背棘 (總數) : 0; 背的軟條 (總數) : 14 - 16; 臀棘: 0; 臀鰭軟條: 16 - 18. Diagnosis: Nothobranchius kwalensis is distinguished from all other congeners of the N. melanospilus complex by the combination of the following morphological character states: lower jaw not anteriorly projecting beyond upper jaw vs. anteriorly projecting in N. prognathus; dorsal-fin origin anterior to anal fin origin in females vs. posterior in both sexes in N. melanospilus; pelvic fins medially in contact vs. bases medially united in males of N. prognathus; presence of two longitudinal series of scales on frontal region vs. three in N. prognathus; anterior supraorbital series of neuromasts divided in two sections vs. arranged in a single continuous row in N. melanospilus; mandibular neuromasts 14-16 vs. 17-21 in N. melanospilus; in females, few rounded black dots on anterior portion of flank vs. dots absent on anterior portion of flank in N. melanospilus; body depth 28.7-30.9% of standard length in males, 25.8% of standard length in female, vs. 32.7-35.5% and 32.1-33.4% of standard length respectively in N. prognathus; dorsal-fin base length 24.1-27.3% of standard length in males vs. 27.9-29.9% of standard length in N. prognathus; head depth 79.0-82.9% of head length in males, 69.5% in female, vs. 90.4-99.2% and 85.6-90.3% of head length respectively in N. prognathus; eye diameter 26.8-28.4% of head length in males, 27.1% in female vs. 20.9-25.9% and 21.1-24.4% respectively in N. prognathus (Ref. 119668).
