Summary. – The Cochin Forest Cane Turtle, Vijayachelys silvatica (Family Geoemydidae), is a cryptic species in a monotypic genus endemic to the semi-evergreen and evergreen forests of the Western Ghats in southwestern India. It is the smallest turtle species in India, with carapace length (CL) in females up to 139 mm and males up to 126 mm. The species occurs at densities at 0.8 individuals per hectare and the home range varies from 3.5 to 12 ha. Vijayachelys silvatica is omnivorous, with the diet including insects, molluscs, earthworms, millipedes, and fruits. Most mating behavior occurs during the rainy season between June and November. One to two clutches are produced; the clutch size ranges from 1 to 4 eggs, and hatchlings measure 37–40 mm in CL. The major threats to this species are habitat loss and subsistence hunting. Conservation measures should focus on identification of crucial turtle habitats and creating awareness among wildlife protection staff and local people about the conservation status of the species.

Distribution. – India. Endemic to the Western Ghats of southwestern coastal India, in the states of Kerala, Karnataka, and Tamil Nadu.

Synonymy. – Geoemyda silvatica Henderson 1912, Heosemys silvatica, Vijayachelys silvatica.

Subspecies. – None recognized.

Status. – IUCN 2014 Red List: Endangered (EN B1+2c, assessed 2000); TFTSG Draft Red List: Endangered (EN, assessed 2011); CITES: Appendix II; India: Indian Wildlife (Protection) Act (1972): Schedule I.

Purple lines = boundaries delimiting major watersheds (level 3 hydrologic unit compartments – HUCs); red dots = museum and literature occurrence records of native populations based on Iverson (1992) plus more recent and authors’ data; green shading = projected native distribution based on GIS-defined HUCs constructed around verified localities and then adding HUCs that connect known point localities in the same watershed or physiographic region, and similar habitats and elevations as verified HUCs (Buhlmann et al. 2009; TTWG 2014), and adjusted based on authors’ subsequent data.
