Family Delphacidae Leach, 1815

Subfamily Asiracinae Motschulsky 1863: 108.

Tribe Platysystatini Emeljanov, 1995

Genus Equasystatus Asche, 1983: 128.

Type species (in original combination): Punana breviceps Muir, 1926.

Distribution

Ecuador.

Recognized species

There is a single species in this genus.

Equasystatus breviceps (Muir, 1926) – Described from  a single male specimen from Ecuador (Naranjapata, 1,850 feet, Dec. 1922; Cumanda canton, Chimborazo Province).

Plant Associations

None.

Economic Importance

Limited.

Recognition

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).
