Economic Importance



This genus erected by Barringer and Bartlett (2011).

Features of this genus are 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.

Pentasteira can be separated from other Platysystatini by this key, extracted from Barringer & Bartlett (2011) with the first couplet of Ashe & Webb’s (2013) key added to separate Pichinchana.

1. Frons with simple median carina or median carina vestigial; distinct setae on veins over the entire tegmina … 2
1′. Frons with median carina narrowly forked from near its base; distinct setae on tegmina only at margin distally of nodal line… Pichinchana

2. Antennae terete in cross-section; frons in frontal view convex between eye and laterally projecting beneath eyes to cover (or nearly cover) the base of scape; Brazil …  Platysystatus
2’. Antennae flattened in cross-section; frons in frontal view not (or weakly) convex and weakly projecting laterally beneath eyes, not covering base of scape … 3

3. Intermediate carinae of mesonotum serpentine, frons laterally rounded, aedeagus with stout flagellum; body color light brown mottled with pale, lacking broad white stripe on frons …  Equasystatus
3 ’. Intermediate carinae of mesonotum uniformly arched, frons peltate, aedeagus with fine flagellum; body deep brown with broad white stripe along frontoclypeal suture … Pentasteira
