Csősz, S.: Taxonomical and distributional notes on two new and a rare Leptothorax Mayr, 1855 species for the Hungarian ant fauna (Hymenoptera, Formicidae)

scapus of L. gredleri is relatively longer (SL/HL >0.651) than that of its sibling species. All of the collected workers meet this requirements (SL/HL >0.730, n=20). Distribution - Leptothorax gredleri was a seldom reported species with underestimated frequency of occurrence in Hungary. Until now it was reported from two localities only, but it seems to be much more common than it was believed earlier. This species occurs all over our country. It has been collected from lowland Figs 3-5. 3-4 = Shape of petiole and alitrunk of Leptothorax species: 3 = L. gredleri MAYR, 1855; 4 = L. muscorum (NYLANDER, 1846); 5 = head of L. gredleri MAYR, 1855 with smooth and shinning median part of clypeus
