It is also distinguished from all other species of the genus by the following combination of characters: 25-29 scales in longitudinal series (vs. 23-24), pectoral fins with vertical rows of small dark gray spots or dark gray bars in males (vs. pectoral fin without dark marks), frontal squamation F-patterned (vs. D-patterned), anterior section of supraorbital series of neuromasts continuous (vs. interrupted), dark marks on flanks mainly obliquely arranged in females (vs. mainly longitudinally or irregularly arranged), 1 + 1+ 13-17 + 1 infraorbital neuromasts(vs. 1 + 1+ 17-21 + 1), and oblique rows of dark brown dots never forming bars on flank in females (vs. forming oblique bars).</paragraph>

Caudal fin rounded. Pectoral fins rounded, their posterior margin reaching vertical between pelvic-fin base and anus in males, through pelvic-fin base in females. Pelvic fins short, slightly pointed in males, elliptical in females; tip of each pelvic fin reaching between base of 1st and 3rd anal-fin rays in males, and base of 1st anal-fin ray in females. Pelvic-fin bases in close proximity medially. Dorsal-fin origin at vertical through base of 9th or 10th anal-fin rays, between neural spines of vertebrae 18 and 20. Anal-fin origin between pleural ribs of vertebrae 12 and 14. Dorsal-fin rays 9-10; anal-fin rays 13-15; caudal-fin rays 28-31; pectoral-fin rays 15-16; pelvic-fin rays 7.</paragraph>
