Thaiderces vulgaris (Deeleman-Reinhold, 1995) comb. nov. (Figs 13–14, 15)

Psildoerces vulgaris Deeleman-Reinhold, 1995: 18, f. 29–32.

Material examined. 1 male, 1 female, Thailand, Nakhon Nayok Province, Muang District Forest near Lah Rak waterfall (14º17.472’N, 101º14.888’E; elev. 82 m), 13 November 2014, leg. Q. Zhao.

Diagnosis. The males of the two species of Thaiderces Li & Li, gen. nov. are very similar; distinguishing them is discussed under T. jian Li & Li, sp. nov. The female of this species is easily distinguished by the two pairs of relatively short spermathecae with the lateral pair longer than the medial pair (Fig. 14A).

Description. Described by Deeleman-Reinhold (1995).

Comments. This species is transfered to Thaiderces Li & Li, gen. nov. because it possesses the somatic characters that diagnose the genus.

Distribution. Thailand (Nakhon Nayok Province).
