Chaetotaxy: genu II 2 , 2/0-2/0, 1; genu III 1 , 2/1-2/0, 1. Remarks. According to Chant & McMurtry (2007) , 12 species are presently placed in this genus. The species here reported is distinguished from G . brevisetosus (Collyer) , G . christinae (Schicha) , G . duanensis (Liang & Zeng) , G . eharai (Gupta) , G . hebridensis (McMurtry & Moraes) , G . irregularis (Evans) , G . santosoi (Ehara) and G . semirregularis (Schicha & Corpuz) by having fixed cheliceral digit multidentate and movable cheliceral digit with three teeth. The remaining four species, G. armellae (Schicha & Guttierez), G . ghaiae ( Denmark & Kolodochka), G . liturivorus (Ehara) and G . ricini ( Ghai & Menon) are very similar to each other and to the species collected in this study. However, it is not possible to tell whether the latter corresponds to any of these species because the spermatheca is not discernible.
