Wings hyaline with black spot at apex of forewing; veins and stigma black. Head: Lower interocular distance shorter, about 0.8X, eye height; malar space about 0.2X eye height ( Fig. 128). Occipital carina narrow, less than a fifth diameter of an ocellus. From above, straight then roundly narrowing behind eyes, distance behind eyes about 0.7 eye length ( Fig. 129). Front ocellus in distinct depression ( Fig. 128). Head smooth and shining, vertex and gena with widely spaced punctures, interspaces much longer than puncture diameters; frons with widely scattered somewhat larger punctures, separated by distances more than puncture diameters, interspaces with fine microsculpture ( Figs 128, 129).  Mesosoma: Pronotumwithout anteriorly projecting tooth. Propleuron shining, almost impunctate. Mesonotum shining, without sculpture on front downturned portion of mesoscutal middle lobe, with coarse transverse carinae dorsally; pronotum almost impunctate, large smooth shining area at center, slight reticulations on posterior margin; mesopleuron almost impunctate, microsculptured with some large reticulations ventroanteriorly and dorsoposteriorly; metapleuron microsculptured with 5 or 6 carinae ventrally; propodeum microsculptured but more reticulate around metasomal insertion and posteriorly ( Figs 130, 131). Hind coxa long, about 3.3X longer than broad, smooth and shining. Tarsal claws with 4 teeth. Forewing with cells 1M and 1Rs separated by long Rs+M vein (as in Fig. 91).
