Description
3.5 Genus Thaiderces Li & Li, gen. nov.
Type species: Thaiderces jian Li & Li, sp. nov.
Etymology. The genus name is a combination of “Thai” (refers to Thailand) with the second part of “ Psiloderces ”. Gender is masculine.
Diagnosis. The new genus is distinguished (together with Sinoderces) from all other genera by the absence of an apical protrusion on the male cymbium. It is distinguished from Sinoderces by having two teeth on the cheliceral retromargin and the narrow, curved, needle-like tip of embolus.
Description. Cheliceral promargin with dentoid lamina; retromargin with two denticles; male with simple, unmodified cymbium, conductor lacking, embolus arising apically from the bulb, tip of embolus very narrow, curved, needle-like; female with two pairs of spermathecae, one pair longer than the other.
Distribution. Thailand (Yala Province).
Species composition. Thaiderces jian Li & Li, sp. nov., Thaiderces vulgaris (Deeleman-Reinhold, 1995) comb. nov.
