Longitarsus doeberli, a wingless new species from Socotra Island (Coleoptera: Chrysomelidae).

Longitarsus doeberli sp. nov. (Coleoptera: Chrysomelidae: Galerucinae: Alticini), from Socotra Island is described. The new species is apparently similar to Longitarsus lederi Weise, 1889 from Caucasus with which it shares, in addition to compact body, some adaptive convergences, such as wingless condition and trend of reduction of the metatarsomere I. Based on the structure of the median lobe of aedeagus and the peculiar shape of the spermatheca, the new species shows instead the closest relationships with the species of the L. anchusae group, especially L. anchusae (Paykull, 1799) and L. anatolicus Weise, 1900.
