Phylogenetic position and osteology of Pethia setnai (Chhapgar & Sane, 1992), an endemic barb (Teleostei: Cyprinidae) of the Western Ghats, India, with notes on its distribution and threats

Abstract

Pethia setnai is an endemic and threatened freshwater fish of the Western Ghats of India. It has a restricted distribution in the west flowing rivers in the states of Maharashtra, Goa and Karnataka. We clarify the phylogenetic position of Pethia setnai, provide osteological details of topotypic material, and morphometric data of specimens from Maharashtra, Goa and Karnataka. We also provide details on micro-level distribution, habitat and threats to the species in its native range.
