| Remarks | Abstract: Channa quinquefasciata, a new species of snakehead from Torsa River, West Bengal, differs from all congeners by possessing a unique greyish to chrome-yellow body colour, with five black oblique bands horizontally along the upper half of the lateral body, dorsal-fin membrane with three rows of multiple black to brown oblong spots running horizontally along the whole fin length, and caudal-fin membrane alternating with <-shaped black spots arranged transversely. Genetically, the closest congener of C. quinquefasciata is C. stewartii from which it differs by K2-P sequence distance of 6.8-7.0%, and morphologically by the absence of numerous black spots on the flanks vs. presence, fewer dorsal-fin rays (33-35 vs. 38-40), fewer caudal-fin rays (12 vs. 13), and fewer mid-row lateral-line scales (10-13 vs. 14-16). |
