(Appendix 4: Fig. 5)
Euphoria devulsa Horn 1880: 402.
Original combination. Lectotype at MCZ designated by Hardy (2001), examined. Other syntypes not found; no paralectotypes designated.
Description (n = 23). Length 9.3–10.7 mm; width 5.3–7.3 mm. Color: Body shiny black, elytra occasionally reddish brown, frequently with small, whitish, cretaceous markings. Head: Frons flat, strongly strigose, glabrous to moderately densely setose; setae long, yellowish. Clypeus short, subquadrate, strongly strigopunctate, apex and sides not raised, apex vaguely sinuate in dorsal view. Antennal club shorter than stem, subequal in length in both sexes. Pronotum: Surface densely punctate; punctures lunulate, small to moderate in size, denser towards sides, glabrous to moderately densely setose; setae short to long, yellowish. Base in front of scutellum vaguely to weakly emarginate. Scutellum longer than wide, densely punctate; punctures lunulate, setose. Elytra: Surface densely punctate; striae bearing 3 evenly spaced rows of lunulate punctures, grooves occasionally present. Costae weakly to moderately raised. Posterior half of sutural costa raised in lateral view. Pygidium: Surface concentrically striate, striae discontinuous, glabrous to moderately densely setose; setae short, yellowish. Legs: Apical and medial protibial teeth closer to each other than to basal tooth, females frequently with worn teeth. Mesotibial carina well developed, frequently with 2 sharp, short teeth. Metatibiae moderately expanded apically, metatibial spurs subequal in shape in males, internal spur frequently lanceolate in females. Venter: Mesometasternal process small, extending anteriorly to same level as mesocoxae or slightly beyond, apex variably truncate, moderately densely setose. Mesepimera, metasternum, and metacoxae setose, setae as on legs. Metasternum rugose, setose laterally, glabrous, impunctate at middle. Abdominal sternites laterally setose, abdomen of males flat, slightly convex in females. Male genitalia: Parameres as in Fig. 5c.
Diagnosis. Euphoria devulsa is distinguished from other species in the group by the subquadrate clypeus, striae bearing three evenly spaced rows of lunulate punctures, and the apex of the pygidium sexually dimorphic (round in males, acuminate in females). This species is close to E. levinotata but can be separated based on the striae bearing 3–4 irregular rows of grooves, double grooves, lunulate punctures, and geminate punctures, and the pygidium at its apex being round in both sexes in E. levinotata.
Taxonomic History. Horn (1880) described E. devulsa based on 40 males and 48 females from “near San Antonio, Texas ”, USA. Casey (1915) included E. devulsa in the subgenus Isorhipina with certain doubts about this placement: “ devulsa Horn is probably not closely related to dimidiata and possibly may not belong to this group at all, but not having seen the species I am unable to do more than give the characters assigned by its author.” Hardy (2001) included the species in his “histrionica group” of Euphoria together with E. histrionica, E. subtomentosa, E. lineoligera, E. biguttata, E. canescens, and E. dimidiata.
Natural History. Adults have been collected in flight intercept traps and in nests of N. micropus.
