Abstract - A new orophilous Ocys Stephens, 1828 from the Lombardian Prealps (Coleoptera, Carabidae, Bembidiina) - Ocys agostii n. sp. is described from Mount Caplone (Lombardian Prealps, Magasa, Brescia). The new species, micropterous and orophilous, can be easily distinguished from the other macropterous species of North Italy through the more rounded humeri, the narrower frons, the deeper interstriae with larger punctures, and the different elytral microsculpture. With respect to the other single orophilous species of Lombardy - Ocys monzinii Magrini & Vigna Taglianti, 2006 - it differs for the more convex body, with almost absent metallic lustre, the more robust antennae, the more convex interstriae, the deeper striae with larger punctures, the longer elytra and the much smaller spermatheca. Among the species of central-southern Italy and Islands, only Ocys gubellinii Magrini & Vigna Taglianti, 2006 (the geographically closest taxon) shares some characters with the new species, like the elytral microsculpture, the short antennae and the dark colour with scant metallic lustre, but it differs for many others: the more flat body, the narrower pronotum, the more angled humeri, the quite larger spermatheca. A map of the Italian species of the genus with limited distribution area is also provided for the first time.
