Material. Type material. Holotype, 1 male slide-mounted in Canada balsam, PERU: Manu : Pillcopata: Villa Carmen ACCA, trails 1/5/7, 12.88778°S 71.40194°W, 515 m, 25 Nov 2011 – 26 Nov 2011, Heraty, Weirauch, Portillo, Yellow Pan Trap (ED_0412) (UCR_ENT 00086134) (MUSM).

Diagnosis. Recognized among species of Ommatides by males submacropterous with small membrane not reaching tip of abdomen; dorsal lobe of 1st labial segment with apex rounded and with many (~22) short, stout setae; 4th labial segment without armature; abdominal spiracle 8 set upon membranous tubercle of tergum 8 process. Most similar to O. pristis sp. nov. in the lack of armature on the 4 th labial segment, but distinguished by being submacropterous, and by the state of spiracle 8.

Description. Male: submacropterous with short membrane not reaching tip of abdomen, length: 1.67 mm; body ovoid. COLORATION: wings and pronotum dark brown; vertex of head yellow; body brown; legs yellow ( Fig. 1 ). SURFACE AND VESTITURE: dorsal lobe of expanded 1st labial segment with many (~22) short, stout setae; 4th labial segment without armature; forefemur without anterior spicules; 2nd tarsomere of hind leg with 2 stout setae anteroventrally. STRUCTURE. HEAD: disc decurrent anteriorly; 1st labial segment strongly expanded dorsally, apex rounded; 2nd labial segment elongate; 3rd labial segment short; 4th labial segment slightly longer than 3rd and unarmed ( Fig. 5 ). THORAX: ratio of pronotal collar length to pronotum length 0.29; collar depressed below rest of pronotum ( Fig. 1 ); posterolateral margin of pronotum somewhat broadly and shallowly concave; postnotum unknown; ratio of height of forefemur to length of forefemur 0.25; tarsal formula 3-3-3; ratio of length of hind tibia to width of pronotum 1.33; venation of submacropterous forewing as in Fig. 7 ; tc nearly rectangular; dc shaped like a long parallelogram; An1 meeting Cu. ABDOMEN AND GENITALIA: as in genus description ( Fig. 9 A,B ), with abdominal spiracle 8 membranous and separated from sclerotized tergum 8 process ( Fig. 6 ).

Female: unknown.

Etymology. Patronym derived from the type locality, Pillcopata, of the holotype and only known specimen.

Distribution. Only known from the type locality in the foothills of the Andes in Pillcopata, Peru.

Macrohabitat and Collecting method: Tropical rainforest; Yellow Pan Trap
