Redescription

Content:  Frontal fastigium small, vertexial fastigium moderately deflexed and dorsomedially sulcate; pronotal carinae elevated and acutely angled, raised into three prominences anterior to the black marking and crenulated within the marking; pronotal lobes much deeper than wide, disc transversely sulcate two-thirds back; tympanal aperture anteriorly 20-30% and posteriorly 40% of tibial width; posterior margin of tegmen rounded distally (Fig. 16). Male stridulatory file about 6 ½ mm in length (Fig. 16 and 86) with about 180 apparently functional teeth spaced styliform processes articulated; cerci terminating in a pair of dissimilar blunt spines. Female nongenitally similar; ovipositor upturned through 65 degrees, apically pointed.

Mean size.– Male, total length 75 mm, tegmen 61 x 19, metatibia 33; female, 85, 69 x 24, 36, ovipositor 6. The Peruvian and Bolivian populations are uniform but the known specimens from Colombia (corrugate Hebard) are 20% smaller.
