Etymology: Aphyosemion: Greek, aphye, -es, sardine, anchovy + Greek, semeion = mark, signal (Ref. 45335); mengilai: This species is dedicated to François Mengila, born in Lambaréné, living in Libreville, in appreciation of his continued help as driver and guide during all collecting trips in Gabon of Wolfgang Eberl since 2002 (Ref. 95601).

背棘 (总数) : 0; 背的软条 (总数) : 13 - 14; 臀棘: 0; 臀鳍软条: 15 - 16. Diagnosis: Aphyosemion mengilai can be distinguished from all other congeners apart from A. grelli by having grey to black margins in the unpaired fins in males and females. It is distinguished from A. grelli by having more dorsal and anal fin rays in males and females, 13-14 vs. 10-12 and 15-16 vs. 13-14; by greater dorsal fin base length, 14.1-19.6% of standard length vs. 12.5-13.9%; shorter preanal length in females, 59.1-62.4% of standard length vs. 62.8-63.9%; relatively greater anal fin base length in males, 18.8-22.6% of standard length vs. 17.2-19.8%; by the more anterior insertion of dorsal fin relative to anal fin origin, ratio D/A 4-6 vs. 6-7; by having more scales on transverse series, 11-12 vs. 9-10; more scales around caudal peduncle, 15-18 vs. 12; and by the presence of light blue submarginal stripes in dorsal, anal , and caudal fin in females (Ref. 95601).
