Enguterothrix simpulum ( Tanasevitch, 2014)

comb. nov.

Apophygone simpulum Tanasevitch, 2014: 395 , figs 8-13, 24-

25.

Type material examined: ZMMU; 5 male and 7 female paratypes of Apophygone simpulum from Khao Yai National Park, Thailand.

Remarks: A comparison of type specimens of Enguterothrix crinipes and E. simpulum revealed that these two species not only belong to the same genus, but are extremely close to each other, slightly differing only in the shape of the male carapace, as well as in small details of the female genitals. The head elevation of the carapace in the male holotype of E. crinipes is slightly larger than in E. simpulum males, while eye size in the latter is significantly larger. The palps of both species seem to be nearly identical. The epigynes in both species are also very similar, but small differences can be observed in the shape of the epigynal plate: in A. simpulum it is somewhat higher but narrower.

Distribution: The species is widespread in northern and northeastern Thailand (see Tanasevitch, 2014).
