Diagnosis

This male of Rhene yunnanensis ( Peng & Xie, 1995) closely resembles R. rubrigera (Thorell, 1887) in having a similar habitus and palp, but differs in: (1) the RTA being horizontally extended towards the ventral side at the distal half in retrolateral view ( Fig. 40C ), whereas extended diagonally upward in R. rubrigera ( Żabka 1985: figs 546, 550, 553); (2) the embolus being longer than RTA in ventral view ( Fig. 40B ), whereas shorter than RTA in R. rubrigera ( Żabka 1985: figs 544, 549, 552). The female also resembles that of R. rubrigera but differs in: (1) the epigynal hood being wider than long ( Fig. 41A ), whereas longer than wide in R. rubrigera ( Żabka 1985: figs 554, 558); (2) the copulatory ducts twisted into L-shape ( Fig. 41B ), whereas coiled into U-shape in R. rubrigera ( Żabka 1985: figs 555, 559, 562).
