Description
Summary:Beronaphaenops gen. n. paphlagonicus sp. n., a new remarkable, eyeless species of Trechini is described from Asian Turkey (type locality: cave Eşek Çukuru Mağarası 2, Milli Park Küre Dağlari, Pinarbasi District, Kastamonu Province). This specialized, troglobite species is characterized by a very peculiar combination of features, including several autapotypic features: mentum tooth large, long and porrect, at distal position reaching or slightly exceeding the level of epilobes, rather slanting ventrally, deeply bifid at the tip; short and fragile paraglossae, hardly surpassing the anterior margin of ligula; absence of posterolateral setae of the pronotum; absence of posterior discal pore in elytral stria 3; apical stylomere shortened, with basal part unusually broadened. The systematic position of the genus amongst the trechine beetles from the peri-Pontic area is discussed. A key to the Anatolian genera of the tribe is prepared.
