Diagnosis. Redescription. Female and male. General appearance fusiform and convex. Head. Short, as wide as the anterior margin of the pronotum; antennae more than twice the total length of the body; fastigium in frontal view ( Fig. 2 a) with two parallel lobes, their apices rounded and each one as wide as the first antennal segment; frons narrow, between the widely separated antennal sockets semi-oval; eyes round, laterally protruding and oriented upward; fourth segment of maxillary palp (counting from the base) less than half the length of the third segment, and around 1/3 the length of the fifth, this last one with claviform tip. Thorax. Pronotum surface smooth, prozona ( Fig. 2 b,c) with three rounded spines, two median and two lateral, the first one less than half as long as the other two. Mesozona with four spines, two on each side, with similarly rounded tips; metazona with three spines, one in the middle and two on each side; metathorax with one long median spine and a small dorsally-oriented tubercle on the hind margin; meso- and metasternum with two spines on each side. Legs. Very long and slender, femora with stout spines; hind femur in males 1.5 times and in females 1.1 times as long as the total body length ( Fig. 2 d); all tibiae with minute spines. Abdomen: first and second tergite with one spine on the posterior margin, each spine less than half as long as the metatorax. Genitalia. Supra-anal plate very short; male subgenital plate ( Fig. 2 e,g) with broad base, three lateral lobes and narrowed toward the posterior end, finishing in two rounded lobes; cercus short and lanceolate, (Fig. f). Ovipositor slightly curved 1/10 the total body length.
