Material. Type material. Holotype, 1 male, SURINAME: Para: Zanderij, near Guesthouse , 5.45139°N 55.21667°W, 15m, 0 7 Feb 2010 – 09 Feb 2010, P. Skelley, W. Warner, C. Gillett, Light Trap, 1 male (UCR_ENT 00011930) (FSCA).

Diagnosis. Recognized among species of Ommatides by males submacropterous with membrane reduced and just reaching tip of abdomen; the males with dorsal lobe of the 1st labial segment large and with many short, stout setae; 4th labial segment unarmed. Most similar to O. insignis Uhler , but distinguished by proximal half of forewing mostly dark with pale border along claval suture, and dorsal lobe of 1st labial segment in lateral view extending from head as rounded lobe.

Description. Male: submacropterous with membrane reduced and just reaching tip of abdomen; length: 1.24 mm; body ovoid. COLORATION: Overall dark brown to black, except labium, leg, and stripes between costa and clavus yellow ( Fig. 1 ). SURFACE AND VESTITURE: dorsal lobe of the 1st labial segment with many 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 and 4th labial segments short and of about same length ( Figs 2 , 5 ). THORAX: ratio of pronotal collar length to pronotum length 0.21; collar depressed below rest of pronotum ( Fig. 1 ); posterolateral margin of pronotum narrowly and shallowly concave; postnotum shape unknown; ratio of height to length of forefemur 0.17; tarsal formula 3-3-3; ratio of length of hind tibia to width of pronotum 1.00; venation of macropterous forewing as in Fig. 8 , tc short pentagonal; dc long thin rectangle; 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,B ), state of tubercle of tergum 8 process and position of spiracle 8 unknown ( Fig. 6 ).

Female: unknown.

Etymology. Patronym based on the type locality Zanderij in Suriname.

Distribution. Only known from the type locality in Suriname.

Macrohabitat and Collecting method: Low elevation wet forest; Light Trap.
