A new species of melanotaeniid rainbowfish, Melanotaenia rubrivittata, is described from the Wapoga River system of northwestern Papua Province, Indonesia. The new taxon is described on the basis of 26 specimens, 18.0–48.7 mm SL, collected from two sites near the Tirawiwa River. It is similar to M. praecox in general appearance and morphology, but differs in possessing red body stripes, a more slender body shape in adult males, a slightly longer snout, and fewer lateral scales. Genetic analysis provides additional evidence for the separation of these taxa.
