This genus was effectively unrecognized prior to 1983, although Mound (1974) and Haga (1975) provided accounts of several species under the name Pyrgothrips . The species of Ophthalmothrips are essentially similar in structure to some species of Elaphrothrips but are distinguished by the ventrally prolonged compound eyes.

Diagnosis. Medium to large sized species, body slender, and macropterous, brachypterous or micropterous. Head elongate, usually with preocular projection; interocellar and postocular setae usually developed; cheeks subparallel with short setae, usually weakly constricted basally. Eyes distinctly prolonged posteriorly on ventral surface. Antennae eight-segmented; elongate; segment III with two sense-cones, IV with four. Mouth-cone short and rounded; maxillary stylets V-shaped and relatively low in head. Pronotum usually shorter than half the length of head; setae on anterior margin usually short, epimeral setae usually developed; notopleural sutures complete. Fore tarsal tooth present or absent in both sexes. Basantra present, ferna developed; prospinasternum and mesopresternum developed. Metanotum usually weakly sculptured with polygonal reticulation; metathoracic sternopleural sutures absent. Pelta usually triangular ( Figs 11 , 17 ) or hat-shaped ( Figs 9, 10 ) in a few species; abdominal tergites II to VI each with two pairs of sigmoid or not sigmoid wing-retaining setae ( Figs 5, 10 ); tergite IX setae S1 and S2 well developed. Tube shorter than head.
