Description synthétique Morphologie | Morphométrie

Rayons mous dorsaux (Total): 9; Rayons mous anaux: 7; Vertèbres: 31 - 32. Can be diagnosed from all members of the Rasbora trifasciata-group by having male cephalic tubercles nodular with blunt tips and the base lower than the skin surface in a narrow pit. Other combination of characters useful to further distinguished from the other members of this group in northwestern Sumatra include the following: cranial superficial neuromasts having basal plates confluent with the skin surface with no peripheral structure surrounding them; first infraorbital (lachrymal) with a posterodorsal process and a concave dorsal margin; lachrymal region peripherally pigmented with an unpigmented central area; the dorsomedial branch of the supraorbital canal extending toward the posterior margin of the frontal; an axial streak extending anteriorly and terminating between the verticals through the dorsal-fin origin and the pelvic-fin insertion; the presence of cephalic tubercles only in males; a transverse scale count anterior to the dorsal-fin origin and pelvic-fin insertion of K4/1/2K; 12 scales around caudal peduncle; unpigmented opercular flap; a basal reticulation pattern comprising of networks of well-developed parenthesis-shaped bars on the midlateral surface of the body; a maximum vertical coverage of the basal reticulation by three and a half longitudinal scale rows; and pelvic-fin rays i,8 (Ref. 85846).

Bayesian length-weight: a=0.00851 (0.00376 - 0.01926), b=3.07 (2.87 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Niveau trophique (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
Résilience (Ref. 120179):  Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
