Diagnosis. Recognized among species of Ommatides   by both males and females being macropterous with long membrane extending just past tip of abdomen; males with the lobes of the dorsally expanded 1st labial segment with ~8 short, black setae on either side of the labial groove and 1 longer, apically expanded, light-colored seta submedially; 4th labial segment with 2 pairs of processes, proximal processes lateral, long and slightly curved, with apices acute, distal processes dorsolateral and short; 3rd labial segment dorsally only represented by small sclerite; spiracle 8 set upon fully sclerotized tubercle of tergum 8 process. Most similar to O. ornatus   and O. tridentis   sp. nov., but distinguished by proximal processes of 4th labial segment slightly curved, and apices acute.

Description. Male: macropterous with large membrane extending just past tip of abdomen; total body length: 1.94 mm; body elongate ovoid. COLORATION: head, pronotum, and forewings mostly brown; labium yellow; processes and tip of labium black; area surrounding claval suture pale; scutellum dark brown; legs mostly yellow with black tarsi; and genital capsule and genitalia tan to dark brown ( Fig. 1 View FIGURE 1 ). SURFACE AND VESTITURE: lobes of dorsally expanded 1st labial segment submedially with 1 longer, apically expanded, light-colored seta and ~8 short, black setae on either side of labial groove; forefemur anteriorly with row of 7 spicules and 1 single long, stout seta; 2nd tarsomere of hind leg with 2 stout seta anteroventrally. STRUCTURE. HEAD: disc declivous anteriorly; dorsal lobe of 1st labial segment large, dorsally pointed in lateral view ( Fig. 2 View FIGURE 2 ); 2nd segment elongate; 3rd labial segment represented by small lateral sclerite; 4th labial segment with 2 pairs of processes, proximal processes lateral, long and slightly curved, with apices acute; distal processes dorsolateral and short. THORAX: ratio of pronotal collar length to pronotum length 0.24; posterolateral margin of pronotum somewhat deeply and somewhat narrowly concave; ratio of height to length of forefemur 0.30; tarsal formula 3-3-3; ratio of length of hind tibia to width of pronotum 1.17; venation of macropterous forewing as in Fig. 7 View FIGURE 7 ; Cu relatively straight; rc2 triangular; dc1 5-sided; cub longer than rc; rc longer than dc; and dc longer than bc. ABDOMEN AND GENITALIA: as in genus description ( Fig. 9 A,B View FIGURE 9 ), with fully sclerotized spiracle 8 associated with tergum 8 process ( Fig. 6 View FIGURE 6 ).

Female: macropterous with membrane reaching tip of abdomen; total body length: 1.53–1.75 mm; body elongate ovoid. COLORATION: as in male ( Fig. 1 View FIGURE 1 ). SURFACE AND VESTITURE: labium as in generic description; vestiture on legs as in male. STRUCTURE. HEAD: as in generic description. THORAX: ratio of pronotal collar length to pronotum length 0.18–0.23; collar depressed below rest of pronotum ( Fig. 1 View FIGURE 1 ); postnotum subrectangular; posterolateral margin of pronotum deeply and somewhat narrowly concave; ratio of height to length of forefemur 0.18–0.25; tarsal formula 2-2-3; ratio of length of hind tibia to width of pronotum 0.81–0.95; venation of macropterous forewing as in male. ABDOMEN AND GENITALIA: as in genus description ( Fig. 9 C,D View FIGURE 9 ), with spiracle 8 set upon fully sclerotized tubercle of tergum 8 process ( Fig. 6 View FIGURE 6 ).

Etymology. Named for the two pairs of processes on the labium, combining Latin duo meaning “two” and dentes meaning “teeth”.

Distribution. Currently only known from low elevation sites across Colombia.

Macrohabitat and Collecting method: Amazonia rain forest and flood forest; Malaise Trap.
