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).

HABITUS. Carapace flat, red-brown, covered with dense brown and white thin setae, with irregular dark patch on center of eye field (Fig. 41C, F). Chelicerae red-brown, with one retromarginal tooth and two promarginal teeth, bearing dense white setae on base of anterior surface (Fig. 41F). Legs I well-developed, yellow to yellow-brown, with dense dark brown setae on ventral sides of patellae and tibiae (Fig. 41G); other legs yellow. Abdomen elongate-oval, dorsum with irregular dark brown patch antero-medially, and narrow, wave-shaped stripes formed by white setae laterally and posteriorly, covered by white and dark brown thin setae; venter pale to brown, with broad, brown patch medially (Fig. 41C–D).
PALP. Tibia wider than long; RTA stout, with pointed tip transversely directed towards ventral side in retrolateral view; bulb longer than wide, with semicircular membranous extension adjacent to embolic base; sperm duct tapered and extended along bulb margin; embolus tapered and pointed apically (Fig. 40A–C).
