Cychrus pangi is a species of ground beetle belonging to the genus Cychrus and the family Carabidae. This beetle is native to China, particularly found in the mountainous regions of Sichuan Province. It was first described by Thierry Deuve in 1989.

Description
Like other members of the genus
Cychrus,
Cychrus pangi exhibits distinct morphological adaptations for its specialized diet. These beetles are typically characterized by an elongated head and prothorax, and long, slender mandibles. These features allow them to effectively reach into the shells of snails and slugs, which constitute their primary prey. While precise measurements for
C. pangi specifically may vary,
Cychrus species generally range from medium to large-sized beetles, often displaying dark, sometimes metallic or iridescent, exoskeletons. Their bodies are typically somewhat flattened, aiding their movement through leaf litter and under objects.
Habitat and Distribution
Cychrus pangi is endemic to China, with its known distribution centered in the Sichuan province. These beetles generally inhabit humid, forested environments, including broadleaf and mixed forests. They are typically found in damp microhabitats such as under stones, logs, bark, and within deep leaf litter, where their gastropod prey is abundant.
Ecology and Behavior
Cychrus pangi is a highly specialized predator, primarily feeding on snails and slugs (malacophagy). Their unique head and mouthpart structure is an evolutionary adaptation for this diet, enabling them to overcome the protective shells of gastropods. These beetles are generally nocturnal, emerging from their hiding places at night to hunt for prey. Their slow, deliberate movements are characteristic of many
Cychrus species, which rely on their specialized morphology rather than speed for capturing prey.
Etymology
The specific epithet "pangi" was assigned by the describer, Thierry Deuve, and likely honors an individual named Pang, in accordance with the common practice in scientific nomenclature to commemorate researchers, collectors, or significant figures associated with the discovery or study of the species.
