Diagnosis. Recognized among species of Ommatides  by males and females submacropterous with very reduced membrane not reaching tip of abdomen; the male with dorsal lobe of the dorsally expanded 1st labial segment with 10 short, stout setae on the dorsal edge and 2 large, stout setae on at tip of smaller lobes at the tip of the large lobes; 1 pair of short, proximal processes on 4th labial segment; females with 5 setae between the 2 proximal most teeth of left anterior gonapophysis, and 4 setae between the 2 anterior most teeth of right anterior gonapophysis. Most similar to O. yoderi  sp. nov., except for dorsal lobe of 1st labial segment large and beset with smaller lobes ( Fig. 5View FIGURE 5).

Description. Male: submacropterous with very reduced membrane not reaching tip of abdomen; total body length: 1.31–1.73 mm; body ovoid. COLORATION: body light to dark brown; legs mostly yellow with brown apical half of mid-tibia ( Fig. 1View FIGURE 1). SURFACE AND VESTITURE: dorsal lobe of 1st labial segment with 10 short setae along dorsal edges and 2 large setae on smaller lobes at tip of large lobes; forefemur without anterior spicules; 2nd tarsomere of hind leg with stout 2 setae anteroventrally. STRUCTURE. HEAD: disc declivous; dorsal lobe of 1st labial segment large, sinuate in lateral view with pronounced distal secondary lobe ( Figs 2View FIGURE 2, 5View FIGURE 5); 2nd labial segment elongate; 3rd labial segment represented by small dorsal sclerite; 4th labial segment with 1 pair of short, proximal processes ( Fig. 5View FIGURE 5). THORAX: ratio of pronotal collar length to pronotum length 0.23–0.32; posterolateral margin of pronotum shallowly and broadly concave; collar depressed below rest of pronotum ( Fig. 1View FIGURE 1); postnotum long and curved; ratio of height to length of forefemur 0.17–0.29; tarsal formula 3-3-3; ratio of length of hind tibia to width of pronotum 1.03–1.30; venation of short thickened submacropterous forewing as in Fig. 7View FIGURE 7; tc short pentagonal; dc long triangle; An1 meets Cu; Cu forming 2 right angles; distal portion of wing beyond An1 short. ABDOMEN AND GENITALIA: as in genus description ( Fig. 9 A,BView FIGURE 9), with spiracle 8 set upon membranous tubercle of tergum 8 process ( Fig. 6View FIGURE 6).

Female: macropterous with very reduced membrane not reaching tip of abdomen; total body length: 1.68 mm; body ovoid. COLORATION: as in male. 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 0.21; collar depressed below rest of pronotum; posterolateral margin of pronotum somewhat narrowly and shallowly concave ( Fig. 1View FIGURE 1); postnotum shape unknown; ratio of height to length of forefemur 0.24; tarsal formula 2-2-3; ratio of length of hind tibia to width of pronotum 1.20; venation of macropterous forewing as in male. ABDOMEN AND GENITALIA: as in genus description ( Fig. 9 C,DView FIGURE 9), with 5 setae between the 2 anterior most teeth of left anterior gonapophysis, and 4 setae between 2 anterior most teeth of right anterior gonapophysis.

Etymology. Combination of Latin adjective “parvus” meaning “small” and noun “dens, dentis” meaning “tooth”. Named for the short, stout setae on the dorsally expanded 1st labial segment.

Distribution. Known from lowland rainforest in both Peru and Guyana, suggesting that this species has a very wide distribution range.

Macrohabitat and Collecting method: Primary and tropical Rainforest; Flight Intercept Trap, Sifting Leaf

Litter, and Yellow Pan Trap.
