Revision of Alloxysta from the north-western Balkan Peninsula with description of two new species (Hymenoptera: Figitidae: Charipinae)

Abstract

The aphid-associated Charipinae of Serbia, Montenegro and Slovenia have been studied. Nine species are recorded for the fi rst time from these regions: Alloxysta arcuata (Kieffer, 1902), A. brevis (Thomson, 1862), A. castanea (Hartig, 1841), A. fracticornis (Thomson, 1862), A. fuscicornis (Hartig, 1841), A. macrophadna (Hartig, 1841), A. mullensis (Cameron, 1883), A. pleuralis (Cameron, 1879), and A. salicicola Belizin, 1973. Only Alloxysta victrix (Westwood, 1833) was previously recorded from this region. The important morphological characters of these species are briefl y described and compared. Two new species, Alloxysta kovilovica Ferrer-Suay & Pujade-Villar sp. nov. and A. slovenica Ferrer-Suay & Pujade-Villar sp. nov., are described and their morphological characters are illustrated. A key for identifi cation of the Charipinae already known from the north-western Balkan Peninsula is provided.
