The total number of species was determined as 10. Changes in comparison to the previous Turkish fauna are briefly annotated and the distributions for all species in each of the 68 biogeographical provinces are presented. After the publication of our previous fauna, 8 species belonging 2 genera have been recorded as new to Turkey. Subsequent studies reported 10 Diospilini species for the fauna, among which 7 species are distributed only in Asian Turkey and 3 species are distributed in both Asian and European Turkey. The presented checklist covers synonyms, zoogeographical region(s), hosts, host plants of host species, and parasitoid data for the species. Diospilus angorensis Beyarslan sp. nov. is described and its diagnostic characters are illustrated and compared with related Diospilini species in a key.

Introduction Asia Minor (Euxine, Mediter ranean, and Irano-Anatolian Helconinae is a moderately large subfamily containing phytogeographical provinces); only 3 species (Diospilus over 400 described species worldwide (Belokobylskij capito, D. productus, and Tapheus hiator) are known from and Lobodenko, 1997; Yu et al., 2006). All of the known Asian and European Turkey (Beyarslan et al., 2008). members of the subfamily are solitary parasitoids, although biological information is lacking for most. The 2. Materials and methods current concept of the subfamily restricts it to groups The Helconinae (Hymenoptera: Braconidae) species that are koinobiont endoparasitoids of beetle larvae, and recorded from Turkey as of the end of 2012 are listed.

Nevertheless, Helconinae is still a in comparison to the previous Turkish fauna are briefly heterogeneous assemblage and not well characterized annotated and the distributions for all species in each of by synapomorphies; like other groups based largely on the 68 biogeographical provinces are presented (Figure plesiomorphic character states, it is unlikely to be strictly 1a–1j). holophylectic (Shaw and Huddleston, 1991).
