Summary. – The Travancore Tortoise, Indotestudo travancorica (Family Testudinidae) is a medium-sized tortoise (straight carapace length [SCL] up to 331 mm) endemic to the mountain ranges of the Western Ghats in southwestern India. The taxonomy of the genus Indotestudo has recently been revised, and I. travancorica is considered a distinct species. It is found in semi-evergreen, evergreen, moist deciduous, and bamboo forests, as well as in rubber and teak plantations, occurring mostly near streams and marshes, with a home range of 5.2–34 ha. Travancore Tortoises are omnivorous; their diet encompasses grasses to mollusks and they occasionally scavenge on dead animals. They breed from November to March in captivity, have a clutch size of 1–5 eggs, and hatchlings measure 55–60 mm SCL. The major threats to this species are hunting and habitat loss. Conservation measures should focus on protection, identification of crucial tortoise habitats, and increasing awareness among local communities.

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

Synonymy. – Testudo travancorica Boulenger 1907, Testudo (Indotestudo) travancorica, Geochelone travancorica, Geochelone (Indotestudo) travancorica, Indotestudo travancorica.

Subspecies. – None recognized.

Status. – IUCN 2011 Red List: Vulnerable (VU A1cd) (assessed 2000); CITES: Appendix II, as Testudinidae spp.; Indian Wildlife (Protection) Act (1972): Schedule IV.

Distribution:


Distribution of Indotestudo travancorica in the Western Ghats of southwestern Peninsular India; the discontinuity in the range is the Palghat Gap. Red dots = museum and literature occurrence records of native populations based on Iverson (1992) plus more recent and authors’ data; green shading = projected distribution based on GIS-defined hydrologic unit compartments (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), and adjusted based on authors’ data.
