Etymology. The specific name is derived from the Latin adjective brevis , -is , - e , meaning “short” referring to the embolus tip shorter than the embolic apophysis. Diagnosis. Males of S. brevis sp. nov. may be recognised by the following combination of characters: 1. Embolus tip distinctly shorter than the embolic apophysis; 2. dRTA wide, with tip slender and finger-shaped in lateral view. Females of S. brevis sp. nov. are similar to those of Sinopoda horizontalis Zhong, Cao & Liu, 2017 ( Zhong et al . 2017 : figs 5A–B, 6A–B) in having the horizontal anterio-lateral margins of lateral lobes and posterior margin of epigyne distinctly bilobate, but differ from S. horizontalis in the glandular appendages of vulva being as wide as posterior parts of spermathecae, with slender ends (slightly wider, with swollen ends in S. horizontalis ).
