Viraktamath, C. A. & Webb, M. D., 2007, Review of the leafhopper genus Pythamus Melichar (Hemiptera: Cicadellidae: Evacanthinae) in the Indian subcontinent, Zootaxa 1546 (1), pp. 51-61 : 57-61

Onukia assamensis (Ramakrishnan) comb. nov.

Dussana assamensis Ramakrishnan 1989: 45–46 , Figs 1–11 . Holotype ♂, India: Assam [NPC, examined]

Material examined: India: Assam: Holotype ♂, Nagarjunka, 9.ix.1983, Mayaram & V. V. Ramamurthy, on weeds ( NPC).

Remarks: Examination of the type specimen revealed that the species is pale yellow with a black spot on the vertex, the median carina on the head is not raised, the male pygophore has long, slender ventral processes exceeding the pygophore and the aedeagal shaft has a large, elongate, basal hood-like process. These characters showed that the species does not belong to Pythamus but to Onukia Matsumura and hence the generic transfer.
