Tegulum egg-shaped, 1.2 longer than wide; tegular apophysis long, more than 4/5 of tegulim length, thin hook-shaped; embolus originates at about 10 o’clock position, terminating at approximately 11 o’clock position, it’s tip covered by conductor; conductor large, membranous.

Epigyne (Fig. 4 D–E). Apron-like atrium distinct, about four times wider than long; receptacles are faintly visible through epigynal plate in ventral view; two copulatory openings located at lateral borders of atrium; the transparent copulatory ducts running spirally (length of spira about 2.6 times longer than receptacles), forming 8 entwined loops (including 4 ascending coils and 4 descending coils); receptacle long and tubular, separated by two diameters.
