Taxonomy from Murray & Wilson 2008. Diagnosis for the species from Murray & Wilson 2008, p. 431: "A macrosemiid fish differing from all others by the high number of scales laterally along the body (68, compared to 50 or less in the other genera) and the greater number of dorsal fin rays (about 47 total) than in any other macrosemiid genus (dorsal rays numbering fewer than 40). Dorsal fin separated into two lobes, as in Notagogus, Histionotus, Propterus and Macrosemiocotzus, but unlike the continuous dorsal fin of Enchelyolepis, Macrosemius, and Legnonotus. Squamation consisting of rhomboid scales with a smooth posterior border, unlike the rhomboid scales of Macrosemius, Propterus, Histionotus, Notagogus, Legnonotus, and Macrosemiocotzus, all of which have a pectinate posterior edge on the rhombic scales (Bartram 1977a; Tintori and Renesto 1983), and unlike the cycloid scales of Enchelyolepis (Bartram, 1977a); squamation complete on the body, unlike that of Macrosemius, Legnonotus, and Macrosemiocotzus, in which a strip beneath the dorsal fin is bare of scales (Gonzalez-Rodrıguez et al. 2004)."
