Bates (1880a) described Acanthoderes crocostigma based on a single female from Ecuador and reported: “By the structure of the antennae, this species would belong to the genus Scleronotus , but all the other characters of the insect are those of Acanthoderes . ”

Martins & Galileo (1996) described Acakyra to include their new species A. iaguara , from Colombia. The authors characterized Acakyra based especially on antennomere III tumid apically, without tuft of long setae,antennomere IV without modifications, the remaining antennomeres very short, and by the absence of dorsal carina on the elytra. Later, Martins & Galileo (2001) described A. nigrofasciata and A. laterialba , and Chemsak & Hovore (2002) described A. ocellata ocellata , and A.ocellata onca . The three later species (see photographs on Bezark, 2021) have a centrobasal crest and moderately distinct elytral carina. Therefore, the only reliable feature, allowing recognition of species of Acakyra , is the distinctly short length of antennomeres V-VII, a feature not present in Aegomorphus . As Acanthoderescrocostigma has these antennomeres distinctly short, the species is herein transferred to Acakyra . The general appearance of A. crocostigma is similar to that of A. iaguara , A. ocellata ocellata and A. ocellata onca .
