Type species

Hexamatia seekhaow gen. et sp. nov.

Diagnosis

Hexamatia gen. nov. is distinguished from most hahniid genera by the combination of the following characters: presence of only six eyes, small body size close to 1 mm, and body pale yellow to white, lacking abdominal patterns in males and having faint chevron lines in females ( Zhang et al. 2011: fig. 23a–b). It can be separated from other six-eyed hahniids by the following combination of characters: from Amaloxenops Schiapelli & Gerschman, 1958 by having a backward curved RTA without twists, and presence of PA on the pedipalp patella and MA on the bulb; from Intihuatana Lehtinen, 1967 by having an unbifurcated RTA, a shorter and bifurcated PA, and presence of MA; and from Scotospilus Zhang, Li & Pham, 2013 by the comparatively short RTA, bifurcated PA and presence of MA.

Etymology

The genus name is formed from two Greek roots: hexa (six) and mati (eye). It refers to the number of eyes present in this genus, one of its diagnostic characters. The gender is feminine.

Composition

Hexamatia seekhaow gen. et sp. nov. and Hexamatia senaria ( Zhang, Li & Zheng, 2011) gen. nov., based on the original description and illustrations.

Distribution

Hexamatia seekhaow gen. et sp. nov. is known from Chiang Mai, Thailand; and Hexamatia senaria gen. nov. from Yunnan, China ( Fig. 8 ).
