Although specimens of Divandu albimarginatus were collected as early as 1959 and again in 1986, is was not until Victor Mamonekene collected this cichlid in 1990 and 1992 that it was finally given its due.

In 1993, the late Dr. Guy Teugels and Mr. Victor Mamonekene noted a new cicihld collected in the Mayombe Forest in Congo-Brazzaville. From 1991-1992, they had been working in the Mayombe region to study the fishes of the biosphere reserve of Dimonika, as part of a larger project encompassing the flora and fauna of this protected area. Dr. Teugels explained to this writer that although their new discovery bore a resemblance to Chromidotilapia and to Limbochromis, it could not be assigned to any published genus.

Doctors Lamboj and Snoeks named this central African cichlid, Divandu, the local name for Chromidotilapia-type cichlids, albimarginatus, from the Latin "albus" (white) and "marginatus" (edged or bordered), in reference to this species' "white margin on the lower edge of the caudal fin in preserved specimens" (Lamboj & Snoeks, 2000).

D. albimarginatus can be distinguished from the other species of the chromidotilapiine lineage, in part, by a series of combined morphological characterists including, but not limited to, low levels of sexual dimorphism and dichromatism (coloration), a longer first pelvic fin ray in both sexes, 2 1/2-3 scales between the highest point of the upper lateral line and the dorsal fin base, and a reduced number of scale rows around the caudal peduncle (12 vs. 14-16 in some other species). For coloration, please refer to the photos above. â€"Randall Kohn (with special thanks to the late Dr. Guy Teugels and hobbyist Florent de Gasperis who collected D. albimarginatus himself!)
