Wuria sumatrensis (K. Viets, 1935)

Figure 4

Material examined — Thailand. 0/3/0, south-side Ubon Ratana Dam , Maha Sarakhan Province, 16°31.395 N 102°30.275 E, 182 m a.s.l., 6 Nov. 2017, 0/1/0 dissected and slide mounted ( RMNH) .

Distribution — This species was originally described from a lake in Sumatra on the basis of a female (K. Viets 1935). In regard to features of the idiosoma (a stripe of sclerite surface with larger pores lying between the medial margins of Cx-III/IV as well between the margins of Cx-II and -III, genital plates relatively wide, L/W ratio 1.2) and a palp as illustrated in Figs. 4A , and – C, the female specimens from Thailand match the description of W. sumatrensis . As emphasized by Wiles (1997) and Pešić et al. (2010), a more certain designation requires males from Sumatra.

Distribution — Widespread in the Oriental region: Known from Indonesia (Sumatra, K. Viets 1935), New Guinea ( Wiles 1997) and India (Assam State; Pešić et al. 2010). New for Thailand.
