Parasikukia maculata, a New Genus and New Species of Cyprinid Fish from Peninsular Thailand

Abstract

Parasikuhia maculata, a new genus and speeies of Cyprinidae, is described on the basis of two speeimens collected from a small river in Phetch-aburi Province, Thailand. The new fbrm is similar to the species of Sihuhia in having a deep body and adipose eyelids, but it differs from the latter in the cephalic lateral 1ine system, the shape and number of gil1 rakers, the numbers of circumpeduncular scales and vertebrae, the position of the lateral line on the caudal pedunele, and the shape of the second hypural. Parasikukia maculata is unique among the small barbs of Southeast Asia in having a small, distinct, dark, saddle-shaped spot anterior to the origin of the dorsal fin.
