Pelvicachromis sp. Blue Fin has finally been described:
Lamboj, A. (2009). A new dwarf cichlid genus and species (Teleostei, Cichlidae) from Guinea, West Africa. Zootaxa. 2173, 41-48.
Abstract
Enigmatochromis lucanusi, a new cichlid genus and species, is described from Guinea (West Africa). It is a member of the chromidotilapiine cichlid clade, and differs from other genera within the group in a combination of morphological characters and coloration patterns; e.g., twelve circumpeduncular scales; three tubular infraorbital bones in addition to the lachrymal bone; upper lateral-line separated from the dorsal-fin base; first ray of pelvic fin in adult females of equal length or longer than second ray; sexual dimorphism well developed; small juveniles with 3–4 rows of irregular dark dots on body; and breeding coloration of females.
Introduction (part)
In 2004, a small cichlid species from Guinea was introduced into the aquarium hobby by several commercial importers in Canada, the U.S.A. and Europe. This new cichlid clearly was a member of the chromidotilapiine cichlid assemblage sensu Greenwood (1987) as it possessed the characteristic combination of features of this group: (1) a typical, visor-like and well circumscribed projection (“hanging padâ€) of the pharyngeal tissues situated anterior to the upper pharyngeal bones of each side; (2) no microbranchiospines; (3) outer-row jaw teeth unicuspid; (4) some anterolaterally positioned teeth in the outer tooth row of the lower jaw, curved directly posteriorly and not buccally as they are in all other tooth rows; (5) tuberculate gill rakers on the first ceratobranchial. Females possessed coloration patterns unknown from any other species within this assemblage, e.g., a bright blue dorsal-fin in females. The species was initially called Pelvicachromis sp. “blue finâ€, and was thought to be closely related to P. roloffi. Further morphological and behavioral observations however revealed differences from the genus Pelvicachromis.
