🐟 Physical Description

Dorsal spines (total): 0; Dorsal soft rays (total): 15 - 16; Anal spines: 0; Anal soft rays: 16 - 18. Diagnosis: Nothobranchius insularis is distinguished from all species of the N. melanospilus group, except N. lucius, in possessing snout pointed in lateral view, jaws moderately long vs. snout blunt to weakly pointed, jaws short; caudal fin, in males, with broad dark grey to black band on the posterior margin vs. narrow; presence, in females, of dark dots over the whole flank vs. dark dots when present restricted to the posterior portion of the flank . It differs from N. lucius by having inner premaxillary teeth smaller than teeth of the outer premaxillary tooth row vs. larger; caudal fin subtruncate in males vs. rounded; in females, flank dark dots are vertically elongated and often arranged in oblique rows vs. dots rounded, arranged in horizontal rows; unpaired fins, in females, with dark grey dots when present restricted to their basal portion vs. extending over most fin; caudal, pectoral and pelvic fins shorter, caudal fin length 26.9-29.6% of standard length in males and 22.8-27.4% of standard length in females of N. insularis, vs. 31.3-34.9% of standard length in males and 30.3-32.9% of standard length in females of N. lucius; pectoral-fin length 17.1-21.8% of standard length in males and 14.2-19.3% of standard length in females, vs. 22.2-24.5% of standard length and 20.2-24.6% of standard length, respectively; pelvic-fin length 8.6-11.0% of standard length in males and 9.6-11.0% of standard length in females, vs. 11.6-13.1% of standard length and 11.5-13.0% of standard length, respectively; and three neuromasts in the posterior section of the anterior supraorbital series vs. two . : fusiform / normal; Cross section: compressed.
