Short description
Bestämningsnycklar | Morfologi | Morfometri
This species is distinguished from its congeners by having four dark stripes on the sides of the body, the most dorsal beginning just behind the pre-dorsal plate and finishing at the end of the adipose-fin base; the second, wider than the first one, running just above the lateral line and extending from the lateral border of the supra-occipital process to the caudal fin base; both stripes above are fragmented on its anterior portion, forming dark points that may join to form a vermiculate pattern; the dark dots and the vermiculate pattern extend over the dorsum, anterior to the dorsal-fin and head; third stripe, also wide, runs just below the lateral line and begin near the upper region of the postcleithral process and extends until the caudal fin base; fourth stripe, shorter than the three others, and absent in a few cases, begins above of the postcleithral process and ends nearly the pelvic fin; presence of a narrow light stripe on the lateral line, with about 1/3 of the width of the third dark stripe, and a dark longitudinal bar on the ventral lobe of caudal fin (Ref. 58353).
