Identification. Adult A. affinis can be distinguished from other Apogo n species by the combination of cycloid to weakly ctenoid scales, median predorsal scales present, pectoral-fin soft rays 11 or 12 (rarely 13), nine segmented anal-fin rays, and both jaws with a single series of small conical teeth interspersed with several enlarged caniniform teeth (Böhlke & Chaplin 1993, Gon 2002). Two adult specimens identified as A. affinis based on those features were analyzed genetically (Appendix 1). The specimens were taken in trawls and are not in good shape, and we selected a photograph of an adult not analyzed genetically in this study to illustrate the species (Fig. 20). No larvae or juveniles analyzed in this study genetically match A. affinis.
