Diagnosis. Stelis shoshone can be distinguished from all other Nearctic Stelis by the apical white integumental bands of the terga ( Fig 9 View FIGURES 1 – 10 ). Stelis joanae appears superficially similar to S. shoshone but its apical bands are hyaline.
Description. Female: Body length 5.5mm, forewing length 4 mm. Black; reddish medially on mandible, inner margin of fore tibia, tarsi; white bands apically on T1 – T5. Pubescence not thick, plumose, sparse hair on face, mesosoma, terga laterally, erect hair on terga, more dense on apical terga; sterna apically with distinct bands; S6 with short recumbent hair. Punctation fine, close nearly contiguous on most of body but interpunctal area somewhat shiny; T6, S6 closely pitted, dull; Head wider (1.3X) than long; mouthparts short, scarcely extending beyond fossa in repose; clypeal margin crenulate apically; eyes converging below, DLID>(1.3X) BLID; eye wider (1.1X) than gena in lateral view; ocelli normal sized; IOD <(0.9X) OOD> (1.3X) OPD <(1.5X) = LOPD, IOD> (3.0X) LMOD; pronotal lobe not carinate; anterior surface of mesepisternum not concave; scutellum not overhanging metanotum in profile; basal zone of propodeum without distinct pitting; fore, midtibiae with apical spines very short, much smaller than distance between, apical hindtibial spine reduce to low angle, indistinct; TIB>(1.4X) BAT = TAR; terga not lamellate apically, graduli shallow; T6 with apical margin bowed, groove between pseudo and true margin filled with short pile, overlapping S6 ventrally ( Fig. 19 View FIGURES 11 – 20 ); S6 short, not extending beyond T6, apical margin round.
Male. Similar to female except: T7 with transverse apical margin; S3 – S6 forming basin-like depression; apical margins of S1 – S2 rolled over with plumose hair bands apically; S3 with wide V-shaped medioapical depressed area, apical margin straight with plumose hair band; S4 with narrow (0.1X width of sternum) comb, apical margin with plumose hair band, median area depressed, filled with plumose hairs, plumose hair patch laterally; S5 with apical margin shallowly emarginate, impunctate medially, apical margin with row of setose hair, S6 with apical margin flat medially, disc with central area impunctate, depressed.

Holotype and paratypes deposited in BBSL.
Distribution. Known from a single alpine locality in the Bear River Range of northern Utah.
Biology. Specimens of S. shoshone were collected as they searched the ground in the vicinity of patches of Penstemon where its presumed host bee, Atoposmia (Atoposmia) sp. was foraging. These bees were found only in mid August at very high elevations.
Etymology. This species is named in recognition of the Shoshone tribe whose home included the Bear River Range.
