Genus Oxythyrea Mulsant, 1842 contains 10 species, but the larval description exists only for three of them. During several last years we collected and successfully reared nine species of Oxythyrea and used this material for the phylogenetic study including various types of data. In this talk, we are presenting the bionomy of adults and larvae of the genus. We found several interesting larval morphological characters, which can be used for the phylogeny of the genus e.g. specific types of setae and their arrangement on cranium and abdomen. We compared the biological and morphological data from adults and larvae with our molecular phylogenetic analyses based on three genes (Cox1, CytB, ITS1) under Bayesian interference method. More than 120 samples were in the dataset including all 10 currently recognized species of Oxythyrea .

Phylogenetic tree was almost congruent with already existing hypothesis postulated by SABATINELLI (1981, 1984) and separated Oxythyrea species in four different clades which can be usually supported by specific set of morphological characters (adults and larvae) as well as by bionomy of species included in the clade. Larval morphological data will be used for (re)description of these stages and in the future we will form a matrix based on morphological characters of adults and larvae for analyses combining these data with molecular ones.
