The Norwegian species of Aphelinus Dalman

The genus Aphelinus Dalman, 1820 comprises 91 described species worldwide; 33 of these are known from Europe ( Hopper et al., 2012; Noyes, 2013). Only 3 species have hitherto been recorded from Norway, i.e., Aphelinus abdominalis (Dalman, 1820) , A. chaonia Walker, 1839 , and A. varipes (Förster, 1841) ( Compton, 1981) , while 2 species, A. asychis Walker, 1839 and A. mali (Haldeman, 1851) , are reported for the first time from Norway; 3 species are described here as new to science. Diagnosis, hosts, and taxonomic status of all these species can be found in Nikolskaja and Yasnosh (1966) and Noyes (2013).
