Definition
Ristella beddomii is a species of skink in the family Scincidae, endemic to the Western Ghats of southern India.
Overview
Described by George Albert Boulenger in 1887, R. beddomii belongs to the genus Ristella, which comprises small, ground‑dwelling skinks restricted to the Indian subcontinent. The species inhabits moist, forested hill slopes and is typically found in leaf litter and under fallen logs at elevations ranging from 500 to 1,500 m. Its distribution is recorded from the states of Kerala and Tamil Nadu, although precise locality data are limited. The International Union for Conservation of Nature (IUCN) has not evaluated the species formally; however, habitat loss due to deforestation and agricultural expansion is considered a potential threat.
Etymology/Origin
The specific epithet beddomii honors Richard Henry Beddome (1830–1911), a British army officer and naturalist who made extensive contributions to the herpetology of the Indian subcontinent, particularly the Western Ghats.
Characteristics
- Size: Adults attain a snout‑vent length (SVL) of approximately 45–55 mm; total length including the tail reaches about 90 mm.
- Morphology: The body is elongate with smooth, overlapping scales. Dorsal coloration is generally brown to olive with darker speckles, while the ventral surface is lighter, often pale yellowish.
- Scalation: The species exhibits a typical Ristella scalation pattern, including a pair of preocular scales, a single postocular, and a well‑developed supranasal. The limbs are relatively short, and each digit bears five lamellae.
- Behavior: R. beddomii is diurnal and primarily terrestrial, foraging in leaf litter for small insects and other arthropods.
- Reproduction: Reproductive biology is not well documented; available literature does not confirm whether the species is oviparous or viviparous. Accurate information is not confirmed.
