Zoology

Petru Vasile ISTRATE

After an analysis of the six cyclograms, the conclusion which I got to is that in the south of Dobrogea, at the border with Bulgaria, prevail the Oriental and Mediterranean elements, namely Potosia cuprea cuprina and Eupotosia affinis, with proportional reduction of European and Central European elements, like Cetonia aurata and Eupotosia fieberi. On the whole, analysing the last cyclogram, we conclude that in Dobrogea, in general, European elements are majority, with 72%.

Conclusions

The 10 coleoptera species from Cetoniinae subfamily alerted until today in fauna of Continental Dobrogea, reveals that this geographic area of Romania houses a diverse fauna in cetoniinae. Only Liocola lugubris species, north, sibero-european element, present in Romanian fauna, and doesn’t appear in Dobrogea’s fauna. Tropinota squalida was alerted until present only in the maritime area of Dobrogea.

On the other hand, the presence of four species, of Mediterranean origin: Potosia affinis, Netocia vidua, Oxythyrea cinctella, Tropinota squalida, like Potosia cuprea cuprina subspecies of south-european and oriental origin, reveals the particularity of climate, warmer and dryer than in other parts of the country, with Mediterranean influences. The rich material collected in summer 2010 includes representatives of 9 species of coleopteras cetoniinae, with many variations of form, color and disposition of hairs drawing on body. We alert for first time in Dobrogea fauna, Cetonischema aeruginosa specie with do.aureo cuprea.
