ABSTRACT
Kašić-Lelo, M. & Lelo, S. Quantitative analysis of some characteristics of a local population of Cetonia aurata (Linnaeus, 1761) (Coleoptera, Cetoniidae, Cetoniinae) from Pediše village on Mt. Romanija. This paper deals with the analysis of eleven quantitative, external morphological characters and four morphometric characters of the genital apparatus (two male and two female)of thirty males and thirty females of species Cetonia aurata, Linnaeus in a local population of village Pediše on mountain Romanija. This analysis was undertaken in order to obtain base data regarding synchronic variability and variation of typical morphometric characters of the aforementioned species. Data obtained was compared between sexes.
Key words: Cetonia aurata, morphometric characteristics, variability, variation.

SUMMARY
Genus Cetonia Fabricius, 1775 is almost fully a Palaearctic genus with nineteen species in three subgenera: Cetonia Fabricius, 1775, Indocetonia Mikšić, 1965 and Eucetonia Schoch, 1894. All of the European species are members of the genus Cetonia Fabricius, 1775 with their central areal being the Mediterranean. European fauna has all of four species (Alonso-Zarazaga and Krell, 2007) (three according Baraud, 2001), one of them being C. aurata Linnaeus, 1761, the only one recorded in Bosnia and Herzegovina, and the rest are C. carthami Gory-Percheron, 1833 (Italy, Sicily, Corsica and Iberian peninsula); C. cypriaca Alexis, 1994 (Cyprus) and C. oertzeni Reitter, 1885 (Crete; Mikšić, 1965). It has been recorded that C. oertzeni Reitter, 1885 is a synonym for C. asiatica Gory-Percheron, 1833
Based on the contemporary literature Cetonia aurata (Linnaeus, 1761) in Europe, is represented by four subspecies: C. a. aurata Linnaeus, 1761: inhabiting almost all of Evrope and Balkan peninusula, Peloponese, Asia Minor and Eurosiberian regiona of Central Asia; C. a. pisana Herr, 1841: Corsica, France, Greece, Italy, Malta, Sardinia and Switzerland; C. a. pallida Drury, 1770: Turkey, Bulgaria, Ukraine and Turkistan; C. a. sicula Aliquo, 1983: Sicily (Baraud, 2001)
C. aurata (Linaeus, 1761), rose chafer, is an extremely variable species, primarily with regards to its qualitative characteristics. This is a medium sized species with body covered in fine hairs (fresh specimens) and in different vivid, metallic colours (green, copper, violet, bronze and blue). Each of its mesothoratic and metathoratic tibias have, on their ends and on their insides, two typical, apical, movable spines. Males show clear difference from females as they have a depression on their sterna (Lelo, 2000, 2003; Kašić-Lelo i Lelo, 2002, 2005).
Analysis of the rose chafer individuals from a local population of village Pediše on mountain Romanija shows a certain degree of spatial variation across a variety of quantitative characteristics. The statistical sample of 60 (30♂♂ and 30♀♀), collected on 18th July 2004, have all been characterised as f. typica, and a selection of morphological characteristics (measurements) have been statistically analysed and have shown:
- that females are generally larger than males, but these differences are not enough to determine sex of some individuals;
- comparison of basic statistical data for male and female subsamples of the given population, only just confirms generally larger size of females, while values for standard error of each of the characteristics as well as their degree of variability are almost equal between sexes;
- the only other characteristic worth noting is the length of scutellum which showed a difference in variability coefficients of only 2,05% (DG – ♂♂ 8,33; ♀♀ 6,28);
- head length variability coefficient shows that males have a “more significant” difference in their degrees of variation, but even this variation is represented with only 3,19% (DG – ♂♂ 7,69; ♀♀ 4,50).
