On the clubionid spiders (Araneae, Clubionidae) from Xishuangbanna, China, with descriptions of two new genera and seven new species

Abstract

Clubionid spiders from Xishuangbanna, Yunnan Province, China are studied. A total of seven genera and 13 species have been found, including two new genera with one new species each, i.e., Ramosatidia Yu & Li, gen. nov., with R. situ Yu & Li, sp. nov. (♂♀) as the type species and Sinostidia Yu & Li, gen. nov., with S. shuangjiao Yu & Li, sp. nov. (♂♀) as the type species. Five additional new species are Sinostidia dujiao Yu & Li, sp. nov. (♂♀), Matidia xieqian Yu & Li, sp. nov. (♂♀), Nusatidia changao Yu & Li, sp. nov. (♂♀), N. mianju Yu & Li, sp. nov. (♀), and N. subjavana Yu & Li, sp. nov. (♀). The following genera and species are reported from China for the first time: Malamatidia Deeleman-Reinhold, 2001, Pteroneta Deeleman-Reinhold, 2001, Malamatidia zu Jäger & Dankittipakul, 2010, Nusatidia aeria (Simon, 1897), N. camouflata Deeleman-Reinhold, 2001, Porrhoclubiona pteronetoides (Deeleman-Reinhold, 2001), and Pteroneta ultramarina (Ono, 1989). Malamatidia christae Jäger & Dankittipakul, 2010 syn. nov. is a junior synonym of Malamatidia zu. Nusatidia rama Deeleman-Reinhold, 2001 syn. nov. is synonymised with N. aeria (Simon, 1897).

One new genus and four new species of Liocranidae Simon, 1897 (Arachnida, Araneae) from China and Vietnam

“…The genus can also be distinguished from Clubionidae in Asia by the posterior median eye tapeta forming 90° angle (Fig. 11A–C ), but absent in Clubionidae ( Ramírez 2014 ), endites with diagonal depression in the middle (Figs 8B, D , 10C ), but absent in Clubionidae (e.g., figs 1G, 2G in Zhang et al 2021a ; figs 2H, 4H in Zhang et al 2021b ; figs 2H, 12H in Zhang et al 2021c ), ocular area covering three-fifths of the anterior width of the carapace (Figs 8A, C , 10A ), but four-fifths in Clubionidae (e.g., figs 1F, 2F in Zhang et al 2021a ; figs 2E, 4E in Zhang et al 2021b ; figs 2E, 8E in Zhang et al 2021c ), wall of the primary spermathecae and secondary spermathecae almost uniform (Fig. 7B ), but bursae thin-walled and spermathecae thick-walled in Clubionidae (e.g., figs 6D, 8D in Zhang et al 2021a ; figs 2D, 4D in Zhang et al 2021b ; figs 14D, 16D in Zhang et al 2021c ).…”
