Abstract


The first myrmecophilous flea beetle genus (Myrmeconycha Konstantinov and Tishechkin, new genus) with four new species (M. erwini Konstantinov and Tishechkin, new species – Ecuador, M. gordoni Konstantinov and Tishechkin, new species – Brazil, M. pakaluki Konstantinov and Tishechkin, new species – Panama, and M. pheidole Konstantinov and Tishechkin, new species – Costa Rica) is described and illustrated. It is compared with flea beetles of the subtribe Disonychina (Coleoptera: Chrysomelidae: Galerucinae: Alticini) and may be easily differentiated based on the external and internal features, which include the waxy surface of the head and pronotum, reticulated surface of the pronotum, and four longitudinal ridges on each elytron.
