Abstract

Abstract We describe a new subspecies of Finlayson’s squirrel (Callosciurus finlaysonii) from Hon Nghe Island in the Gulf of Thailand. This island is located off the coast of southern Vietnam. In addition, we discussed the phylogenetic relationships among C. finlaysonii subspecies distributed on the isolated islands in the Gulf of Thailand. The new subspecies (C. finlaysonii honnghensis), which is endemic to Hon Nghe Island, differs from other C. finlaysonii subspecies in pelage colouration. The mitochondrial cytochrome b sequences showed that this squirrel is closely related to C. finlaysonii albivexilli and C. finlaysonii frandseni, which are endemic to the Koh Kut and Koh Chang islands, respectively, suggesting that the three subspecies diverged approximately 30,000 years ago. After the last glacial maximum, many small islands were formed by the sea level rise in the Gulf of Thailand, which was a consequence of global warming. Following the continuous fragmentation of the Sunda Continent, each C. finlaysonii subspecies could have evolved in each geographically isolated island in this gulf. Thus, studying C. finlaysonii subspecies may be used to track the recent geological history of the Gulf of Thailand.
