RESUMO
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), and T. 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.
RESUMO
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.
