Subtribe Ommatolampidina

Comments. This subtribe is one of the most homogeneous in terms of external morphology. Its filiform antennae distinguish it; fastigium is subtriangular and does not noticeably extend beyond the scape and pedicel of the antenna (differentiating it from Vilernina and some Oulenotacrina , which have a more elongated fastigium and usually dorsoventrally flattened or ensiform antennae). The pronotum lacks conspicuous modifications (unlike Oulenotacrina , which exhibit lateral projections or median lobes in the prozona, particularly in genera associated with tree bark). Members of this subtribe are micropterous or subapterous, with ovoid or lanceolate, narrow tegmina, generally featuring conspicuous venation useful for distinguishing genera and species (differing from Oulenotacrina and Vilernina , where most taxa are macropterous or brachypterous and lack conspicuous markings on the tegmina). Their coloration is bright, with uniform shades ranging from gray to yellow and green (in contrast, Oulenotacrina and Vilernina exhibit cryptic coloration and sometimes camouflage among leaf litter or bryophytes).

This group was comprehensively reviewed by Carbonell & Descamps (1978), who described most of the genera and species currently included. The subtribe remained largely unstudied for a long time, with only recent additions and modifications. The generic name Albrechtia Carbonell & Descamps, 1978 , was replaced by Peruana Koçak & Kemal, 2008 , as it was a homonym of a previously described mollusk ( Koçak & Kemal 2008). Later, Costa et al. (2014) described Muriciacris Costa, 2014, a monotypic genus from the Brazilian Atlantic Forest, including chromosomal data. Subsequently, Cadena-Castañeda & Cardona-Granda (2015) reassigned Dicaearchus cribellatus Stål, 1878 , from Melanoplinae to Ommatolampidinae after studying additional specimens. Since the species was previously known only from a female, examining male specimens clarified its taxonomic placement.

Following these recent additions and changes within the subtribe, it is necessary to update the key to identify its genera.
