Muma 1989: 13, fig. 14:
MALE HOLOTYPE: Total length 21.0 mm.
CP = 10.0
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
Brookhart and Cushing, 2004: 295, figs 17-19, 34, 40, 46
Pale yellow coloration, palpus, legs pale, anterior region of
propeltidium pale violet, eye tubercle dark. 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). Two
short, pointed ctenidia (Fig. 40), 75–106 palpal papillae (Fig. 19).
Male holotype: Total length 21.0, chelicera length 6.5,

Females: 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
measurements (3): Total length 18.0–22.0, chelicera length
4.71–7.29, chelicera width 2.58–3.33, propeltidium length 2.83–3.33,

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.
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.
