Eremobates hodai ►Muma 1989: 13, fig. 14; ►Brookhart and Cushing 2004: 295, figs 17-19, 34, 40, 46; ►Brookhart and Brookhart 2006: 313.

HOLOTYPE: Male (holotype) labeled "College of Idaho" with no other collection data. Deposited in FSCA.

Coloration and markings similar to mormonus and seaber. Markings seem to be confined to margins of propeltidium and abdominal tergites. Structure as in mormonus but lacking scopula and ctenidia. Figure 14 of cheliceral profile also illustrates ECCS under normal light at 140x magnification.

Chelicera pale with no stripes, typical dentition, FF crimped in ectal view, MF with posterior IT separate from PT, no cleft under AT (Fig. 34).

Coloration as in males. Chelicera typical, posterior IT separate from PT, no cleft under AT (Fig. 17). Genital opercula similar to
E. scaber with long, broad arms, medial margin slightly curved inward, wings offset, long, posterior margin short ending in a point (Fig.18). Female measurements (3): Total length 18.022.0, chelicera length 4.717.29, chelicera width 2.583.33, propeltidium length 2.833.33, propeltidium width 4.175.00, palpus length 13.015.0, first leg length 11.013.0, fourth leg length 18.021.0.

DISTRIBUTION: UNITED STATES: Idaho, Oregon.

PUBLISHED RECORds: UNITED STATES: Idaho: Ada County - Eagle (4341'N, 11621'W), August 1987 (W.H. & Mary Clark), 2 ♀ (ID); Butte County -  30 Km E of Arco, 6 June 1987 (W.H. & Mary Clark), 1 ♂ (ID); 41.8 Km SE of Howe (W.H. & Mary Clark), 1 ♀ (ID); 35.4 Km SE of Howe, 216 July 1987 (P. Blom, W.H. Clark), 1 ♂ (ID). Oregon: Baker County - Sumpter (label says Idaho) (45059N, 113449W), 26 July 1995 (W.H. & Mary Clark), 1 ♂, 1 ♀  (ID).

nOTES: Muma (1989) believed this species to be most closely related to E. mormonus (Roewer), noting that it could be readily distinguished by its lack of a scopula and its lack of ctenidia. He noted that its pale coloration also indicates a relationship with E. scaber.  Brookhart and Cushing (2004) regarded this species as related to E. scaber and E. clarus from which they noted that it differs in coloration, shape of fondal notch, and female genital opercula. They further commented that, although the holotype lacks palpal papillae and ctenidia; other male specimens have papillae and ctenidia. Brookhart and Cushing (ibid.) also noted that Eremobates hodai was found in the Snake River Plain region of the Columbia River Plateau, and that Allred & Muma (1971) identified E. septentrionis (later known as E. ascopulatus and E. ctenidiellus) from this region, but were in error. Finally, they noted that, although this species may later be synonymized with E. clarus or E. scaber, its small A/CP and its pale lemon coloration led them to separate it at the time. Brookhart and Brookhart (2006) included the species in an annotated checklist of continental North American Solifugae.
