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.
