Diagnosis. FEMALE. The female of this species can be separated from other Dasymutilla by the following combination of characters: the first flagellar segment is only slightly longer than the second, the mesosoma is clothed entirely with silver or golden setae (Fig. 19), and the apical fringe of T2 is widely black medially (Fig. 19). MALE. The male of this species can be separated from other Dasymutilla by the following combination of characters: the pronotum and mesonotum are clothed with dense silver or golden setae (Fig. 33); the apical terga are clothed with silver setae (Fig. 33); the tegulae are punctate; the propodeal setae are erect, not obscuring propodeal reticulations; and there is a seta-filled pit on S2.

Description of male genitalia (Figs 60–63). Free length of paramere dorsally curved apically, with ventral brush of long dense setae basally, remainder having scattered short sparse setae; paramere laterally kinked in basal 0.2, apices noticeably divergent. Cuspis slightly laterally compressed, tapering apically, ~0.7 × free-length of paramere, having short sparse setae throughout, except external apical 0.5 having dense long anteriorly directed setae. Densely setose basal lobe present. Digitus laterally curved internally, tapering slightly at apex, asetose, ~0.3 × 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: 3.5–7.5 mm; males: 5–9.5 mm.

Host. Unknown.

Distribution. This species is widespread in the western and central Nearctic region, being found from Tamaulipas, Mexico north to Minnesota and west to California and British Columbia, Canada.

Over 200 additional specimens from across the range of this species (USA: AZ, CA, CO, ID, KS, MT, ND, NE, NM, TX, UT, WY; MEX: Sinaloa, Sonora; CAN: AB, BC, SK) were examined (CASC, CISC, CSCA, DGMC, EMUS, PMAE, SEMC).

Remarks. Molecular sequences were used previously to associate D. paenulata and D. caneo with D. monticola (Pigrim et al., 2008) . Our phylogenetic results did not yield any additional synonyms of D. monticola and do not necessitate any additional taxonomic changes (Figs 72, 73). This is the second most widespread member of the D. monticola species-group, after D. vesta . There is variation in punctation of the tegulae and coloration, but this variation is no more extensive than what is seen in other Dasymutilla .
