Etymology: websteri: Named for Kent Webster, discoverer of the species on the night of the Asian tsunami, who has devoted much of his life to breeding aquarium fishes, notably Australian and New Guinean rainbows, professionally in the Peninsula Hatchery, Gardena, California (Ref. 78622).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical
Africa: Akaka Camp in western Gabon (Ref. 78622).

Morphology | Morphometrics
soft rays: 11 - 13. Diagnosis: It is distinguished from all other lampeyes by the superimposed insertion of dorsal and anal fins vs. dorsal fin insertion always posterior to anal fin insertion by at least 4 rays; besides it is separated from the similarly patterned and sympatric Aplocheilichthys spilauchen by the smaller maximum size in both sexes, by the more advanced dorsal fin, by the less high peduncular depth, by the presence of red pigment markings on male sides and unpaired fins vs. silvery or gold markings, by the absence of a barred pattern on male sides vs. presence, by the absence of melanistic pigments on body vs. with many dark small spots, by the absence of extended rays in male posterior anal fin vs. presence, and by being more laterally compressed; it is separated from Procatopus, Plataplochilus and Rhexipanchax species by the more sharply pointed mouth in addition to the D/A value (Ref. 78622). It is separated from its congeners living in the same region from southern Equatorial Guinea to Cabinda by the rounded shape of the posterior margin of dorsal and anal fins in both sexes vs. cut straight along the last ray, by the vertical red bars in male vs. never such a pattern, by the more conspicious reticulated gray 'net along scale edges vs. faint or absent, and by the absence of an upper acumen or extension in caudal fin of dominant male vs. presence (Ref. 78622).
Found in a river less than 10 meters wide and less than 1 meter depth during dry season, warm water of over 80°F during the day, slightly acid water, pH just over 6, in primary forest (Ref. 78622). Non-annual reproduction with two weeks' water incubation of eggs and schooling in small groups of a few dozens of specimens of various ages and dominance; several individualos may have gone through a sex change (Ref. 78622).
