Ommatinus erythropus ; Engel 1930: 464, fig. 5.
Diagnosis. Abdomen spatulate ( Fig. 6); 12 very fine yellow apical marginal scutellar setae; epandrium strongly turned down apically ( Figs 10, 11, 12); hypandrium with acuminate projection with long yellow setae ( Figs 10, 11, 13).
Redescription. Male. Lectotype here designated. Head ( Fig. 4). Antenna dark brown ( Figs 3, 5), scape with yellow setae, pedicel with black setae; palpus brown, yellow setose; proboscis dark brown, yellow setose ventrally, labial setae yellow; occiput black, silver tomentose with white setae; 8–12 black postocular macrosetae.
Thorax ( Figs 2, 3, 5). Antepronotum and postpronotum black with white setae, yellow tomentose; mesonotum with ground color black dorsally, brown and yellow tomentose; posthumeral and postalar spots, lateroscutal stripes and pleuron silver tomentose, scutellum yellow tomentose. Chaetotaxy: 1 black and 1 yellow notopleural macrosetae; 1 yellow supra-alar macroseta; 1 yellow postalar macroseta; anatergal setae absent; 6 yellow dorsocentral macrosetae, 12 very fine yellow apical scutellar setae; katatergal macrosetae yellow; posterior meron + metanepisternum yellow tomentose, with row of yellow macrosetae and tuft of small yellow setae on posterior margin.
Wing ( Figs 6, 7). Brown hyaline; dark brown veins; with costal dilatation; crossvein r-m just before middle of cell d; R 4+5 bifurcation at level of apex of cell d; microtrichia on posterior wing margin arranged in single row; halter pale yellow, stalk base and bulb light brown.
Legs ( Figs 2, 8). Femora orange-yellow, apex brown; tibia yellow; hind tibia with brown apex; tarsomeres brown, except first tarsomere of fore and mid tarsi yellowish. Chaetotaxy: fore femur yellowish setose ventrally, apex with 2 black setae; mid femur yellow setose, with 3 black and 2 yellow macrosetae anterodorsally, 2 black setae dorsoapically; right hind femur with setae as follows: 9 macrosetae anteroventrally – 5 black apically, 1 yellow and 1 black medially, 2 yellow basally; 10 yellow small stout setae posteroventrally; 3 yellow macrosetae posterodorsally; 2 yellow and 2 black setae dorsoapically; left hind femur with 2 basal yellow setae posteroventrally and 7 black macrosetae posteroventrally; 4 yellow macrosetae anterodorsally; fore tibia with 3 long yellow setae posteriorly; mid tibia with 2 black ventral setae, 2 yellow posteroventral and 2 yellow anterodorsal setae; hind tibia with 4 black setae dorsoapically; tarsomeres largely black setose dorsally and yellow setose ventrally, first and third tarsomere of fore leg with 2 yellow setae, second tarsomere with 1 yellow seta.
Abdomen ( Fig. 6). Brown. Spatulate; yellow setulose, densely pale yellow tomentose, posterior margin of tergites light brown and without setulae; tergites with yellow, lateral marginal macrosetae, longer on lateral margins of tergites I and III; two lateral macrosetae on tergites IV–IX.
Terminalia ( Figs 9–13). Black, except for light brown cercus, gonocoxite and epandrium. Cercus truncate ( Fig. 9); epandrium strongly turned down apically ( Figs 10, 11, 12); epandrium with subapical projection and pointed apex ( Figs 9, 10, 12); hypandrium with acuminate projection with long yellow setae ( Figs 10, 11, 13); gonocoxite with digitiform projection at lateral margin ( Fig. 13).
Remarks. Ommatius erythropus is a typical species of the O. costatus species group. It has the following characteristics of this group: preapical, dorsoposterior seta on the mid femora; hind femora more slender, usually 5–6 times longer than wide in anterior view, row of posteroventral bristles not divided into two groups or separated by wide bare space; M 1 and M 2 veins slightly sigmoid ( Scarbrough 1993, 2008). Ommatius erythropus is similar to O. spatulatus Curran, 1928 , but differs by the presence of six yellow dorsocentral macrosetae, apical scutellar yellow setae and mid femur with a brown, moderately thick, preapical, dorsoposterior seta.By contrast, O. spatulatus does not have dorsocentral macrosetae, apical scutellar setae and the mid femur has a pale, long, thin, preapical, dorsoposterior seta. Furthermore, O. erythropus differs from O. spatulatus by the combined characters of the terminalia.
Lectotype condition. Thorax with a hole on posterior portion of scutum.
Type examined. Lectotype: Savañah/ erythropus, Coll. Winthem / Lectotype Ommatius erythropus . 1 male (NMW).
