Description of female. Female ( Fig. 13 ) similar to male in external morphology; BL 2.38 mm, HL 0.34 mm, HW 0.49 mm; PL 0.68 mm, PWb 0.51 mm, PWm 0.59 mm; EL 1.35 mm, EW 0.89 mm, EI 1.51; AnL 0.96 mm, relative lengths of antennomeres: 1.2: 1.0: 1.2: 1.0: 1.0: 0.9: 0.8: 0.8: 1.0: 1.0: 1.7.

Spermatheca ( Fig. 16 ) large and darkly sclerotized, SpL 0.14 mm, elongate, with a moderately large accessory gland and broad ductus spermathecae with its insertion to spermatheca covered by a corneous sclerite. Female terminalia with a pair of sclerotized structures (see in Figs 14–15 ), located right behind valvifers, forming a ligulate plate, connected by a median membranous structure, in lateral view the paired sclerotized structures each forming a broad, nearly rounded plate; spermathecal duct thin, with its distal part connected to the centre of the membranous structure.
