Neohermes angusticollis

Neohermes angusticollis

Neohermes inexpectatus

Neohermes inexpectatus

Identification: Dark markings in forewing indistinct and distant or reduced along the longitudinal veins; distinguished from similar Protochauliodes by the crossvein beyond posterior Rs branch fork of the forewing. Described from material collected d
