Dasymutilla saetigera Mickel, 1928. U. S. Nat. Mus. Bull. 143: 211. Holotype, Ƥ, Baboquivari Mountains, Arizona, F. H. Snow (SEMC).
Dasymutilla polia Mickel, 1928. U. S. Nat. Mus. Bull. 143: 215. Holotype, 3, Nogales, Arizona, July 20, 1903, Oslar(CUIC), syn. nov.
Diagnosis. FEMALE. The female of this species can be separated from other Dasymutilla by the following combination of characters: the first flagellomere is elongate, the pronotum and propodeum are clothed with appressed silver setae, the mesonotum mesally and the scutellar area are clothed with black setae (Fig. 21), and there is a dense medial patch of appressed setae basally on T2 (Fig. 21). MALE. The male of this species can be separated from other Dasymutilla by the following combination of characters: the pronotum is clothed with dense silver setae (Fig. 34), the apical terga are clothed with silver setae (Fig. 34); the tegulae are asetose and smooth medially and posteriorly (Fig. 3), and there is a seta-filled pit on S2.
Description of male genitalia (Figs 64–67). Free length of paramere dorsally curved apically, with ventral brush of long dense setae basally, remainder having scattered short sparse setae; paramere laterally curved in basal 0.2, apices slightly divergent. Cuspis slightly laterally compressed, tapering apically, ~0.6 × free-length of paramere, having sparse long setae throughout, except outer surface 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: 7–12 mm; males: 5.5– 10 mm.
Host. Unknown.
Distribution. USA (Arizona); Mexico (Nayarit, Sinaloa, Sonora).

Snow (SEMC); D. polia, 3, USA, Arizona, Santa Cruz Co., Nogales, 20.VII.1903, Oslar (CUIC). Other material. MEXICO: Nayarit, 10 mi E Acaponeta, 5Ƥ, 4.VIII.1963, F.D. Parker & L.A.

Nye (EMUS); 2 mi S Sonoita: 83, 1 –14.VIII.2010; 333, 14 –30.VII.2010, E.E. Grissel (EMUS).
Remarks. Based on genetic distances (100% identical in both ITS1 and ITS2) and shared distribution, the male of D. saetigera is D. polia, syn. nov. Although females of D. saetigera had been recorded in northern Mexico, and were included in the treatment of Neotropical Dasymutilla (Manley & Pitts, 2007), males of D. polia were not known from Mexico, and not included in that treatment. Mexican males of D. saetigera will key to couplet 49 (Manley & Pitts, 2007), where they can be separated from D. boharti Manley & Pitts and D. bonita by setal coloration of the apical terga; D. saetigera males have interspersed black and silver setae on T3–7 (Fig. 34).
