Type species: Dima elateroides Charpentier, 1825 : 191 . = Celox dima Schaufuss, 1862 : 202 . Diagnosis. The current generic concept of Dima includes morphologically diverse species from the Iberian Peninsula , the Balkan Peninsula , the Himalayas , East and South East Asia . Species from the Balkan Peninsula , including the type species Dima elateroides , can be recognized by the following combination of characters: body medium-sized, robust, more or less oval, 8.0– 17.1 mm long, 2.3–2.6 times as long as wide, pale brown to blackishbrown ( Figs 1–118 ), antennae weakly serrate, surpassing the pronotal posterior angles by about 1–4 antennomeres, antennomere III shortest (or subequal to antennomere II), antennomeres IV–X 1.5–2.1 times as long as wide, pronotum 1.3–1.6 times as wide as long, moderately convex dorsally, with anterior angles obtuse and posterior angles prominent, acute, more or less distinctly produced outward, tarsomeres III–IV lobate ventrally, and a typically elongate aedeagus with narrow paramera, and apical lobe bearing a more or less developed tooth ( Figs 172–221 ). Species of Dima from the Iberian Peninsula differ in having the antennae with short, bulbous, subtriangular antennomeres, and the Asian species in having much longer antennae, often reaching beyond metacoxae, and in the differently shaped male genitalia ( Schimmel 1996 , Schimmel & Platia 2008 , and personal observations).
