Etymology: Nanochromis: Latin, nannus = small + Greek, chromis = a fish, perhaps a perch (Ref. 45335); transvestitus: Specific name derived from the female's more intense coloration; the male is less conspicuous, a feature that is the reverse of many other cichlld species; reversed sexual dichromatism is however common and well-distributed among the chromidotilapines; females are more colorful than males in many of the genera related to Nanochromis (e.g. many Pelvicachromis species)(Ref. 52307)..
