Diagnosis. Recognized among species of Ommatides by males submacropterous with very short membrane just reaching past abdomen; dorsal lobe of expanded 1st labial segment with 10-12 short, stout setae; and 1 pair of short, proximal processes on 4th labial segment. Most similar to O. parvidentis sp. nov., but distinguished by dorsal lobe of 1st labial segment simple and beset with many short, stout setae.

Description. Male: submacropterous with very small membrane just reaching past abdomen; length: 1.32– 1.43 mm; body ovoid. COLORATION: overall color dark brown to black, except labium, legs, and stripes between costa and clavus yellow ( Fig. 1 ). SURFACE AND VESTITURE: dorsal lobe of expanded 1st labial segment with 10-12 short, stout setae; forefemur without anterior spicules; 2nd tarsomere of hind leg with 2 stout setae anteroventrally. STRUCTURE. HEAD: disc decurrent; dorsal lobe of 1st labial segment large; 2nd labial segment elongate; 3rd labial segment reduced to small sclerite on dorsal surface of labium; 4th labial segment shorter than 2nd segment and with one pair of short, proximal processes ( Figs 2 , 5 ). THORAX: ratio of pronotal collar length to pronotum length 0.24–0.31; collar not depressed below rest of pronotum ( Fig. 1 ); posterolateral margin of pronotum broadly and shallowly concave; postnotum rectangular with very slightly curved posterior margin and corners; ratio of height to length of forefemur 0.26–0.15; tarsal formula 3-3-3; ratio of length of hind tibia to width of pronotum 1.16–1.26; venation of submacropterous forewing as in Fig. 8 ; tc very flattened pentagonal; dc forming long parallelogram; An1 meets Cu. ABDOMEN AND GENITALIA: as in genus description ( Fig. 9 A,B ), with spiracle 8 set upon membranous tubercle of tergum 8 process. ( Fig. 6 ).

Female: submacropterous with very small membranes just reaching past abdomen; total length: 1.35–1.80 mm; body ovoid. COLORATION: overall color very light brown to brown, with brown patches near eyes, and pronotum and scutellum brown, and pale stripes between costa and clavus ( Fig. 1 ). SURFACE AND VESTITURE: labium as in generic description; forefemur without anterior spicules, but with one long setae on middle of anterior surface; 2nd tarsomere of hind leg with 2 stout setae anteroventrally. STRUCTURE. HEAD: as in generic description. THORAX: ratio of pronotal collar length to pronotum length 0.28–0.32; collar not depressed below rest of pronotum ( Fig. 1 ); posterolateral margin of pronotum broadly and shallowly concave; postnotum rectangular with very slightly curved posterior margin and corners; ratio of height to length of forefemur 0.18– 0.29; tarsal formula 2-2-3; ratio of length of hind tibia to width of pronotum 1.16–1.30; venation of macropterous forewing as in male, except membrane is slightly larger and rc3 divided into 2 cells. ABDOMEN AND GENITALIA: as in genus description ( Fig. 9 C,D ), except gonoplacs with wide, short lobes.

Etymology. Named after the collector of the holotype specimen, Matthew Yoder.

Distribution. Known from low elevation sites in Panama and Ecuador.

Macrohabitat and Collecting method: Tropical wet forest; Yellow Pan Trap.
