Introduction

This genus is remarkable in the structure of the antennae with the numerous sensoria of the second segment protruding beyond the surface of the segment to give the segment a "coralloid appearance" (Kirkaldy 1906). Distant's (1906) description of Devadanda stated that the antennal joints beyond the second segment were prominently produced "bearing very long pectinations" and this was accompanied by a illustration. Muir (1917), in synonymising the two generic names, discounted Distant's (1906) description as being a condition "not found in the Derbidae or in the Fulgoroidea". Nonetheless, the antennal structure is remarkable. The head is also extremely laterally compressed so that it can be almost transparent in lateral view. The genus contains about a dozen described species from SE Asia with a single species in the wet tropics of North Queensland.

Diagnosis

Head produced more than their length in front of eyes; vertex and frons somewhat confused, the former excavated as far as anterior margin of eyes, lateral margins acute and converging, meeting at anterior margin of eyes, continuing thence (somewhat nutantly) practically contiguous, as far as clypeus. Antennae large but short, with enormous sensory organs, giving the antennae a coralloid appearance. Pronotum carinate medianly, rectangularly emarginate, laterally subfoliaceous. (Kirkaldy 1906)
