🔬 Taxonomy
🐟 Physical Description
Dorsal soft rays (total): 11; Anal soft rays: 7 - 10; Vertebrae: 39 - 41. Differs from all congeners by having the following characters: incomplete lateral line with only the anterior five to 14 scales perforated by the lateral line canal; more predorsal scales 19-25 (vs. 16 or fewer); and more transverse scales 16-17 (vs. nine to 11). Can be further separated from all its congeners, except Apareidon gransabana, by its color pattern, consisting of a dark stripe along the dorsal midline (present in most congeners) combined with four more narrow lateral stripes on the sides. The second stripe on the midlateral surface includes the perforated lateral series of scales and is the widest and darkest, which continues anteriorly through the eye onto the snout and posteriorly onto the middle caudal-fin rays. Each premaxilla possesses five teeth, a character shared only with Apareiodon gransabana and Parodon guyanensis. The premaxillary teeth usually with one large central spatulate cusp bordered on each side by one (two in one individual examined) minute lateral cusp on either side (vs. more than 9 cusps in all other species of the family) .
