of the Stromatopelminae and Poecilotheriinae, and indicates paraphyly of the Schismatothelinae. The placement of representatives of Schismatothelinae also indicates possible non-monophyly of Aviculariinae and supports the distinction of the previously contentious subfamily Psalmopoeinae. Major clades typically corresponded to taxa occurring in the same biogeographic region, with two of them each occurring in Africa, South America and Asia. Because relationships among these major clades were poorly supported, more extensive molecular data sets are required to test the hypothesis of independent colonization and multiple dispersal events among these continents.

Turner, S. P., Longhorn, S. J., Hamilton, C. A., Gabriel, R., Pérez-Miles, F. & Vogler, A. P. (2018). Re-evaluating conservation priorities of New World tarantulas (Araneae: Theraphosidae) in a molecular framework indicates nonmonophyly of the genera, Aphonopelma and Brachypelma. Systematics and Biodiversity 16(1): 89-107.
We present a mtDNA gene tree of tarantula spiders (Araneae: Mygalomorphae: Theraphosidae) based on the mitochondrial 16S-tRNA (leu)-ND1 gene region as a promising initial molecular hypothesis to clarify the taxonomy of the largest subfamily, Theraphosinae. Many species of this New World subfamily are traded widely as exotic pets, yet few scientific studies on them exist, and the robustness of many supposed taxonomic groupings is debatable. Yet the validity of taxon names and knowledge of their distinctiveness is vital for trade regulation, most notably for the Neotropical genus Brachypelma Simon 1891, which is listed under CITES (Appendix II, see online supplemental material, which is available from the article’s Taylor & Francis Online page at https://doi.org/10.1080/14772000.2017.1346719). The use of molecular markers for tarantula taxonomy has been limited until recently, with most previous studies relying on morphological methods. Our findings, from newly collected molecular data, have several nomenclatural implications, suggesting a need for a rigorous overhaul of Theraphosinae classification at multiple hierarchical levels. Here, we take steps toward a revised classification, favouring division of Theraphosinae into three tribes: the Theraphosini trib. nov., the Hapalopini trib. nov., and the Grammostolini trib. nov. We also make conservation recommendations for two non-monophyletic genera. Firstly, we recover Aphonopelma Pocock 1901 as polyphyletic, finding that the large radiation into the USA and Mexico is taxonomically distinct from at least three other lineages distributed throughout Central America, one of which includes the type species of the genus. Secondly, and importantly for conservation, we find diphyly in the CITES listed genus Brachypelma Simon 1891, where our data strongly favour a division into two distinct smaller genera. We consider only the lineage with endemics in the Pacific coastal zone of Mexico to be of conservation concern. Finally, we also make suggestions on the future direction of revisionary research for the Theraphosidae as a whole.

Mendoza, J. I. & Francke, O. F. (2018). Five new cave-dwelling species of Hemirrhagus Simon 1903 (Araneae, Theraphosidae, Theraphosinae), with notes on the generic distribution and novel morphological features. Zootaxa 4407(4): 451-482.
The suborder Mygalomorphae is generally poorly represented in the cave faunas of the world. The genus Hemirrhagus is endemic to Mexico and has 22 described species. It is the only one with epigean, troglophile and troglobitic species. Lack of urticating setae, loss of eye pigmentation and ocular reduction are interpreted as evolutionary reversals related to their troglobitic habits. From five troglobitic species in the genus, only the male of Hemirrhagus stygius is known. Five new troglobitic species are described with both sexes: Hemirrhagus akheronteus sp. nov., Hemirrhagus billsteelei sp. nov., Hemirrhaugus diablo sp. nov., Hemirrhagus kalebi sp. nov. and Hemirrhagus sprousei sp. nov. The female of Hemirrhagus chilango is described for the first time. Hemirrhagus akheronteus sp. nov. has a group of spinose setae on the opisthosoma; this setal modification was never reported in any other theraphosid spiders. Females of Hemirrhagus kalebi sp. nov. and Hemirrhagus sprousei sp. nov. lay fixed hammock egg sacs, which is an unusual behavior among species in Theraphosinae. Two stridulating setae previously reported only in epigean species are present on some of the new troglobites.

As the species Haploclastus devamatha Prasanth & Jose, 2014 is indistinguishable from Thrigmopoeus psychedelicus Sanap & Mirza, 2014, the latter is herein considered junior synonym of the former. Occurrence of polychromatism in H. devamatha is noted, and two distinct colour morphs of the species are recognised, a pink form and a blue form. The natural history and conservation of the species are discussed and its known distribution is updated.

Arthur Galleti Lima & José Paulo Leite Guadanucci. 2018 Morphology of setae on the coxae and trochanters of theraphosine spiders (Mygalomorphae: Theraphosidae) Journal of Arachnology 46(2):214-225.
Abstract. Mygalomorphae spiders have several cuticular structures, such as stridulating, sensory and urticating setae, which offer great potential for phylogenetic studies. Spiders of the subfamily Theraphosinae have stridulating setae that aid in group taxonomy, having been found in numerous genera including: Acanthoscurria Ausserer, 1871, Aguapanela Perafa´ n, Cifuentes & Estrada-Gomez, 2015, Citharacanthus Pocock, 1901, Cyrtopholis Simon, 1892, Grammostola Simon, 1892, Hemirrhagus Simon, 1903, Lasiodora C. L. Koch, 1850, Longilyra Gabriel, 2014, Pamphobeteus Pocock, 1901, Phormictopus Pocock, 1901 and Theraphosa Thorell, 1870. Some distinct bristle-like setae were examined using scanning electron microscopy with the following objectives: (1) to sample and describe the diversity of setae on the coxae and trochanters of representatives of the subfamily Theraphosinae; and (2) to code morphological characters useful for phylogenetics. We used a previously published phylogenetic matrix, with modifications to those characters that scored stridulatory setae, and analyzed these data using parsimony with implied weighting. Setae of the same type were found in Acanthoscurria, Brachypelma Simon, 1891, Cyrtopholis, Phormictopus and Theraphosa (claviform stridulating setae). A second type, which we name velvet stridulating setae, emerged as an autapomorphy of the genus Lasiodora, and spiniform stridulating setae were recovered as an autapomorphy of the genus Pamphobeteus. Some other setae similar to those of Lasiodora, named plumose stridulating setae, were found in Nhandu Lucas, 1983, Proshapalopus Mello-Leit˜ao, 1923, Pterinopelma Pocock, 1901 and Vitalius Lucas, Silva & Bertani, 1993.

Captive breeding of Pamphobeteus ultramarinus proved difficult since the Ecuadorian highland species has been kept in captivity and was scientifically described in 1995. In this article the author describes natural history data for the species and provides information for increased understanding of its complex ecology. Information regarding husbandry and successful breeding are given. Altogether the species is considered to be ideally suited for beginners as well as for keeping in captivity due to its peaceful and undemanding nature. Comments on the genus Pamphobeteus are given, such as the possibility of dividing the speciesrich genus roughly into groups that comply with the appearance of nymph stages.

Coremiocnemis hoggi is a attractive theraphosid spider which inhabits a restricted area within the highlands of Malaysia. The habitat of the spiders is determined by a humid climate with rather cool temperatures to which Coremiocnemis hoggi has adapted with its life cycle. Due to the small distribution illegal collecting and trafficking for the pet trade is a threat to the population of Coremicnemis hoggi in its habitat and a decline of these spiders has already been observed by locals. To avoid more illegal trafficking and since Coremiocnemis hoggi is difficult to keep in captivity because of its special needs concerning the climatic conditions it should be avoided to purchase specimen.

Gargiulo, F. de F., Brescovit, A. D. & Lucas, S. M. (2018). Umbyquyra gen. nov., a new tarantula spider genus from the Neotropical region (Araneae, Mygalomorphae, Theraphosidae), with a description of eight new species. European Journal of Taxonomy 457: 1-50. 
Umbyquyra gen. nov., a new Theraphosinae genus with stridulatory bristles on the palpal trocanther of pedipalp trochanter and first leg, is proposed. The genus differs from the other genera with stridulatory bristles on the same segments, Acanthoscurria Ausserer, 1871, Cyrtopholis Simon, 1892, Longilyra Gabriel, 2014 and Nesipelma Schmidt & Kovarik, 1996, by having a palpal bulb with a very short and acuminate embolus and four short keels; separated tibial apophysis; and female spermathecae resembling those of Cyrtopholis, with two seminal receptacles with elongated ducts emerging from a common area. Cyrtopholis palmarum Schiapelli & Gerschman, 1945 and C. schmidti Rudloff, 1996 from Brazil and Acanthoscurria acuminata Schmidt & Tesmoingt in Schmidt, 2005 from Bolivia are transferred to the new genus. The female of Umbyquyra palmarum (Schiapelli & Gerschman, 1945) gen. et comb. nov. and the male of U. schmidti (Rudloff, 1996) gen. et comb. nov. are described for the first time. Cyrtopholis zorodes Mello-Leitão, 1923 is considered a junior synonym of Acanthoscurria gomesiana Mello-Leitão, 1923 and Cyrtopholis meridionalis (Keyserling, 1891) is considered a nomen dubium. Eight new species from Brazil are described: Umbyquyra paranaiba gen. et sp. nov., U. cuiaba gen. et sp. nov., U. araguaia gen. et sp. nov., U. sapezal gen. et sp. nov., U. belterra gen. et sp. nov., U. caxiuana gen. et sp. nov., U. tucurui gen. et sp. nov. and U. tapajos gen. et sp. nov. Data and maps on the geographic distribution are provided.

Midgley JM, Engelbrecht I (2019) New collection records for Theraphosidae (Araneae, Mygalomorphae) in Angola, with the description of a remarkable new species of Ceratogyrus. African Invertebrates 60(1): 1–13. https://doi. org/10.3897/AfrInvertebr.60.32141
During 2015 and 2016 several baboon spider specimens (Araneae: Theraphosidae) were collected in central Angola during surveys undertaken for the Okavango Wilderness Project. These collections represent range and habitat extensions for Pterinochilus Pocock, 1897, Ceratogyrus Pocock, 1897 and Phoneyusa Karsch, 1884. The new species Ceratogyrus attonitifer sp. n. is described from female specimens and the distribution of genera mapped. Central and eastern Angola is severely under sampled for theraphosid spiders, with every species collected during the survey either being potentially new to science or representing a significant range extension for the genus.
Opisany novy druh Ceratogyrus attonitifer.

Perafán, C. & Valencia-Cuéllar, D. (2018). Proshapalopus marimbai, a new tarantula species (Mygalomorphae, Theraphosidae) and first genus record from Colombia. Tropical Zoology 31(4): 200-213. 
A new species of Proshapalopus Mello-Leit~ao, 1923, distributed in the Southwest Colombia in the Choco Region, is described. A morphological cladistic analysis based on the previous matrix of a Theraphosinae group confirmed the inclusion of this species within Proshapalopus. The new species, Proshapalopus marimbai n. sp., can be distinguished from other species of the genus mainly by the reduced number of labial cuspules, around 40; in contrast the other species having over 100. Males can be distinguished by the thickened femur III, presence of intermediate urticating setae type I-III only, palpal bulb with a considerably long prolateral inferior keel (from ventral median depression to embolus apex) and the accessory keel pronounced distally. Females can be distinguished for lacking urticating setae type III and the non-incrassated tibia IV. This discovery constitutes the fourth species described for Proshapalopus and the first record for Colombia, expanding the geographical distribution of the genus, until now known for Brazil only. Other aspects of distribution and the phylogenetic relationship of the new species are also discussed here.

Zonstein, S. L. (2018e). Complementary data on the genus Ischnocolus (Araneae: Theraphosidae). Israel Journal of Entomology 48(1): 105-118. 
The paper provides additional information on the taxonomy of the theraphosid genus Ischnocolus Ausserer, 1871. A new combination is proposed: Ischnocolus elongatus (Simon, 1873), n. comb. (ex Cyrtauchenius). The hitherto unknown males of I. hancocki Smith, 1990 and I. jickelii (L. Koch, 1875) are depicted and described for the first time. Illustrations of the male palpal organ showing its structure in two remaining congeners, I. valentinus (Dufour, 1820) and I. ignoratus Guadanucci & Wendt, 2014, are also provided. The following synonymy is established: Mygale valentina Dufour, 1820 = Leptopelma cavicola Simon, 1889, n. syn. The taxonomic position of species, previously included in Leptopelma Ausserer, 1871, is briefly discussed.
