pronotum elongate, without a vertical posterior surface and the distance between the shoulder slightly less than the distance between one of them and the spiracle; marginalis not more than half as long as its distance from the basalis; antenna neither 14 segmented nor the flagellum thickened in the middle
pronotum not elongate, with a more or less vertical posterior face and the distance between the prominent dentiform shoulders not less than the distance between one of them and the spiracle; marginalis at least two-thirds as long as its distance from the basalis; either the antenna with 14 segments or the flagellum curiously thickened in the middle
