Three new melanotaeniid fishes are described from the Triton Lakes area of western Irian Jaya, Indonesia. They are closely related to one another and apparently evolved from an ancestor of the wide-ranging Melanotaenia goldiei. Melanotaenia kamaka n. sp. is described from 29 specimens, 38.5-60.5 mm SL, collected at Lake Kamakawaiar, and M. Iakamora n. sp. is described on the basis of 75 specimens, 25.5-54.9 mm SL, from nearby Lake Lakamora and Lake Aiwaso. They differ primarily in colour pattern, but also in modal number of anal fin rays and the length of the posterior rays of males (those of M. lakamora are more elongate). Melanotaenia pierucciae, the third new species, is described from 13 specimens, 28.9-58.7 mm SL, collected from a small creek near Lake Kamakawaiar. It is similar to M. kamaka and M. lakamora, but differs in colour pattern and proportions. Males are more slender and the species also has a more slender caudal peduncle, and shorter dorsal rays in the second dorsal fin. It further differs from M. kamakain having a shorter caudal peduncle and shorter anal rays.
