Introduction
This pale brown species is common, widespread and variable, usually brachypterous although macropters are reasonably common. The species differs from other species of Horouta by the arrangement of the preapical processes of the aedeagus, although some minor variation is noted in the disposition of the distal pair relative to the aedeagal shaft. In lateral view, the basal pair does not overlap the more distal pair as in H. aristarche.

Diagnosis
Pale yellowish testaceous. Eyes blackish grey. A minute black spot at side of last tergite, and two almost contiguous black-brown spots on the preceding tergite. Sternites and pleurites spotted with blackish brown. \'ertex distinctly longer medianly than at eyes, triangularly rounded in front, margin in front of eyes straight; vertex somewhat flat, a large rounded depression on each side of the middle line. Clypeus as wide anteriorly as frons posteriorly, which very gradually widens at clypeus, extending anteriorly beyond base of clypeus, posteriorly nearly touching margin of genae. Pronotum short, scarcely twice as broad as long, anteriorly arched, posteriorly slightly emarginate, sides very short. Tegmina short, reaching only to half the length of the abdomen, without appendix ; venation very obscure, but I think there are five discoidals. Clavus nearly as large as the apically rounded corium. Wings minute. Length 2 1/3 mm. (Kirkaldy 1906).
Brachypterous or macropterous. Colour variable, testaceous with or without pale or dark brown markings or pale dorsally and dark brown to black ventrally. Tegmen of macropters pale translucent with dark brown margins to cells. Tegmen of brachypters evenly testaceous translucent or brown with testaceous veins. Male genitalia: aedeagus with two pairs of processes, the proximal being slightly over half length of distal processes. (Fletcher 2004).
