Definition
Crocidura hikmiya is a species of mammal belonging to the family Soricidae, the white‑toothed shrews.
Overview
- Taxonomy: Kingdom Animalia; Phylum Chordata; Class Mammalia; Order Eulipotyphla; Family Soricidae; Genus Crocidura; Species C. hikmiya.
- Discovery: The species was formally described in the early 2000s by researchers studying the shrew fauna of South Asia.
- Distribution: Available records indicate that C. hikmiya is endemic to Sri Lanka, where it has been reported from montane and sub‑montane forest habitats.
- Habitat: Like many Crocidura species, it inhabits leaf‑litter layers and understorey vegetation, foraging for insects and other small invertebrates.
- Conservation: The International Union for Conservation of Nature (IUCN) has evaluated the species, but the exact category may change as additional field data become available. Habitat loss due to deforestation is considered a potential threat.
Etymology / Origin
The specific epithet “hikmiya” is derived from a local term in the Sinhalese language, presumably referencing a characteristic of the animal or the region where it was first collected. The exact rationale for the name was provided in the original species description.
Characteristics
- Morphology: C. hikmiya possesses the typical shrew body plan—small size, elongated snout, and a dense pelage. The dorsal fur is generally brownish to grayish, while the ventral side is lighter. As a member of Crocidura, it lacks pigmented teeth (hence “white‑toothed”).
- Size: Adults have a head‑body length of approximately 55–70 mm, with a tail length roughly equal to or slightly shorter than the body.
- Diet: Inferred to be insectivorous, feeding on arthropods, annelids, and other small invertebrates found in forest litter.
- Behavior: Primarily nocturnal and solitary, typical of other shrew species.

Note: While the existence of Crocidura hikmiya as a distinct taxon is documented in scientific literature, detailed information on its ecology, population size, and exact conservation status remains limited and may be updated with future research.
