Taxonomic classification
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta
- Order: Coleoproptera (beetles)
- Family: Carabidae (ground beetles)
- Subfamily: Pterostichinae
- Genus: Caelostomus
- Species: Caelostomus anceps
Authority
The species was originally described by Henry Walter Bates in 1886. The original combination and author citation are recorded as Caelostomus anceps (Bates, 1886).
Distribution
Available records place C. anceps in the Indomalayan region, with confirmed occurrences in Borneo and surrounding islands. Precise locality data are limited in publicly accessible databases.
Habitat and ecology
Members of the genus Caelostomus are typically ground‑dwelling predatory beetles, inhabiting leaf‑litter, forest floor debris, and under logs. Specific ecological information for C. anceps has not been published in detail; its habits are inferred from congeners.
Morphological notes
Detailed morphological descriptions for C. anceps are scarce in open‑access literature. As with other Caelostomus species, it is expected to possess a robust, elongate body, well‑developed mandibles, and striate elytra, but exact diagnostic characters are not readily available without consulting the original taxonomic monograph.
Conservation status
No assessment for Caelostomus anceps appears in the IUCN Red List or comparable conservation databases. Consequently, its conservation status is not evaluated.
