Dasymutilla sinaloa Manley & Pitts , new species

Holotype male, Mexico, Sinaloa, Mazatlan, XII-18-88, G. E. Bohart [ EMUS].

Diagnosis of Male (Plate C8E). This species can be recognized by its coloration and several structural characteristics. This species has the integument entirely black, with the setae predominantly bright yellow-orange contrasted with black. Sternum II has a large, oval pit densely filled with black setae, the pit is slightly posterior of center. The pygidium is rugose, with an inconspicuous apical fringe of setae.

Description. Male: Length, 11 mm. Head. Black, clothed entirely with yellow setae; mandible tridentate; clypeus flat, coarsely sculptured, feebly bidentate on anterior margin; scape bicarinate; flagellomere I distinctly shorter than remaining segments; antennal scrobe weakly carinate; occipital region compressed laterally.

Mesosoma. Black, dorsum clothed entirely with conspicuous yellow-orange setae; anterior margin emarginate medially, anterior face of emargination glabrous; mesosoma with coarse contiguous punctures, except metapleuron glabrous; tegula black, glabrous, with yellow setae; lateral process of scutellum long, apical third impunctate; propodeum and pleura with black setae.

Legs black, with yellowish setae.

Wings uniformly fuscous.

Metasoma. Black; pygidium rugose, with inconspicuous apical fringe of setae; sternum I with short sharp longitudinal carina; sternum II with large pit densely filled with black setae, pit about 2X as long as broad, leading edge at center of segment; tergum I and basal third of tergum II with black setae, apical two-thirds of tergum II with sparse appressed yellow-orange setae; apical fringe of tergum II to pygidium with dense erect yellow-orange setae; sternum with sparse yellowish setae.

Genitalia ( Plate 3B ). Paramere with apex dorsally curved, ventral margin of basal 0.3 densely pubescent, remainder with short sparse setae; cuspis cylindrical with thick long setae throughout, length about 0.75X free length of paramere, large elongate densely pubescent basal lobe present; digitus linear, tapering towards apex, slightly knob-like apically, length about 0.5X free length of paramere; penial valve bidentate, teeth separate, anterior tooth larger than posterior tooth.

Female. Unknown.

Distribution. Mexico (Sinaloa).

Etymology. In reference to the type locality of Sinaloa, Mexico; the specific-epithet is a noun in apposition.

Remarks. This species is known only from the male holotype. Key characters are the pit on sternum II distinctly posterior of center, and the pygidium with a thin, inconspicuous apical fringe of setae.
