Abstract

PORRAS, Mitzy F.. From the carnival to the stereoscope: Zeromastax (Orthoptera: Eumastacidae), a new genus of clown grasshoppers . Rev. Colomb. Entomol. [online]. 2007, vol.33, n.1, pp.70-73. ISSN 0120-0488.

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.

Keywords : Genitalia; Subepiphallic sclerite; Colombia; Coloration pattern; Neotropics.
