  Two New Species of the Genus Brignoliolus Ovtchinnikov, 1999 (Araneae, Agelenidae) from Türkiye Abstract Two new species in the funnel web-weaving spider genus Brignoliolus Ovtchinnikov, 1999 are described from South Anatolia: Brignoliolus zorkunensis sp. n. (♂♀) and B. gurgum sp. n. (♂♀). These new species were found from black pine forest and mixed red pine-oak forest in the south and southeastern regions of Anatolia. Their taxonomic relationships are briefly discussed and a map to species of Brignoliolus from Türkiye is provided.

Re-delimitation of the genus Emertonella (Araneae, Theridiidae, Hadrotarsinae) and taxonomic notes on Euryopis and Phycosoma from China

Abstract

Hadrotarsinae Thorell, 1881 is a subfamily of cobweb spiders (Theridiidae) distributed worldwide and generally regarded as specialized ant predators. The taxonomy of Hadrotarsinae is problematic due to unclear delimitation of genera, leading to likely misplacement of many species. In the current paper, we provide taxonomic amendments for Emertonella Bryant, 1945, Euryopis Menge, 1868, and Phycosoma O. Pickard-Cambridge, 1880 based on Chinese materials. Examination of Eu. deplanata Schenkel, 1936 and Em. taczanowskii (Keyserling, 1886) supports Yoshida’s concept of Emertonella and provides additional morphological evidence for refining the generic diagnosis. Accordingly, Eu. deplanata is formally transferred, with 30 additional species, from Euryopis to Emertonella, and Em. taczanowskii is redescribed. Furthermore, Physcoa mingyaoi (Yin, 2012), comb. nov. ex. Euryopis and Lasaeola stigmosum (Yin, 2012), comb. nov. ex. Phycosoma are transferred, and one new synonym is proposed, Phycosoma amamiense (Yoshida, 1985), syn. nov. = Phycosoma japonicum (Yoshida, 1985). Finally, the first descriptions of the males of Em. deplanata (Schenkel, 1936), comb. nov. and Phycosoma ripa (Zhu, 1998) are provided.
