Plant Associations


Economic Importance



This genus erected by Asche (1983), who separated this genus the old world genus Punana Muir, 1913.

The very wide and short vertex, separated from the frons with a carina, and the 5 carinate mesonotum (with intermediate carinae serpentine) are features of the tribe.

Equasystatus is very similar to Platysystatus and best separated by antennae flattened in cross-section (terete in Platysystatus); frons in frontal view weakly convex and weakly projecting laterally beneath eyes, not covering base of scape (convex between eye and laterally projecting beneath eyes to cover – or nearly cover – the base of scape in Platysystatus).
