Balthasar (1939) described Canthon angustatus ohausi (type locality: Ecuador) as a variety of Canthon angustatus Harold, 1867 (type locality: Costa Rica), which made the former name available as a subspecific category (see ICZN 1999, Articles 45.6.4 and 46.6.4.1). However, upon examining the external and genital morphology of the type specimens of C. angustatus ohausi (lectotype ♂ here designated, deposited at the NMPC, Plate 56D) and C. angustatus (lectotype ♂ here designated, deposited at the MNHN, Plate 56C), specifically, the differences in the aedeagus and the shapes of the pronotal spots, we think that they belong to two distinct species. Therefore, maintain ing the subspecific name originally proposed by Balthasar, we elevate it to species level under the following new status: Canthon (Glaphyrocanthon) ohausi Balthasar, 1939 stat. n. The lectotype is here designated and illustrated (♂ Plate 56D) and originates from Mera, Ecuador (associated with Amazon forests).
