Remarks. Myrsidea v. ceciliae and M. v. brevicarinatus both were placed in synonymy with M. victrix by Price et al. (2003), but this study has shown that, while synonymous with each other, they are distinctly different from M. victrix . Both sexes of M. ceciliae have consistently fewer marginal metanotal and tergal I–III setae than M. victrix . Carriker [and Diaz­Ungria] (1961) recognized these differences, but felt they merited only subspecific status. Our study of type materials has suggested that these differences are of a magnitude deserving specific recognition. Other features given by Carriker as potential differences generally are a function of distortion in mounting or improper clearing of specimens. In none of Carriker's descriptions of toucan Myrsidea did he make special note of the conspicuous male genital sac sclerites. We agree with Carriker [and Diaz­Ungria] (1961) that M. v. brevicarinata is “most closely related to M. v. ceciliae .” He adds “At best, it is not an outstanding race, but seems worthy of recognition.” None of the features enumerated in his description enable separation.
