Canthon (Glaphyrocanthon) subhyalinus Harold, 1867

Canthon subhyalinus Harold 1867b: 79 Note 1. Two presently recognized subspecies of Canthon (Glaphyrocanthon) subhyalinus have been described, one of which may occur in the research area. The other one is C. (G.) subhyalinus subhyalinoides Balthasar, 1939 (recorded from Ecuador).

Note 2. Vaz-de-Mello and Cupello (2018b: 65) consider C. quadrimaculatus to be a valid species. According to Vaz-de-Mello (F. Vaz-de-Mello, pers. comm. 2018), they have come to this conclusion based on examinations of the type specimens of both C. quadrimaculatus and C. subhyalinus . They have chosen not to explicitly mention this revalidation as they consider it irrelevant, given that revalidations from subjective synonyms are not nomenclatural acts and thus not formally governed. These taxa are currently under revision (M. Cupello, pers. comm. 2018). We have elected not to follow the revalidation of the name C. quadrimaculatus by Vaz-de-Mello and Cupello (2018b) because of the absence of any listed distinguishing characteristics.
