Above: Copadichromis trewavasae (which has been known as Copadichromis "virginalis mloto Likoma") is one of three new Utaka species described by Konings (1999). (The other two are C. geertsi and C. ilesi.) Both of the C. trewavasae above are males. The one with its dorsal fin lowered was photographed underwater at Lupingu, Tanzania; that with its dorsal raised, at Makonde, Tanzania. [The type locality of this species is Membe Point, Likoma Island, Malawi. Several of the paratypes came from Chizumulu (Chisumulu) Island. Konings did not illustrate any of his type specimens, which are deposited in the Musée royal de l'Afrique Centrale in Tervuren, Belgium.]
Scroll down for an underwater photo of a female, photographed underwater at Chizumulu (Chisumulu) Island, showing the spot pattern shared by this and several other Utaka species. According to Konings' diagnosis, C. trewavasae differs from other three-spotted Copadichromis species
...by the male breeding color (black with a light blue to white 'blaze' on head and dorsum). It has fewer gill rakers (15 to 18) than C. nkatae and C. quadrimaculatus, fewer dorsal rays (in total, 27 to 28 vs. 29) than C. trimaculatus. It differs from C. mbenjii in the shape of the head, from C. verduyni and C. azureus in having a longer caudal peduncle (5.9 times vs. 7.4 and 6.5 times respectively in SL), and from C. chrysonotus by a shallower caudal peduncle (8.1 times vs. 7.2 in SL). (Konings, 1999)A valuable part of Konings' 1999 paper is the revised key to his concept of Copadichromis, which excludes striped species (but not unmarked ones). However, the publishers unfortunately introduced errors into the key; for corrections, see my note on this and other editorial gaffes in the article.
