New data on Longitarsus rubellus species group with description of a new species from Western Balkans (Coleoptera: Chrysomelidae: Alticini)

Abstract

A new Longitarsus species is described from Western Balkans: Longitarsus carolileonardii (Bosnia and Herzegovina: Mojmilo) following the study of five specimens housed at the Hungarian Natural History Museum, Budapest. The new species belongs to the Longitarsus rubellus species group including also L. rubellus (Foudras 1860), L. gruevi Leonardi & Mohr 1974, L. refugiensis Leonardi & Mohr 1974 and L. ibericus Leonardi & Mohr 1974. Altogether, these species have similar habitus, but can be distinguished from each other mainly by the male sexual characters. A comparative table summarizes the diagnostic characters for all the species in the group. New distributional, biological and morphological data are also given.
