Pedicel and flagellomere II subequal in length, flagellomere I slightly longer than pedicel (Fig. 1). Mandible bidentate apically (Fig. 2). Dorsal margin of mandible lacking prominent carina (Fig. 2). Ventral margin of mandible emarginate on basal third with distinct basal tooth (Fig. 2). Genal carina absent. Maxillary palpus 6­segmented, labial palpus 4­segmented. Decumbent plumose pubescence present on frons and vertex. Mesosoma. Pyriform, slightly longer than wide, widest medially (Fig. 4). Anterolateral margin of pronotum slightly angulate with vertical carina (Fig. 3). Scutellar scale present with lateral carina connecting scale to propodeal spiracle tubercles (Figs. 3, 4). Propodeum with distinct disk and declivity regions (Fig. 3). Decumbent plumose pubescence present on metasomal dorsum. Femora of all legs rounded apically. Tibial spurs pectinate. Metasoma. First segment subsessile with respect to second, slightly disciform posteriorly (Fig. 5). T2 with lateral felt line. S2 flattened medially, without lateral felt line. T6 with pygidial area defined laterally by carinae. Plumose pubescence present both on surface of tergites and as dense apical fringes. Distribution. Western North America, east to Arkansas, from B.C. Canada south into Central America (Northern Costa Rica). Comments. The genus Odontophotopsis is in the subfamily Sphaeropthalminae (Sphaeropthalmini). Males of Odontophotopsis can be separated from other Sphaeropthalmini by the presence of large ocelli, simple spine­like sternal processes (absent in O. mamata Schuster and in some specimens of species in the O. tapajos speciesgroup), usually with weak sculpturing and the integumental surface polished, presence of incomplete parapsidal furrows (complete in O. fallax Viereck and O. pudica (Melander)), absence of or very short felt lines on the second sternite, presence of well­developed plumose pubescence (especially on the abdomen), and presence of three or four mandibular teeth (mandibles bidentate in the O. unicornis species­group) (Schuster 1958). The female of Odontophotopsis can be distinguished from females of other sphaeropthalmine genera by the following combination of characters: presence of plumose pubescence, absence of dorsal carina on the antennal scrobe, antennal flagellomere I being only slightly longer than the pedicel, absence of genal carina, presence of a scutellar scale connected to a transverse carina, first metasomal segment subsessile and slightly disciform, and presence of lateral carinae defining pygidium. These characters are thought to be of generic importance and were chosen after a survey of approximately ten other undescribed probable Odontophotopsis females. Because the female of only one of 59 species has been described, it is unclear which characters are autapomorphic, if any, for the females and it is anticipated that the generic description will need to be modified as more females are described. Several described female species currently placed in Sphaeropthalma (Photopsis) Blake but not associated with males may be Odontophotopsis species, such as S. (P.) arota (Cresson), S. (P.) ceres (Fox) and S. (P.) zenobia (Blake), as well as several others. However, these species do not completely match the above generic description. As such, we feel that we should attain a better understanding of the generic characters for Odontophotopsis females by studying females from definitive sex associations before placing described species into Odontophotopsis. In the key to the mutillids of the United States (Manley and Pitts 2002), the Odontophotopsis female will terminate at couplet 16 with a choice between Dilophotopsis Schuster and Sphaeropthalma (Photopsis). Dilophotopsis females are much larger in size, have a transverse carina on the antennal tubercle, have a dorsal carina abruptly terminating at a distinct denticle on the basal third of the mandible (Fig. 8), have a granulate pygidium, and exhibit differences in plumose pubescence and the shape of the first metasomal segment. Photopsis females that could be confused with Odontophotopsis, such as S. (P.) orestes (Fox) or S. (P.) marpesia (Blake) have a dorsal carina on the antennal scrobe, have a granulate or coarsely rugose pygidium, and lack a scutellar scale. This last character may not be a reliable generic character because it is known to vary within other genera, such as Dasymutilla Ashmead.
