Etymology: Nothobranchius: Greek, nothos = false + Greek, brangchia = gill (Ref. 45335); prognathus: Name from the Latin prognathus, referring to the distinctive lower jaw of the new species that is anteriorly projected slightly beyond the upper jaw; an adjective (Ref. 119668).

Diagnosis: Nothobranchius prognathus differs from all other species of the Nothobranchius melanospilus complex in possessing lower jaw anteriorly projecting beyond upper jaw vs. not projecting; pelvic fins medially united in males vs. bases just in contact, but not united; and presence of three longitudinal series of scales on frontal region vs. two (Ref. 119668). It is also distinguished from all other species of the N. melanospilus complex by the combination of the following morphological character states: dorsal-fin origin anterior to anal-fin origin in both sexes vs. posterior in N. melanospilus; 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 dark spots on anterior part of flank vs. dots absent on anterior part in N. melanospilus; body depth 32.7-35.5% of standard length in males, 32.1-33.4% of standard length in females vs. 27.5-32.2% and 27.1-30.9% of standard length in N. melanospilus and 28.7-30.9% and 25.8% of standard length in N. kwalensis; dorsal-fin base length 27.9-29.9% of standard length in males, 23.5-25.0% of standard length in females vs. 24.6-27.9% and 19.9-23.4% of standard length in N. melanospilus and 24.1-27.3% and 2.9% of standard length in N. kwalensis; head depth 90.4-99.2% of head length in males, 85-6-90.3% of head length in females vs. 78.0-87.8% and 74.6-80.7% of head length in N. melanospilus and 79.0-82.9% and 69.5% of head length in N. kwalensis; eye diameter 20.9-25.9% of head length in males, 21.1-24.4% of head length in females vs. 26.8-28.4% and 27.1% in N. kwalensis (Ref. 119668).
