Diagnosis. FEMALE. The female of this species (Fig. 23) can be separated from other Dasymutilla by the following combination of characters: the integument of the head and mesosoma is pale orange to red, there is a narrow scutellar scale, there are no transverse carinae anterior to the scutellar scale, and the propodeum is punctate or weakly reticulate. MALE. The male of this species can be separated from other Dasymutilla by the following combination of characters: the tegulae are coarsely punctate (Fig. 4), the mesonotum is raised and expanded laterally (Fig. 4), and T3–7 are clothed entirely with black setae (Fig. 35). Description of male genitalia (Figs 68–71). Free length of paramere dorsally curved apically, with ventral brush of long dense setae basally, remainder having scattered short sparse setae; paramere not kinked laterally. Cuspis laterally compressed, ~0.75 × free-length of paramere, having long setae throughout, setae of outer surface longer and denser; outer row of setae anteriorly directed, inner row posteriorly directed. Densely setose basal lobe present. Digitus laterally curved internally, tapering slightly at apex, asetose, ~0.4 × free-length of paramere. Penial valve emarginated anterodorsally, ventral margin bidentate apically, teeth separated, unidentate medially; having longitudinal row of setae at apex and subapically on external margin. Length. Females: 5.5–13.5 mm; males: 7.5–14.5 mm. Host. Bembix cinerea Handlirsch (Hymenoptera: Crabronidae) (Krombein 1958); Trypoxylon politum (Say) (= albitarse Fabricius) (Hymenoptera: Crabronidae) (Fattig 1943); and Nomia melanderi melanderi Cockerell (Hymenoptera: Halictidae) (Krombein 1958).

Remarks. Our phylogenetic results recover D. vesta nested within a clade that includes the entirety of the D. monticola species-group (Fig. 72, 73). As such, we consider D. vesta a member of the D. monticola speciesgroup, making it the most widespread and commonly collected species in this group. There is significant variation in coloration, most readily noticed in the mesosomal and metasomal integument of males and in the tergal setae of females. Prior to this publication, no inferences were made concerning the relation of this widespread and polymorphic species to other species-groups. The absence of gray setae on the apical terga of males and absence of propodeal modifications of females prohibited past authors from associating this species with the D. monticola species-group. There are similarities between D. vesta and selected members of the D. monticola species-group, though. In females, there is a well-defined scutellar scale without any transverse carinae situated anterior to the scale; this trait is shared by
