Triepeolus shoshone Onuferko & Rightmyer, 2024, sp. nov.

Triepeolus shoshone sp. nov. urn:lsid:zoobank.org:act: E7F437ED-E934-4E01-9FCC-3151D1C3EF6F Figs 12O, 15F, 30 Proposed common name Shoshone triepeolus. Diagnosis The following morphological features in combination tell T. shoshone sp. nov. apart from all other Triepeolus in the simplex species group except T. apache sp. nov.: the T1 basal band forms an inflexed arch and is thus gradually narrowed but not completely interrupted medially, such that the discal patch has a short, narrowed (i.e., inverted V-shaped) anteromedial projection (Figs 15F, 30B), and the legs are entirely reddish orange from trochanters to tarsi (Fig. 30A–C). Whereas in T. apache the T1 apical transverse band is interrupted or (less commonly) at least narrowed medially and the T2 apical transverse band is narrowed or interrupted medially, in T. shoshone T2 and usually also T1 have complete apical transverse bands (Figs 15F, 30B). Although it might not be possible to separate certain individuals morphologically, throughout most of its range T. shoshone can be separated from T. apache by geography; the former is a northern species whose known range extends from northern Arizona and northern New Mexico to Western Canada whereas the latter is a southern species known only from the Southwestern United States and adjacent Mexico. Etymology This species is named for the Shoshone people, whose traditional territory spans much of its known range.

Description MEASUREMENTS OF HOLOTYPE. Body length 9.8 mm; ITW 2.3 mm; head length 2.6 mm; head width 3.6 mm; fore wing length 8.2 mm (margins of both worn). Female INTEGUMENT COLORATION. Dark brown to black except as follows. Mandible with apical third golden yellow (entirely dark brown/black in some paratypes). Mandible with basal two-thirds; labrum along apical and lateral margins; scape, pedicel, and F1 extensively; succeeding flagellomeres to some extent; tegula; coxae to some extent; trochanters to tarsi (excluding brown meso- and metatibial spurs) entirely; metasomal terga laterally; and pseudopygidial area with underlying integument, pygidial plate, and metasomal sterna to some extent reddish orange. Fore wing membrane subhyaline, apically dusky. Hind wing membrane dusky subhyaline to hyaline. PUBESCENCE. Face with tomentum densest around antennal socket. Clypeus, upper paraocular and frontal areas, and vertexal area mostly exposed. Pronotal collar with tomentum uniformly pale yellow. Mesoscutum with well-defined paramedian band of pale-yellow tomentum, tapering slightly toward but not attaining anterior margin; pale tomentum otherwise mostly restricted to lateral and posterior margins. Mesopleuron with off-white to pale-yellow, appressed, branched setae; upper half densely setose, except behind pronotal lobe, with setae slightly sparser on hypoepimeral area; ventrolateral half sparsely setose. Mesopleuron with sparse, pale-yellow, erect/suberect, simple setae (less than ½ MOD in length) in addition to usual appressed, branched setae. Metanotum with tomentum uninterrupted, uniformly pale yellow. Propodeal triangle mostly glabrous, with (pale) setae restricted to small lateral patches. Metasomal terga with bands of pale-yellow tomentum. T1 with apical transverse band complete (narrowly interrupted medially in some paratypes), transverse bands subparallel, discal patch transversely oblong or trapezoidal with short, narrowed (i.e., inverted V-shaped) anteromedial projection. T2–T4 with complete apical transverse bands, those of T2–T3 medially somewhat removed from apical margins of terga, that of T2 with pair of basomedially convergent anterolateral extensions. T5 with large patch of pale-yellow tomentum on each side lateral to pseudopygidial area. Pseudopygidial area with triangular region of posteriorly directed setae with three subregions (basal patch of dense, golden setae; darker subapical band of sparser, coppery brown setae; and apical row of dense, suberect, silvery setae) within larger trapezoidal space of posteromedially directed coppery brown setae. S2–S3 with apical transverse bands of white tomentum (ill-defined and/or reduced to posterolateral patches in holotype and some paratypes). S4 with apical transverse band of white tomentum. S5 with apical fimbria of coppery bristle-like setae. SURFACE SCULPTURE. Labrum coarsely and densely (most i <1d) rugose-punctate. Clypeus densely punctate (most i≤ 1d) but interspaces well defined, shining; with many small punctures among larger ones. Vertexal area somewhat sparsely punctate (some i>2d), especially around ocelli. Mesoscutum, mesoscutellum, and axilla with punctures more or less equally dense (most i ≤ 1d); interspaces well defined, shining. Mesopleuron with punctu
