Description de Maa (1963) :
Crown rather short when viewed vertically to its plane, median length about 1.5 X side length. Postclypeus strongly convex, moderately protruding forward, Pleurostome slightly broader than lorum. Bye large, as broad as tylus, nearly as long as broad when viewed vertically to plane of crown. Tylus distinctly broader than its distance to eye, Interocellar distance 1/2 of ocello-ocular distance. Pronotum distinctly broader than head; median carina wanting; anterolateral margin almost entirely carinated, slightly shorter than breadth of eye, about 2/5 as long as posterolateral margin, anteriorly hardly reflexed ; posterolateral margin slightly, and posterior margin deeply sinuate, Scutellum slightly broader than interocular distance. Tegmen transparent; veins fairly distinct, basally more or less weak; venation simple; R + M only 2/7 as long as corium; abscissae 1 of Rand M short, subequal in length ; R with 4-5 short crossveins near apex and extending to costal margin; R, M and Cu shortly bifurcate at apex, forming together 3 very short, depressed, apical cells (preapicals entirely merged into apicals); Cu joining M by a very short crossvein at point of basal 1/3, thence strongly converging to claval furrow at middle; clavus apically broadly rounded; 1A joining 2A by a crossvein near middle, forked at apex; corial appendix 1/3 as long as broad, slightly shortened at posterior portion; claval appendix isogonally subtriangular, acute at apex, Apical 1/3 of tegmina, when closed, folding beyond claval apex and overlapping each other to coyer abdominal apex; in profile, this apical 1/3 about 60' to horizontal plane.
