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

Triepeolus oblongimacula sp. nov. urn:lsid:zoobank.org:act: A939584A-99F2-4D1C-B4A5-23D778D8B027 Figs 4B, 8B, 9C, 12H, 15C, 23 Proposed common name Oblong-spot triepeolus. Diagnosis The following morphological features in combination tell T. oblongimacula sp. nov. apart from all other Triepeolus in the simplex species group: the axillae are entirely black and large, each with the tip extending beyond the midlength of the mesoscutellum (but not as far back as its posterior margin) and the free portion distinctly pointed, hooked (i.e., concave along the medial margin), and mesally unattached to the mesoscutellum for more than a third the medial length of the axilla (Fig. 23B); the mesopleura laterally do not have erect/suberect, simple setae or have only sparse, short (<¼ MOD), erect/suberect, simple setae in addition to the usual appressed, branched setae (Fig. 9C); the trochanters are normal (i.e., not tuberculate) (Fig. 9C); the dorsum of the mesosoma and metasoma have bands of pale-yellow tomentum (Figs 8B, 15C, 23); and the T1 discal patch is broadly rounded laterally and rod-shaped with an inverted U- or horseshoe-shaped anteromedial projection (Figs 15C, 23B). Triepeolus oblongimacula most closely resembles T. obliteratus and T. rhododontus, but in T. obliteratus the dorsum of the mesosoma and metasoma have bands of pale-gray to white/off-white tomentum, the legs are never (as opposed to commonly; Fig. 23A–C) entirely reddish orange from trochanters to tarsi, and the pseudopygidial area of the female is never (as opposed to uncommonly) reddish orange, and in T. rhododontus the T1 discal patch is somewhat narrowed and/or curved posterolaterally and thus allantoid and the axillae commonly have reddish tips, especially in the West where the species’ range overlaps with that of T. oblongimacula. Etymology The specific epithet is a Latin noun in apposition meaning ‘oblong-spot’ and refers to the shape of the T1 discal patch.

Body length 11.7 mm; ITW 2.4 mm; head length 2.7 mm; head width 3.9 mm; fore wing length 8.6 mm. Both sexes INTEGUMENT COLORATION. Dark brown to black except as follows.Mandible with apical third golden yellow. Mandible with basal two-thirds (except for extreme base), labrum along apical and lateral margins, F1 to some extent, coxae to some extent, trochanters to tibiae (excluding brown meso- and metatibial spurs) partially to entirely, and tarsi entirely orange. F2 with orange spot basally. Tegula reddish brown. Fore wing membrane subhyaline, apically dusky. Hind wing membrane dusky subhyaline to hyaline. Pygidial plate to some extent reddish brown (difficult to see in holotype because T6 mostly retracted; described from paratypes). 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; 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 nearly bare, except along margins. 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 basal transverse band interrupted medially, apical transverse band complete (narrowly interrupted medially in some paratypes), transverse bands subparallel, discal patch transversely oblong or elliptic. T2–T4 with apical transverse bands complete and medially somewhat removed from apical margins of terga, that of T2 with pair of basomedially convergent anterolateral extensions. S2–S3 with medially interrupted apical transverse bands of white tomentum (reduced to posterolateral patches in holotype and some paratypes). 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 and nearly contiguous (most i <1d). Mesopleuron with punctures in upper half nearly contiguous and denser (i <1d) than in ventrolateral half (i
