Southeast Asian Yellowtail Rasbora

discussion

Remarks. Brittan (1954) misidentified R. tornieri from Sauk as R. dusonensis and the error is thoroughly discussed by Kottelat (1991) and Ng & Kottelat (2013 a). Visually, R. tornieri differs from its closest congener R. dusonensis by exhibiting a caudal-fin with carmine pigmentation (vs. yellow pigmentation).

description

Description. Morphometric data are given in Table 1, meristic data in Table 2. Body slender, elongate, laterally compressed, its greatest depth between pelvic-fin insertion and dorsal-fin origin. Dorsal profile of head sloping evenly from margin of upper lip to supraoccipital. Snout acutely rounded. Dorsal profile of body slightly convex from supraoccipital to dorsal-fin origin, thereafter slightly concave to caudal-fin base. Ventral profile gently convex from margin of lower lip to pelvic-fin origin, with slight concavity at isthmus; almost horizontal between pelvic- and anal-fin origins and gently concave at caudal peduncle. Mouth oblique, superior. Symphyseal knob on dentary strongly developed, fitting into corresponding indentation between premaxillae. Scales cycloid. Lateral line complete (all scales perforated; 27 – 30 + 2) its anterior portion curving ventrally. Dorsal fin pointed at tip, with slightly convex posterior margin. Dorsal-fin origin posterior to vertical through base of last pelvic-fin ray. Dorsohypural distance equal to or slightly less than distance between dorsal-fin origin and posterior orbital margin. Pectoral-fin subtriangular, with subrectangular axillary
