Bedotia

Abstract: Bedotia masoala, a new species of Malagasy rainbowfish, is described from the Ankavanana drainage on the eastern slope of the Masoala Peninsula, northeastern Madagascar. The new species is readily distinguished from congeners by a unique blotchy, mottled, or barred lateral pigmentation pattern, and further distinguished from Bedotia marojejy, the only additional Bedotia that lacks a prominent, solid, dark midlateral stripe, by a higher vertebral count, a greater number of scales in lateral series on the flanks, and by the presence of palatine and well–developed endopterygoid tooth patches. Bedotia masoala is endemic to the Ankavanana drainage, an eastward flowing basin of the Masoala Peninsula.

Abstract: Bedotia albomarginata, a new species of Malagasy rainbowfish, is described from forested habitats in the southeastern highlands of Madagascar. The new species is distinguished from congeners by the presence of broad white margins on the second dorsal fin and anal fin in males, a markedly lanceolate caudal fin in adult males, and in life, by a bright yellow to orangish-red anal fin in both sexes. Bedotia albomarginata is known only from small streams and swamps within the upper to middle reaches of the Mananara and Rienana river drainage basins.
