Description

Head: Scapus unarmed and 2.5 times as long as the pedicellus. Thorax. Pronotum: with two fairly short and laterally little-flattened spines. Both spines as long as fastigium. Metazonal spine in lateral view almost twice as wide as prozonal spine and with sharply pointed apex. Legs: fore femur cylindrical, armed with two ventral spinules. Fore tibia with square cross section and two dorsal spines below the tympanum, ventral margin with four spinules. Middle femur with three ventral spines; spines of middle tibia organized as follows: one on the ventrointernal margin and two on the ventro-external margin. Hind femur slender and laterally flattened, ventro-external margin armed with five well-developed spines, which increase in size from proximal to distal region, ventrointernal margin with four spines with the same characteristics as the previously mentioned ones. Tegmina apex truncated vertically. Abdomen tenth tergite without modification. Male cerci pilose, external branch sharply curved, internal branch with a denticulate plate on the apex.
