The name refers to the known distribution of this species, in the region of the Gila River drainage of New Mexico. Diagnosis. The third leg has an unornamented patella and tibia (Fig. 30), unlike all other members of the Habronattus clypeatus group (Figs 1-9). The only other species of the group with green first legs in the male are Habronattus dossenus and Habronattus arcalorus . From Habronattus arcalorus , Habronattus gilaensis differs in many details of ornamentation, especially the third leg. Habronattus gilaensis is most similar to Habronattus dossenus , but differs (in males) in almost complete lack of ornamentation on the third leg, in the paler ocular area, denser and longer fringes on the first leg, denser covering of white setae on the cymbium, and in having the white scales on the side of the carapace broken by a black band extending posteriorly.

Carapace length 2.2; abdomen length 2.0. Structure of chelicerae, legs, and body typical for Habronattus and the clypeatus group. Palp (Figs 27-28) standard for the clypeatus group, very similar to that of Habronattus arcalorus . First legs (Figs 31, 32): Dense fringes of erect setae retrolaterally on the femur, and prolaterally and retrolaterally on the patella and tibia. The setae of these fringes are simple, not swollen as in Habronattus arcalorus . Tibia with two large spatulate macrosetae prolaterally. Third legs (Figs 30, 32): Almost as in female, little modified. Colour in life (Figs 31, 32): Chelicerae dark, with white setae medially. Palp femur and patella covered with beige scales above; cymbium fairly densely covered with white setae. First leg dark above, but with green integument below, and fringes tan to white. Femur of third leg with indistinct transverse bands (Figs 30, 32). Clypeus covered in white setae except for a dark band descending obliquely from each AME. Ocular area light brown to tan, with thin tan bands arching between PMEs. Pale thoracic bands wide anteriorly, narrowing to a point at back margin. Abdomen with basal band of white scales broken at the front by two small black lines (Fig. 31). Longitudinal medial band of pale scales on dorsum of abdomen narrow. Medial longitudinal dark band on underside of abdomen. The dark clypeal bands, pale arching band in the ocular area, and broken basal band are also typical for the clypeatus group. Colour in alcohol: more or less as in life, but with first leg integument yellow-orange, no longer green. Female (focal specimen: paratype, "female 434"). Carapace length 2.6; abdomen length 3.2. Structure typical for Habronattus and the clypeatus group. Epigynum (Fig. 29) with long narrow central pocket in front of which is a small semicircular atrium, as is usual for the species group. Colour: uniform beige to tan scales covering body. Clypeus covered with white scales. Third femur with a hint of the transverse bands seen in the male. Additional material examined.
