Description

See Hsiao (1944) for further diagnostic characters.

FEMALE GENITALIA. Bursa copulatrix nearly ovoid; sclerotized ring rounded; dorsal labiate plate (DLP) narrow, elongate toward caudal direction; seminal depository strongly inflated, globose, with pair of large, ovoid rings (Figs 37, 39–40); posterior wall of bursa copulatrix membranous, covered with minute, brush-like microprocesses (Fig. 38); gonapophysis 8 broadened subapically and distinctly pointed apically (Fig. 41); gonapophysis 9 pointed apically, strongly serrate subapically (Fig. 42).

Rhinophrus borneensis can be distinguished from R. hsiaoi by black antennal segment I (brown in R. hsiaoi) and the shape of the parameres (Gorczyca 1996).
