Lugubria is a South American cichlid genus in the tribeGeophagini. It was introduced by four South American ichthyologists and their Swedish colleagueS. O. Kullander, and the name is a near-tautonym of the chosen type species. Previously, the species placed inLugubria belonged to the genusCrenicichla[1] and formed theCrenicichla lugubrisspecies complex.[2] The genus occurs throughout theAmazon Basin, in thecatchment of theOrinoco and in the coastal rivers of the threeGuyanas.[1]
Like all pike cichlids, theLugubria species have a pike-like, elongated body. They are relatively large pike cichlids and reach astandard length of 22.5 to 30 centimetres (8.9 to 11.8 in). Their scales are relatively small, which means that a row of scales on the sides of the body consists of a very large number of scales. The number of soft rays in the dorsal and anal fins is also high (13 to 18 and 9 to 13 respectively). The number of vertebrae is high (39 to 44) and there are more trunk vertebrae than caudal vertebrae, whereas the opposite is true in most other cichlid genera. The genusLugubria differs fromSaxatilia in that it lacks adark spot above the base of the pectoral fin; however, mostLugubria species show this spot in front of the base of the pectoral fin when they are older. In contrast toHemeraia andTeleocichla, inLugubria the infraorbitals 4 and 5 (bones below the eye socket) are not fused together. InLugubria the rear edge of the supracleithrum, a bone in the shoulder girdle, is not serrated, inWallaciia it is serrated.Lugubria differs fromCrenicichla (subgenusBatrachops) by the lack of a net-like color pattern on the sides of the body. All scales covering the head ofLugubria arecycloid scales.[1]
