Supplementary description

AEDEAGUS ( Fig. 3 D–F). Ventral process of each paramere wide, slightly narrowed apically, slightly hooked at apex; conjoint dorsal plate of parameres slightly reduced, about one fourth length of ventral process and as wide as one-fourth of the distance between outer margins of ventral processes, slightly narrowed apically, with slightly rounded apical margin.

ABDOMINAL STERNITE VIII Oŀ ŀEMALE ( Fig. 5E ). Distinctly protuberant in middle of posterior margin, the middle protuberance distinctly and roundly emarginate at apex, forming a pair of median lobes, which are narrowly rounded at apices.

INTERNAL ORGAN Oŀ REPRODUCTIVE SYSTEM ( Fig. 4A ). Vagina stout, abruptly thinned and extended into a slightly long duct at ventroapical portion; diverticulum and spermathecal duct arising from the end of the duct of vagina; diverticulum moderately long, spiral and distinctly thinned apically; spermathecal duct slightly longer than diverticulum and distinctly thinner than basal portion of diverticulum; spermatheca composed of a spiral tube which is nearly as long as diverticulum, provided with a thin accessory gland

which is slightly shorter than the spiral tube of spermatheca; median oviduct situated in middle of vagina.

Remarks

In the original publication ( Wittmer 1954), this species was only illustrated with male antennae. Here the genitalia of both sexes and abdominal sternite VIII of female are illustrated and described for the first time.

Distribution
