Abstract

The larval stages of Epomis circumscriptus (Duftschmid 1812) and the first instar of Epomis dejeani Dejean, 1831, aredescribed and illustrated for the first time. Epomis adults were collected in Israel and larvae obtained ex ovo underlaboratory conditions. The larvae have an unusual mandibular morphology, with a long-hooked retinaculum in the firstinstar. This character is probably linked to the predatory habits of these carabids, which feed on body fluids and innertissues of amphibians. The genus Epomis deserves an isolated position within Chlaeniini, and a new diagnosis for thelarvae of this tribe is proposed. The life form of Epomis larvae seems intermediate between “surface runners” and“walkers”.
