Odontophotopsis mexicana Pitts, NEW SPECIES

(Figs. 38, 40, 44, 45)

Diagnosis. This species is distinguished from others in this species-group by the mesosternal armature, which has dentate ridges bearing 3–4 tubercles that are subequal in height, with the height being less than their width apart (Fig. 38).

Male. Coloration and setal pattern. Head, mesosoma and first metasomal segment ferruginous, antenna slightly paler. Metasomal segments 2–5 darker, dark ferruginous to piceous, apical segments 6–7 somewhat lighter in coloration. Head and mesosoma uniform in color, except ocellar area darkened.

Head. Ocellocular distance 1.33X length of lateral ocellus, and interocellular distance 0.8X length of lateral ocellus. Mandible with three apical teeth and with large basal tooth (Fig. 40); width at ventral tooth 1X basal width of mandible, width at preceding sinus 0.6X basal width of mandible, apical width 0.75X basal width of mandible (Fig. 40). Length of first three flagellomeres: 2.3X, 2.6X and 1.2X length of pedicel, respectively; width of first flagellomere 1.2X length of pedicel.

Mesosoma. Mesosternum armed with dentate ridges, bearing 3–4 tubercles, subequal in height, height less than width apart (Fig. 38). Marginal cell 1.9X length of stigma. Stigma 1.4X length of R1 vein.

Metasoma. T2 apical margin with slightly raised median area of denser fine punctures, light ferruginous. Genitalia as in Figs. 4 and 45. Digitus with basal portion cylindrical, apical portion lobate, flattened, tapering toward apex.

Length. Holotype 15.5 mm. Paratype 10.2 mm.
