Diagnosis: Body length 1.1-1.3 mm. Body broad and strongly convex in crosssection (Fig. 7). Pronotum large in relation to elytra. Colouration usually reddish to reddish-brown.
Eyes composed of approximately 4-5 ommatidia. Pronotum approximately 1.25 times as broad as long and as broad as elytra; punctation extremely fine, barely noticeable. Elytra broad and relatively short; anterior impressions transverse and tomentose; supra-humeral carinae very fine; punctation more distinct than that of pronotum.
♂: protibia unmodified; mesotibia flattened and with dense long pubescence on inner face in apical third; metatibia weakly flattened on inner face in apical portion; aedeagus (Figs 31-33) approximately 0.3 mm long; ventral process and internal structures of distinctive shapes; parameres relatively short, thin, straight, and with very long apical seta.
Distribution and natural history: This species is rather widespread in Northwest Spain, from Galicia in the west to Navarra and La Rioja in the east (Map 3). The altitudes range from 800 to more than 2000 m.
