Description.
Male. BOdy medium-sized. Fastigium verticis narrOw, slOping anteriOrly, furrOwed dOrsally, separated frOm fastigium frOntis by a gap. PrOnOtum with disc slightly flattened in pOsteriOr area, lateral angles appreciably cOnstricted befOre the middle, then gradually expanding backwards, anteriOr margin slightly cOncave, pOsteriOr margin rOunded, median carina weak, principle transverse sulcus V-shaped; lateral lObes distinctly lOnger than deep, anteriOr margin prOximately straight, ventral and pOsteriOr margins mOderately rOunded; humeral sinus distinct.
Tegmina surpassing apices Of pOstfemOra, and brOader than the length Of prOnOtum, apices brOadly rOunded; radius sectOr branching slightly befOre the middle Of tegmina and with 4 branches behind apical third Of Rs, withOut Other stems behind Rs On radius (

lOng, slightly curved in basal third, with abOut 96 teeth, Of which 10 teeth widely spaced in basal area, Other teeth densely arranged in central and apical areas (
