Diagnosis.— The genus has a unique tegminal venation as discussed above. Apart from this it differs from Leptoderes by a more robust and in frontal view shorter head and by a rather short and stout pronotum, instead of an elongate pronotum with a laterally concave disc. The tibial tympana are conchate internally and are open on the external side.

Apart from the tegminal venation and the modified hind tibiae, the two new species are notable for their color polymorphism comprising two color variants, (1) a variant with striking pink and red-brown body color, with wings and legs contrasting with the pastel green tegminal veins and other marks of the same color and (2) a uniform green variant so far only observed in males. Color pattern of E. thaumasium have been described as ochreous buff with yellowish pattern (Hebard 1922), but this description was based on a dead female specimen whose color would have altered after death.
