Acta entomologica serbica, 2009, 14(2): 225-235 UDC 595.76(497.6) CETONIIDAE LEACH, 1815 (INSECTA: COLEOPTERA) FROM BOSNIA AND HERZEGOVINA MIRZETA KAŠIĆ-LELO and SUVAD LELO University of Sarajevo, Faculty of Science, Zmaja od Bosne 33-35, 71000 Sarajevo, Bosnia and Herzegovina Abstract During the first decade of the 21 st century, the authors have been continuously researching the family Cetoniidae Leach, 1815 in Bosnia and Herzegovina. Certain differences have been established compared to the data of previous research, specifically the data from the 20 th century. In this work, revised and completed data are presented as well as a temporary distribution map for 17 species of the family Cetoniidae in Bosnia and Herzegovina. The most important differences to point out are the following changes we made in order to harmonize the data on Cetonids of Bosnia and Herzegovina with modern systematics and nomenclature of this family: elevation of the subfamily of Cetoniinae to the family rank Cetoniidae; previously used synonym Gnorimus octopunctatus (Fabricius, 1775) was replaced by G. variabilis (Linnaeus, 1758); and the replacement of the name Protaetia (Eupotosia) koenigi (Reitter, 1894) by the name P. (Eupotosia) mirifica (Mulsant, 1842). All the species mentioned in this paper had already been cited in the works of R. Mikšić, while in their research the authors confirmed 15 out of 17 species existing in Bosnia and Herzegovina. KEY WORDS: Coleoptera, Cetoniidae, biodiversity, Bosnia and Herzegovina Introduction The research on the Cetonidae Leach, 1815 of Bosnia and Herzegovina began at the end of the 19 th century (APFELBECK, 1912), but despite the large quantity of coleopterological material collected by Austro-Hungarian experts (V. Apfelbeck, O. Reiser, M. Hilf and A. Winneguth) in the first half of the 20 th century, a very small number of works were published about Scarabaeidae (MIKŠIĆ, 1953). In the second half of the 20 th century, thanks to intensive research by R. Mikšić, much more important results in this field were achieved, in the
