Supplementary description

AEDEAGUS ( Fig. 14 D–F). Ventral process of each paramere distinctly narrowed apically, slightly hooked at apex; conjoint dorsal plate of parameres well-developed, distinctly longer than the length of ventral process and wider than the distance between outer margins of ventral processes, slightly narrowed apically, with nearly straight apical margin; laterophyses separated, thin, nearly straight and pointed at apices, situated in middle of dorsal side of median lobe, distinctly shorter than conjoint dorsal plate.

ABDOMINAL STERNITE VIII Oŀ ŀEMALE ( Fig. 16D ). Distinctly and widely emarginate in middle of posterior margin, the middle emargination moderately and triangularly protuberant in middle of bottom margin, lateroapical angles narrowly rounded.

INTERNAL ORGAN Oŀ REPRODUCTIVE SYSTEM ( FIG. 15D ). Vagina stout, abruptly thinned and extended into a short and thick duct at apex; diverticulum and spermathecal duct arising from the end of the duct of vagina; diverticulum moderately long, spiral and abruptly thinned apically; spermathecal duct very short, distinctly thinner than basal portion of diverticulum; spermatheca composed of a spiral tube, which is slightly shorter than diverticulum, provided with a thin accessory gland, which is distinctly shorter than the spiral tube of spermatheca; median oviduct situated at apex of vagina.

Remarks

The aedeagus was illustrated in ventral view by Wittmer (1982), here it is illustrated again and also in dorsal and lateral views. Besides, the genitalia and abdominal sternite VIII of female are illustrated and described for the first time.

Distribution

Taiwan.
