Euophrys bulbus

: 406
, f. 11–14.
Diagnosis.
Among the congeners, the female of the species is similar to
E. atrata
, but differs in the following: 1) epigynal plate relatively smooth from ventral view, but with obviously hollow in
E. atrata
; 2) spermathecae spherical and much bigger, while oval-shaped in
E. atrata
; 3) copulatory ducts much longer and thinner, which relatively short in the latter. The male is similar to
E. wenxianensis
Yang & Tang, 1979
, but can be distinguished from the latter by: 1) distal half part of embolus suddenly broaden, while whip-shaped in
E. wenxianensis
; 2) tip of RTA stout, while tip sharp in
E. wenxianensis
; 3) palpal cymbium and tibia with dense long white hairs, while absent white hairs in the latter.
