Male genitalia with median lobe of aedeagus strongly bent, ventral and dorsal margins nearly straight before apex in lateral view; strongly bent to right side in dorsal view; apical lamella narrow, triangular, slightly longer than basal width; base of median lobe strongly bent and expanded, basal orifice about 90° relative to preapical shaft. Internal sac with main flagellum long and slender, slightly sinuous, curved to right side; trumpet-form expansion very small and short, strongly bent ventrally; secondary flagellum and apical bursa present; membrane adjacent to trumpet-form expansion finely scaled (Fig. 89). Female genitalia. Spermatheca simple, moderately long; spermathecal gland inserted at apical two-fifths of spermatheca, not branched, slightly longer than spermatheca; spermatheca slightly expanded and with ring-sculpture at apical one-fourth, basal part of spermatheca without sculpture (Fig. 136). Apical segment of ovipositor scimitar-form, inner margin gradually curved; length four times basal width; inner margin setose in apical half, outer margin setose in apical two-thirds; apex slightly sharp, with membranous extension slightly widened (Fig. 122). Detailed description of external characters has been provided by Tian and Deuve (2001). Distribution (Map 7). All specimen of this species were collected from Tonkin (North Vietnam).
