Eleusima

Type specimen: Eleusima platysoma .

Description: Extremely depressed in dorsoventral direction; head without supraocular groove; at least three times wider than long with large prominent eyes; postocular sides directly narrowed behind eyes to wide neck; clypeus separated from vertex; deepened against vertex; pronotum extremely narrowed from middle to posterior angles; posterior margin less than half as wide as anterior margin; sides interrupted by short tooth; without grooves or deeply depressed punctures at anterior margin; sides of elytra divergent posteriad; abdomen wide and short; middle segments IV to VI wider than abdominal segment III.

The genus can be easily separated from the related genera Eleusis , Zeoleusis and Renardia by the stout, extremely depressed body. The supraocular grooves are also absent in Zeoleusis and Renardia , but species of these genera are much more elongate. Moreover, the wide head and the extremely narrowed pronotum are not found in these genera. The aedeagus also has specific characters. In Eleusis , Zeoleusis and Renardia the aedeagus is depressed in lateral direction as adaptation to its half rotation. In Eleusima the aedeagus is dorsoventrally depressed without rotation.
