Territus

Territus is a small, poorly known genus of ground beetles in the family Carabidae. The genus was first described in 1954 by the German entomologist Karl H. J. Müller, who based the designation on a handful of specimens collected in the Mediterranean region. Taxonomically, Territus falls within the subfamily Harpalinae and is closely related to the genera Harpalus and Polyceratus. The distinguishing characteristics of Territus species include a distinctive elytral pattern with a series of dark longitudinal stripes, a relatively flattened body shape, and a pronotum that is slightly wider than long. Morphological examination of the male genitalia reveals a unique paramere structure that sets it apart from other Harpalinae genera.

Only three species have been formally described to date: Territus mediterraneus, Territus albis, and Territus ceruleus. These species are primarily found in southern Europe, ranging from Spain and Portugal through Italy and into Sicily. They prefer open, dry habitats such as scrubland, grasslands, and occasionally disturbed agricultural fields. In these ecosystems, Territus beetles act as active predators of small invertebrates, contributing to soil health and pest control.

Because little research has been conducted on this genus, its ecology, population status, and conservation needs remain largely unknown. Several unstudied populations that match the described morphological traits have been reported anecdotally, suggesting that additional species may exist. Continued taxonomic surveys and ecological studies are required to clarify the genus’s diversity, distribution, and role within Mediterranean ecosystems.
