About Otiocerus wolfii Kirby, 1821
Otiocerus wolfii Kirby, 1821 can be distinguished from other Otiocerus species with overlapping ranges by a set of key features. It has no red markings on its forewings, which separates it from O. coquebertii, O. reaumurii, and O. stollii. It has a red stripe on the lateral side of its head, which distinguishes it from O. francilloni and O. abbotii. It bears a solid line on its forewing, which differentiates it from Otiocerus kirbyii, which has unicolorous wings. The only species that requires closer comparison is Otiocerus amyotti: O. amyotti can be told apart from O. wolfii by the absence of a small stripe on the side of the head that connects the apex of the head to the red stripe in O. wolfii, and by the fact that the stripe on the tegmina of O. amyotti reaches the apical margin of the tegmina, rather than ending at the apical part of the sutural margin as it does in O. wolfii.
