Dasymutilla mazatlanorum Manley & Pitts , new species

Holotype male, Mexico, Mazatlan, III-27-79, L. D. French [ UCDC].

Diagnosis of Male (Plate C6E). This species can be differentiated from others by the following combination of characters. The integument of this species is entirely black, while the setae on the dorsum are predominantly orange and setae on the sterna are white. The mandible is bidentate, the antennal scrobe is carinate dorsally, sternum II has a median pit filled with setae, the pygidium is granulate, and lacks an apical fringe of setae.

Description. Male: Length, 7–8 mm. Head. Black; mandible acute at apex, with inconspicuous inner tooth near apex; clypeus flat, anterior margin nearly straight; scape distinctly bicarinate, clothed with sparse pale setae; flagellomere I slightly shorter than remaining segments; antennal scrobe carinate; front and vertex with coarse contiguous punctures; vertex with raised conical area bearing ocelli; occipital region compressed laterally; front and vertex with white to orange setae.

Mesosoma. Black; anterior margin emarginate medially, anterior face of emargination glabrous, impunctate; mesosoma, except metapleuron, with coarse contiguous punctures; lateral process of scutellum long, posterior half glabrous; tegula black, posterior half glabrous, shining, clothed with orange setae; pronotum, mesonotum, and scutellum with dense orange setae; remainder of mesosoma with sparse black setae.

Legs black, clothed with pale setae.

Wings dusky.

Metasoma. Black; metasoma with relatively coarse contiguous punctures; pygidium granulate, lacking apical fringe of setae; sternum I with longitudinal carina produced posteriorly into tooth; sternum II with median pit filled with setae; posterolateral angle of last sternite not dentate, with shallow separated punctures, except apical third impunctate and produced into median tooth.

Genitalia ( Plate 2D ). Paramere with apex dorsally curved, ventral margin of basal 0.3 densely pubescent, remainder with short sparse setae; cuspis cylindrical, laterally flattened, sparsely setose throughout, length about 0.75X free length of paramere, densely pubescent elongate basal lobe present; digitus linear, tapering towards apex, slightly knob-like apically, length slightly less than 0.5X free length of paramere; penial valve bidentate, teeth separate, anterior tooth larger than posterior tooth.

Female. Unknown.

Paratype. ♂, MEXICO, Sonora, San Jose Beach, 40 mi. SW Ciudad Obregon, V-16/23-61, Howden and Martin ( DGMC) .

Distribution. Mexico (Sinaloa, Sonora).

Etymology. In reference to the type locality of Mazatlan, Mexico.

Remarks. This species is known only from two males. The tip of the metasoma is broken off the holotype and is glued to the locality label.
