The genus Jacaena Thorell, 1897 from southern China (Araneae: Liocranidae)

Abstract

Six species of the genus Jacaena Thorell, 1897 from China were studied, including two known species, J. jinxini Liu & Xu, 2020 and J. zhui (Zhang & Fu, 2011), and four new species: J. aspera sp. n. (♂, ♀) from Yunnan and Chongqing, J. bannaensis sp. n. (♂, ♀) from Yunnan and Hainan, J. luteolus sp. n. (♂) from Guangdong and J. menglaensis sp. n. (♂) from Yunnan. A distribution map of Jacaena species in China is provided.

On two new Oedignatha species from Xishuangbanna, China, and the first description of the female of Jacaena menglaensis Mu & Zhang, 2020 (Araneae, Liocranidae)

“… aspera (cf. Figs 1 , 2 with Mu and Zhang 2020 : 336, figs 1d–f, 2d–f, 3a–e): the males have a similar embolus and retrolateral tibial apophysis (Fig. 2A–C ), and the females have a similar spermatheca (Fig.…”

“… zhui (cf. Figs 1 , 2 with Zhang and Fu 2011 : 71, figs 1–15 and Mu and Zhang 2020 : 345, figs 7a–i, 8a, b): the males have a similar embolus and retrolateral tibial apophysis (Fig. 2A–C ), and the females have a similar fertilization duct (Fig.…”

“…The genus is endemic to southeast Asia, and currently contains 16 species. Among these species, seven are known to occur in China: J. aspera (♂♀), J. bannaensis (♂♀), J. jinxini Liu & Xu, 2020 (♂♀), J. luteolus Mu & Zhang, 2020 (♂), J. menglaensis (♂), J. tengchongensis Zhao & Peng, 2013 (♀), and J. zhui (♂♀). Diagnosis.…”

“…Prior to the current study, two genera and five species of liocranid spiders have been described from Xishuangbana: Jacaena aspera Mu & Zhang, 2020 (♂♀), J. bannaensis Mu & Zhang, 2020 (♂♀), J. menglaensis (♂), J. zhui (Zhang & Fu, 2011) (♂♀), and Paratus sinensis Marusik, Zheng & Li, 2008 (♂♀). In this paper, we provide the first female description of J. menglaensis and describe two new species of Oedignatha discovered within the XTBG.…”
