by Lee NewmanPrior to 1986 there were many names being applied in the hobby literature to the so-called "chocolate cichlids." For the cichlid keeper, this made identification very difficult as distinctions among species were unclear, a situation that was resolved when Kullander (1986) placed the group in the newly-created genus Hypselecara. The generic name is derived from the Greek word hypselos (meaning "high"), in reference to the steep profiles of these cichlids, and acara, a colloquial word for cichlid. Kullander (1986) recognized only two species ­ Hypselecara temporalis (Gunther 1862) and H. coryphaenoides (Heckel 1840) ­ placing H. goeldii, H. crassa, and H. hellabrunni in the synonymy of the former and H. niger, H. arnoldi, and H. axelrodi in that of the latter.
