Abstract

Description of three new species of katydids from Costa Rica (Orthoptera, Tettigoniidae)
Three new species of katydids from the Reserva Biológica Alberto Manuel Brenes (Alajuela) in Costa Rica (Central America) are described. The specimens were collected in the course of the Project INVARTRAB developed by the Central University of Costa Rica and the INIA de Madrid (España). The specimens were sampled by direct prospection on plants and light traps. The new species belong to the genera Phlugis, Scopiorinus and Viadana, respectively. Phlugis ramirezi n. sp. has little developed tegmens and wings, male tenth abdominal tergite ending in two spiniform processes, cerci curved with a basal spur, and four teeth in the apex. Scopiorinus estebani n. sp. shows male tenth abdominal tergite with a longer than broad expansion, subgenital plate depressed in the middle, and lateral spiniform processes at the end. Viadana rowelli n. sp. has rhomboidal tegmens and male cerci with an internal branch with serrulated apex inserted in the last third. Main characters are illustrated and compared in related species in each genus.
