New invasive bruchine species (Chrysomelidae: Bruchinae) in the fauna of Romania, with a review on their distribution and biology

SummaryFour allochthonous seed beetles, associated with Gleditsia triacanthos L., Albizia julibrissin Durraz. and Cercis siliquastrum L., are reported from Romania for the first time. They are Megabruchidius dorsalis (Fahraeus, 1839), M. tonkineus (Pic, 1914), Bruchidius terrenus (Sharp, 1886) and B. siliquastri Delobel, 2007 respectively. Their distribution (native, in Europe and Romania) is reviewed. Notes on biology are provided and morphological characters for the identification of these species are discussed. We also provide information about the parasitoid assemblages associated with these seed beetles, three of the parasitoid–host relationships being reported here for the first time.
