A Revision of the Rainbowfish Genus Chilatherina (Melanotaeniidae).
Rec. West. Aust. Mus. 1981, 9(3): 279-299.
Abstract:
The six species of Chilatherina, family Melanotaeniidae, are reviewed. The genus inhabits freshwater streams of northern New Guinea between the Markham and Mamberamo Rivers and also the central highlands of Papua New Guinea. The habitat consists mainly of exposed, sunlit sections of tributary streams, although two species have lacustrine populations. A brief diagnosis, illustrations, and tables of counts are presented for each of the following species (approximate distributions indicated in parentheses): C. axelrodi (Pual River system); C. campsi (Markham River system and headwater streams of Sepik and Purari River systems); C. crassispinosa (widespread northern New Guinea); C. fasciata (widespread northern New Guinea); C. lorentzi (Tawarin River, Irian Jaya); C. sentaniensis (Lake Sentani, Irian Jaya). A generic diagnosis and key to the species are also provided.
