A REVISION OF MAGDELAINELLA JEANNEL, WITH A DESCRIPTION OF M. STUDENICAE SP N. (COLEOPTERA, LEIODIDAE, LEPTODIRINI), A NEW ENDOGEAN BEETLE FROM SERBIA

A new species of endogean leptodirine leiodids (Magdelainella studenicae sp. n.) from the valley of the Studenica River, village of Milice, near Usce in Southwest Serbia, is diagnosed and described. This new species differs clearly from all other closely related taxa. Magdelainella Jeannel belongs to a phyletic lineage which includes three more genera: Knirschiella Gueorguiev, Kosaniniella S. Curcic, Brajkovic & B. Curcic, and Derveniella Pavicevic & Perreau. Derveniella is given full generic status in the present paper; its members are known from Southeast Serbia only. Magdelainella noesskei (Apfelbeck), M. winkleri Jeannel, M. bozidarcurcici S. Curcic & Brajkovic, M. mucanjensis S. Curcic, Brajkovic, B. Curcic & Schonmann, M. milojebrajkovici S. Curcic & B. Curcic, M. zivojindjordievici S. Curcic, Brajkovic, B. Curcic & Schonmann, and M. nikolateslai S. Curcic, Brajkovic, B. Curcic & Schonmann are sharply delimited and represent valid species. The following new combinations are proposed for three species of Magdelainella: Kosaniniella hussoni (Jeannel), comb n., K. nonveilleri (Pavicevic & Perreau), comb. n., and K. orientalis (Pavicevic & Perreau), comb. n. The Magdelainella-Knirschiella-Kosaniniella-Derveniella complex is probably of Mesogeid age and origin; its species originated during the Alpine Orogeny, which affected vast areas of the Balkan Peninsula, their terra typica.
