Four new species of Tapinocyba Simon, 1884 (Araneae, Linyphiidae) from Jiangjin District of Chongqing, China

Four new species of the genus Tapinocyba Simon, 1884 are described from Jiangjin, Chongqing: 

  • T. centralis sp. nov. (♂)
  • T. denticulata sp. nov. (♂♀)
  • T. triangularis sp. nov. (♂♀)
  • T. virga sp. nov. (♂♀)

The new species exhibit distinctive genital features, such as a bifurcated embolus tip in the male palp of T. denticulata sp. nov. and T. virga sp. nov., and embolus tip unbifurcated in T. centralis sp. nov. The epigynes display more unique characteristics, such as epigynal plate with a pit ventrally on its frontal face in T. triangularis sp. nov. and T. virga sp. nov., which is absent in all other known Tapinocyba species. Detailed descriptions, along with photographs of genital characters, somatic features, and a distribution map, are provided.
