No full textDasymutilla imperialis Manley and Pitts Dasymutilla imperialis Manley and Pitts, 2004. J. Kans. Ent. Soc. 77:646. Holotype male, California, Imperial County, Glamis Dunes, 1 mi. W. Glamis, 7 October 1988 (T. Griswold) [EMUS] (examined). Diagnosis of Male (Plate C5C). This recently-described species is easily identified by having both the integument and the setae entirely black, and by the presence of a pit filled with setae on sternum II. Also, the antennal scrobe is weakly carinate dorsally, and the pygidium lacks an apical fringe of setae. Female. Unknown. Distribution. USA (California); Mexico (Baja California Sur). Remarks. This species is known only from the male and from only nine specimens, all of which have been examined.Published as part of MANLEY, DONALD G. & PITTS, JAMES P., 2007, Tropical and Subtropical Velvet Ants of the Genus Dasymutilla Ashmead (Hymenoptera: Mutillidae) with Descriptions of 45 New Species, pp. 1-128 in Zootaxa 1487 (1) on page 58, DOI: 10.11646/zootaxa.1487.1.1, http://zenodo.org/record/508678

Also, the ocellar area is usually concolorous with head, the ocellocular distance is approximately twice the width of the lateral ocellus, the ventral margin of the mandible is angulate (Fig. 8), the mesosternal processes are indistinct, the lamellate process of the middle coxa is longer than wide, and the cuspis has four or more thickened apical setae. Male. Coloration and setal pattern. Coloration and setal pattern similar to other species in species-group. Head. Ocellocular distance 1.5 X length of lateral ocellus, and interocellular distance 1.1 X length of lateral ocellus. Clypeus concave and depressed below dorsal margin of mandible. Mandible slightly dilated apically, with three apical teeth, dorsal carina slightly lamellate medially, and with basal angulation on ventral margin (Fig. 8); width at angulation 1.2 X basal width of mandible, width at preceding sinus 0.75 X basal width of mandible, apical width 0.8 X basal width of mandible. Length of first three flagellomeres: 2.3 X, 2.6 X and 1.2 X length of pedicel, respectively; width of F 1 1.2 X length of pedicel. Mesosoma. Mesosternum armed with single tubercle anteromedially, indistinct, subequal in height, height less than width apart. Mesocoxa with lamellate process, longer than wide. Marginal cell 1.5 X length of stigma. Metasoma. Similar to other species in species-group. Genitalia. Cuspis drastically curving dorsally with inner margin bearing a brush of long setae beginning at apical 0.33 (Figs. 11, 12). Cuspis thick apically, ~ 0.5 X free length of paramere (Figs. 11, 12); densely pubescent setal pit present at knobbed region on dorsal margin 0.33 from base (Figs. 11, 12); apex with thickened long setae (Figs. 11, 12); basal 0.33 with venter slightly punctate and moderately setose (Figs. 11, 12). Digitus with basal portion widest, apical portion lobate, laterally flattened, tapering toward apex. Length. Holotype ~ 9.5 mm. Variation ~7.0– 9.5 mm. Distribution. The Baja California Desert of Baja California, Mexico. Type specimens. Holotype: MEXICO: Baja California, Vermillion Sea Research Station, Bahía de Los Angeles, 17–25.Jun. 1995, T. Jackson (EMUS). Paratypes: MEXICO: Baja California, Vermillion Sea Research Station, Bahía de Los Angeles, 2 males, 17–25.Jun.1995, 2 males, May. 1996, T. Jackson (EMUS). Material examined. MEXICO: Baja California, El Rosario, Hwy 1 S at 115 marker, 24 males, 24– 25.Aug. 1992, D.E. Russell (UCDC). Etymology. Named in honor of Gary Polis. Treat as a noun in opposition. Remarks. This species can easily be mistaken for the other species in this species-group and observing the genitalia is the best means to diagnosis this species. If the mesocoxal lamella is overlooked, the species will most likely be confused with the O. parva species-group, specifically with O. ignacio Schuster, which also occurs in Baja California.Published as part of Pitts, James P., 2007, Revision of Odontophotopsis Viereck (Hymenoptera: Mutillidae), Part 1, with a description of a new Genus Laminatilla, pp. 1-43 in Zootaxa 1619 on page 11, DOI: 10.5281/zenodo.17915
