Dasymutilla fasciventris: Manley & Pitts 2007: 50 (based on misidentified specimens).

Diagnosis. FEMALE. This is the only member of the D. paradoxa species-group with predominantly reddish integumental coloration. Other diagnostic features include: the clypeus has a basal longitudinal tubercle; the pale setal markings of the head and mesosoma are pale golden; the discal spots of T2 are yellow; T2 and T3 are medially clothed with black setae only; and the pygidium is defined by strong carinae laterally.

MALE. This species can be recognized by the following combination of characters: the hypopygium is flat, lacking a medial longitudinal carina; the mesosoma, legs, and T1-2 are predominantly reddish; and S2 has an anteriorly situated longitudinal seta-filled pit.

Distribution. Madrean and Pacific coastal regions of Mexico (Jalisco, Puebla, Sonora) and USA (Arizona).

Material examined. Type material. Holotype of Dasymutilla fasciventris , ♂, USA, Arizona, [ Gila Co. ], Globe , 12.V.1934, F.H.

Parker ( UCDC) . Other material. MEXICO: Jalisco: Instituto de Biología Chamela : 25.IX.1986, R.B. Miller & L.A. Stange (1♀, FSCA) ; F.D. Parker & T.L. Griswold: 26.IX-8.X.1985 (1♂, EMUS); 1-8.X.1985 (1♂, EMUS); mic. Los Mazos, nr. Autlan , 10.X.2001, F.T. Hovore (1♀, CASC) ; Sonora, 26 km E Alamos , 1- 4.IV.2008 (1♂, EMUS) . USA: Arizona: Patagonia , VII-20-40, D.J. & J.N. Knull (1♂, UMSP) .

Remarks. The males associated with D. fasciventris in Manley & Pitts (2007) are actually an undescribed species (Williams et al. 2012). Because the female is likely already known and this species does not belong in the D. paradoxa species-group, we refrain from describing it at this time. The holotype of D. fasciventris is identical to D. chamela . Like true D. fasciventris , the female D. citromaculosa has the integument predominantly reddish, except the mesoscutum which is blackened and a pattern of bright yellow spots on T2, and the setae mostly black with the head and subapical terga clothed with dense whitish setae. In addition to their identical coloration, D. fasciventris and D. citromaculosa are found in similar habitats across the same geographic range, widely separated from the range of other D. paradoxa species-group members. We therefore treat D. citromaculosa as a junior synonym of D. fasciventris . This is the only member of this group found in the Nearctic region, occurring in mountainous regions of Arizona ( USA) and Sonora ( Mexico).
