Emended Diagnosis: As given by Chopard (1969) and Otte (1987). Harp on FW with 3–4 oblique veins

Head. Globular, ocelli in frontal view forming a triangle, middle area of ocelli, vertex and occiput dark brown in color, while frons and genae yellowish brown ( Fig. 4E ). Head much wider than long in dorsal view ( Fig. 4D ). Face deeper than broad in frontal view ( Fig. 4E ). Occiput rounded in lateral view and with 6 yellow bands; of which, 2 broad marginal bands and middle 2 connected with thin yellow lines having inverted V-shape ( Fig. 6C ). Median ocellus ellipsoidal and larger than lateral ocelli. Fastigium is slightly convex or flat in dorsal view and twice wider than scape. Maxillary palpi yellowish; 3 rd and 4 th segment sub equal in length; 5 th segment longest with distal margin strongly slanting ( Fig. 2F ).

Pronotum. Lateral margin of pronotum straight and slight ascending posteriorly ( Fig. 2C ).

Wings. FW variable in length, not extending beyond the abdomen. HW may or may not be present; when present, longer than FW in both sexes. Mirror almost 1.5 times wider than long, anterior angle obtuse, harp with 3–4 oblique veins, diagonal vein either straight or S-shaped, apical field short to long. Lateral field of FW with 6–10 longitudinal veins. Legs: TI with 3 unequal apical spurs, TII with 4 apical spurs and TIII with 3 pairs of apical spurs.

Male genitalia. Pseudepiphallic lobe with terminal finger-like process or styli, ectoparameres with strong serrations and made up of 2–3 lobes.

Female genitalia. Copulatory papilla sclerotized; posterior end with bulbous shape.
