Armasius iberianus (Orthoptera: Tetrigidae: Cladonotinae): a new genus and species of pygmy grasshoppers from eastern Cuba

Abstract

The new genus and its type species Armasius iberianus, a remarkable cladonotine tetrigid, are described based on a single individual collected from Monte Iberia, Guantánamo Province, in eastern Cuba. Armasius is characterized for having a large pronotum flattened on top to a thin crest that is uniformly elevated only about half the body height, the pronotum covers the whole abdomen, narrowing posteriorly, and turning upwards at its posterior end. A character not yet seen in any other Antillean Cladonotinae is that the posterior angles of the lateral lobes of the pronotum project laterally, flattening to form a horizontal triangular spine.
