Zhezhoulinyphia gen. nov. (Araneae, Linyphiidae) from Yunnan, China

Abstract

A new Linyphiinae genus Zhezhoulinyphiagen. nov. from Yunnan Province is described together with its two new species: Z.caperatasp. nov. (♂) and Z.denticulatasp. nov. (♂, ♀). Centromerusyadongensis Hu & Li, 1987 is transferred to Zhezhoulinyphiagen. nov. and a new combination, Z.yadongensis (Hu & Li, 1987), comb. nov. is proposed.

Acroterius gen. nov. (Araneae: Linyphiidae: Linyphiinae) with twelve new species from Yunnan, China

“…The discovery of this new genus is not surprising, considering that there is limited taxonomic research on Linyphiidae from Yunnan. Zhao & Li (2014, 2017, Irfan & Peng (2018, 2019a, 2019b and Irfan et al (2019) already identified 39 species and 10 genera; with the addition of Acroterius gen. nov., the number of linyphiid genera endemic to Yunnan is now eleven. Acroterius gen. nov. appears to be closely related to Zhezhoulinyphia as many species in both genera have been recorded from the same localities and they share similarities in the embolic division and spermathecae shape.…”

“…All measurements are given in millimeters (mm). The terminology used in text and figure legends follows Irfan et al (2019). Specimens are deposited in the collection of the College of Life Sciences, Hunan Normal University (HNU).…”

“…Its average temperature is about 5~24°C. Yunnan Province has a very rich and diverse linyphiid spider fauna as was demonstrated by Irfan et al (2019), who described a new genus Zhezhoulinyphia Irfan, Zhou & Peng, 2019, and by Irfan & Peng (2018, 2019a, 2019b, who mentioned three genera new to China along with six new species, i.e., Herbiphantes acutalis Irfan & Peng, 2019, Houshenzinus tengchongensis Irfan & Peng, 2018, Kaestneria valentissima Irfan & Peng, 2018, Labullinyphia furcata Irfan & Peng, 2019, Paikiniana operta Irfan & Peng, 2018 and Parbatthorax proiectus Irfan & Peng, 2019, from Yunnan. Zhao & Li (2017 described Callosa…”
