Stactobiella biramosa MARTYNOV 1929 , 297, figs. 5–6.

Remarks. This species is recorded from China for the first time. The male genitalia of our specimen from northern China are quite congruent with the drawings of Stactobiella biramosa provided by AREFINA et al. (2002), apart from the fact that 1) the pair of darkened bars within tergum X are not obvious (clearly observed in the specimens illustrated by AREFINA et al.), 2) the median spine on the lateral margin of each inferior appendage is absent (present on inferior appendages of the specimens of AREFINA et al.). The male genitalia of our specimens are redrawn here for comparison.
