Short description
Identification keys | Morphology | Morphometrics
This species can be distinguished from other congeners by the following set of characters: caudal fin with 23 or 24 rays, subtruncate and longer in males; origin of the dorsal-fin posteriorly located to anal-fin origin in males and between the base of 3rd and 5th anal-fin rays in females; 2nd proximal radial of the dorsal fin located between neural spines of the 7th and 8th vertebrae in males. The body coloration of males can also be distinguished by a combination of the following characters: three dark greenish grey bars on the anterior area of the flank; dorsal fin with transverse blue stripes and the base is lined with blue spots; presence of dots and short vermiculate marks in anal fin, irregularly arranged on the anterior part of the fin; and anterior half of caudal fin with transverse rows of blue dots, posterior half with transverse blue bars (Ref. 128003).
Inhabits temporary pools with dense aquatic vegetation, under marginal bushes. Maximum length based on type specimen, to be replaced with a better reference (Ref. 128003).
