Eleodes subtuberculatus Walker, 1866

( Figs. 18–19 , Map 3 )

Eleodes subtuberculata Walker 1866: 328 . Eleodes letcheri var. vandykei forma parvula Blaisdell

1909: 137.

Eleodes vandykei parvula Blaisdell 1921b: 131 . Eleodes parvula: Boddy 1965: 152 .

Diagnosis. Pronotum small, subcylindrical. Prosternal process deflected. Elytra relatively flat, finely and densely muricate. Profemur mutic in both genders. Probasitarsomere with pencil of dark setae at apex of plantar groove in both genders.

The small, subcylindrical pronotum and relatively flat, finely and densely muricate elytra will distinguish this species from its congeners.

Measurements. Males: length 11.5–12.0 mm; width 4.8–5.2 mm. Females: length 11.0–13.0 mm; width 5.0– 5.2 mm.

Types. Walker’ s type in the BMNH from Vancouver, BC was examined ( Thomas et al. 2014). Holotype of parvula , a unique male ( CASC No. 2829), dissected: The Dalles, Oregon, 18-V-no year given, Hubbard and Schwarz.

Material Examined. C A N A D A: B r i t i s h Columbia: Vancouver. USA: Oregon: The Dalles, Imnah River , 8 mi. E Baker (Wallowa Co.) . California: White Mts., Sheep Mt. , 17,000 ft. (Mono County) . Idaho: Blackfoot, Clearwater , Parker , Anthony (Fremont Co.) . Montana: Monida, West Yellowstone . Washington: Teiton Canyon, Wallula , 10 mi. S Wawawai, N side of Juniper Annex , NE of Pascoe ; 7 mi. W Wallula (Franklin Co.) .

Remarks. We have seen many specimens of this species from sand dunes around Parker and Anthony, Fremont County, Idaho, where it appears to be quite common. Specimens were collected in June and July. Hyslop (1912) described the larval stage.
