description: Dasymutilla bimaculata Manley & Pitts, new species   
Holotype male, Mexico, Sonora, El Cobre, IX-30-33 [LACM].  
 Diagnosis of Male (Plate C2B). This species has the integument entirely black except for a pair of yellow/ orange maculae on tergum II, and has conspicuous yellow/orange setae clothing most of the dorsum. The genitalia has an elongate widened cuspis (Plate 1C). The coloration superficially resembles D. chiron ursula, that is also found in Mexico. It differs from the latter species in having a pit on sternum II that is densely filled with setae. This species has an apical fringe of setae on the pygidium, and has the antennal scrobe carinate dorsally.   
 Description. Male: Length, 14 mm. Head. Black; mandible worn, blunt at apex, no apparent inner teeth; clypeus slightly concave, broadly emarginate on anterior margin; scape conspicuously bicarinate, coarsely punctate; flagellomere I slightly shorter than remaining flagellomeres (at least 0.75X length); antennal scrobe distinctly carinate; occipital region slightly depressed laterally; front and vertex with conspicuous yellow setae, remainder of head with black setae; head distinctly narrower than mesosoma.   
 Mesosoma. Black; anterior margin distinctly emarginate medially, anterior face of emargination glabrous; lateral processes of scutellum broad, punctate; tegula black, glabrous, clothed with black setae; pronotum, mesonotum and scutellum with conspicuous yellow setae, remainder of mesosoma with black setae; mesosoma, except metapleura, with coarse contiguous punctures.   
Legs black, clothed with black setae; apices of middle and hind femora rounded, neither squarely truncate nor sulcate.  
Wings infuscated.  
 Metasoma. Black, except for two separated, circular yellow/orange maculae on tergum II; pygidium glabrous, shining, with distinct apical fringe of black setae; sternum I with median longitudinal carina nearly entire length of segment, produced into small blunt tooth posteriorly; sternum II with median pit densely filled with setae; apical sternum with shallow separated punctures, except apical fourth glabrous, bidentate medially; first segment with black setae, except apical fringe yellow, remainder of metasoma with conspicuous yellow setae.   
 Genitalia (Plate 1C). Paramere with apex dorsally curved, ventral margin of basal 0.75 densely pubescent, remainder with short sparse setae; cuspis cylindrical, dorsoventrally flattened, abruptly tapering at apex almost appearing notched, with thick long setae throughout, ventral base more densely setose, length about 0.8X free length of paramere, densely pubescent basal lobe present; digitus linear, tapering towards apex, slightly knob-like apically, length about 0.3X free length of paramere; penial valve bidentate, teeth separate and roughly equal in size.   
 Female. Unknown.   
 Distribution. Mexico (Sonora).   
 Etymology. From the Latin “bi” for two and “macula” for spot, in reference to the two yellow/orange spots on tergum II.   
 Remarks. This species is known only from the male holotype. Although it superficially resembles D. chiron ursula, it can be distinguished from the latter in having a pit on sternum II that is densely filled with setae.
