Del carnaval al estereoscopio: Zeromastax (Orthoptera: Eumastacidae), un nuevo género de saltamontes payaso

Abstract

The identification in eumastacids is based on the study of genitalia; however, Zeromastax selenesii n. sp., belonging to the new genus Zeromastax, presents characters that easily differentiate it from the other eumastacids. The new taxon is characterized by the following combination of characters: (1) ten antennal segments, (2) spine in the ventral part of the posterior femur, (3) moveable spur in the distal-posterior part of the tibia, (4) micropterous, and (5) subepiphallic sclerite. The new genus is an intermediate between the families Eumastacidae and Episactidae, due to the presence of the subepiphalic sclerite.
