E-mail: dulai@paleo.nhmus.hu Abstract - Fossil remains of eight insect orders, a false scorpion (Arachnoidea) and a Decapoda (Crustacea) species have been found in Upper Miocene lacustrine deposits of Tállya and some other localities in the close vicinity. A baetid larva is especially worth to mention, because fossil Ephemeroptera (apart from the trace fossils) were not found before in the Carpathian Basin, moreover this mayfly family hitherto was not reported from the Miocene at all. The insect-bearing laminated and sometimes tuffitic diatomaceous earth deposited in an eutrophic lake with anoxic bottom conditions. The depth of the lake was more than 10 m. Additionally, a survey is given on the fossil insects have been found earlier in the Carpathian Basin and the neighbouring territories. With 19 figures. Key words - Insecta, Arachnoidea, Crustacea, Late Miocene, Sarmatian, Hungary, Central Paratethys. INTRODUCTION Tállya as a collecting site of a few fossil insects was already reported in the 19th, and in the first part of the 20th centuries (HEER 1872, PONGRÁCZ 1923). More recently - first of all as a result of the enduring collecting activity of GYÖRGY ENCSY - a really rich and interesting fossil arthropod material came to light from the Upper Miocene lacustrine deposits of Tállya and its surroundings (Tokaj Mts, Hungary; Central Paratethys). A part of this material was already examined by JENŐ PAPP (Department of Zoology, Hungarian Natural History Museum, Budapest), and photographed by ANDRÁS KLEVE, but it was not yet published at all. Description of new taxa is not an aim of the present paper, but the authors would like to give a survey about the diversity of fossil arthropods found in this locality. Besides, in order to have a right judgement about the importance of the insect remains detailed below, it is worth to survey the insect fossils hitherto found in the Carpathian Basin and the neighbouring territories.
