FF regularly curved; MF with large PT and AT, no cleft under AT, posterior IT in the notch of PT, MST tiny to absent. Fondal notch wider than long (Fig. 29); ctendia 4 flat, swordlike, extending slightly more than half the length of succeeding sternite (Fig. 37); 801 papillae on palpal scopula. Apical plumose bristle covers most of mesal groove. Male measurements (5): Total length 15.0.–23.0, palpus length 10.0–22.0, first leg length 9.0–14.5, fourth leg length 14.5–23.0, chelicera length 3.5–5.4, chelicera width 1.6–2.6, propeltidium length 1.6–2.8, propeltidium width 2.00–3.85.

Coloration same as males. Chelicera typical of species; MF with posterior IT in the notch of PT, no cleft under AT. MST indistinct to absent. Genital operculum similar to E. zinni and E. socal, new species as in fig. 68, pg. 59, Muma 1951 with short arms, medial surface gently curved ending in a point as in E. zinni and E. similis, short curved wing (Fig. 57). No papillae on metatarsus of palpus; seven tiny hairlike ctenidia were present on one specimen. Female allotype: Total length 19.0, chelicera length 5.1, chelicera width 2.2, propeltidium length 2.3, propeltidium width 3.9, palpus length 12.5, first leg length 11.0, fourth leg length 18.5. Ratios: A/CP 5.75, CL/CW 2.31, PL/PW 5.90, GOL/GOW 0.54. Female measurements (3): Total length 18.5–21.0, chelicera length 4.40–5.02, chelicera width 2.0–2.1, propeltidium length 2.1–3.0, propeltidium width 3.4–3.6, palpus length 11.5–12.0, first leg length 10.5–12.0, fourth leg length 18.0–22.0.

New Mexico: Grant County - Gila National Forest, Signal Peak (32º55'N, 108º10'W), 17 June 1976 (Martin H. Muma), ♀ (allotype of Eremobates mimbrenus) (FSCA). 

nOTES: Brookhart and Cushing (2004) regarded this species as closely related to E. similis Muma, noting that it can be distinguished from that species by its darker color, the shape of the fondal notch, the presence of palpal papillae, and the thickness and length of the ctenidia. They cite personal communication from Muma, crediting him with  stating that the 'type' of E. mormonus in the collection of MNHN is not Koch’s type, but may be a lectotype set up by Roewer and therefore invalid.  They note  that no other locality data were given but that the species must have been collected somewhere in southwest Utah based on the presence of other species in that area.  They further noted that they found E. mormonus in northern Arizona around the Grand Canyon, SW Colorado and western New Mexico on mesas with sage, piñon pine-juniper and alpine meadows, and that the Arizona specimens are darker in overall coloration.
Brookhart and Cushing (ibid.) report that this species was erroneously described as E. geniculatus by Muma 1951, who later, after examining the holotype in Paris, identified it as Roewer’s species from Utah (
Eremoperna mormona Roewer 1934).   They also note that Muma's 1989 description of the holotype of E. mimbrenus is correct except that in his drawing of the right male chelicera, the IT is shown on the PT yet on the type specimen itself, the IT is separate.  They note that a male and female contained in the vial with the holotype appear to be E. mormonus, as do two males and a female from the area housed in two other vials.   Further, they observe that Muma’s (1989) description of the female allotype of E. mimbrenus was based on a female with three intermediate teeth on the movable finger collected in a pitfall trap in SW New Mexico, and that a male and a female in the same vial appear to be E. mormonus.  They therefore synonymized E. mimbrenus with E. mormonus.
Brookhart and Brookhart (2006) included this species in an annotated checklist of continental North American Solifugae.
