Material. Type material. Holotype, male, slide-mounted: ARGENTINA, Formosa, Estancia “La Marcela”, 35 km east. El Colorado , [43.716667 S, 71.2 W, 844m], VIII-2003; collector J. Williams; Light trap, MLP accession no. 5316 (MLP).

Diagnosis. Recognized among species of Ommatides by males being macropterous with long membrane; lobe of dorsally expanded 1st labial segment with pair of mesal and ventral pair spines and an irregular series of minute sclerotized teeth distally; pair of long, blunt processes with serrated apices occupying proximal end of extended 4th labial segment and a pair of small tapered processes occupying medial portion of 4th labial segment; and 3rd labial segment reduced to small sclerite on dorsal surface of labium. Most similar to O. tridentis sp. nov. and O. duodentis sp. nov. in the elaborate armature on labial segment 4, but distinguished by the proximal processes of the 4th labial segment being straight, the apices blunt and beset with serrated spines.

Re-Description. Male: macropterous with long membrane; total body length: ~ 2.46 mm; body ovoid. COLORATION: unknown. SURFACE AND VESTITURE: 1st labial segment with pair of internal proximal spines and irregular series of minute sclerotized teeth distally; anteriorly forefemur with 9 spicules; hind tibia with 6 erect medium-length stout setae ventrally on distal half; 2nd tarsomere of hind leg with at least 1 stout seta anteroventrally. STRUCTURE. HEAD: lateral view unknown since specimen is slide-mounted; pair of long, blunt processes with serrated apices occupying extended 4th labial segment; 3rd labial segment reduced to small sclerite on dorsal surface of labium. THORAX: ratio of pronotal collar length to pronotum length 0.20; shape of posterolateral margin of pronotum unknown; postnotum long and slightly curved on lateral margins; ratio of height of forefemur to length of forefemur 0.28; tarsal formula 3-3-3; ratio of length of hind tibia to width of pronotum 1.08; venation of long macropterous forewing as in Fig. 7 ; tc long pentagonal; dc tapering rectangle; rc forming very long, thin rectangle; An1 meets Cu; Cu slightly curvy or zigzaggy (different on right and left wing); posterior portion of wing below An1 large. ABDOMEN AND GENITALIA: as in genus description ( Fig. 9 A,B ), with position and state of spiracle 8 unknown (not seen in photo as associated with tergum 8 process) ( Fig. 6 ).

Female: unknown.

Distribution. Only known from the type locality in Formosa, Argentina.

Macrohabitat and Collecting method: Scrub; Light trap.
