Re-examination of the crab spider species Oxytate minuta Tang, Yin et Peng, 2005 (Araneae: Thomisidae) Author Jin, Chi Author Zhang, Feng text Zootaxa 2012 3588 64 67 journal article 10.5281/zenodo.283157 333577fe-2057-43a7-a9ca-44e1e4164bbb 1175-5326 283157 Indoxysticus tangi Jin and Zhang , comb. nov. et replacement name ( Figs 1–10 ) Replacement name for Oxytate minuta Tang, Yin et Peng, 2005 : 733 , figs 1–3 (preoccupied by Indoxysticus minutus ( Tikader, 1960 ) : 173, figs 1a–b). Diagnosis. The female of this species is similar to I. minutus in general appearance, but differs in the position of the transverse hood of the epigyne, which is on the posterior margin of the chambers (hood on the anterior margin of the chambers in I. minutus ). The male can be easily separated from I. minutus by the RTA with hooked tip (RTA with conical tip in I. minutus ), and by the bulb with no projecting subtegular prong prolaterally (bulb with subtegular prong in I. minutus ). Description. Male (from Wuyi Mountain). Total length 3.27. Prosoma 1.43 long, 1.43 wide; opisthosoma 1.84 long, 1.28 wide ( Fig. 3 ). Dorsal shield of prosoma slightly convex, dark yellowish-brown, sides black brown, with long setae sparsely. Clypeus height 0.13, clypeus with 7 long setae and a small white marking. FIGURES 1–6.

Opisthosoma dorsally yellow with transverse grayish markings, white spots and long setae; sides grayish; venter yellow. Palp as in Figs 5–8 . VTA broad digitiform, RTA extremely extend with hooked tip and the tip directed dorso-laterally; embolus (starting at 8 o’clock position) large and thick, its tip heavily sclerotized, twisted, triangle shaped in ventral view; tegulum membranous.
