Abstract: During studies on the Braconidae fauna of the Black Sea, Central Anatolian and Eastern Anatolian regions of Turkey 2 new species, Bracon (Lucobracon) kuzguni sp. n. and Bracon (Lucobracon) breviradius sp. n., were recorded and described. Important morphological diagnostic characters are fi gured and they are compared with the related species, B.(L.) triangularis Nees, 1834 and B. (L.) brachycerus Th omson, 1892 respectively.

Özet: Türkiye’nin Karadeniz, İç Anadolu ve Doğu Anadolu bölgerinde sürdürülen Braconidae faunası üzerindeki araştırmalarda; Braconinae’nin iki yeni türü Bracon (Lucobracon) kuzguni sp. n. ve Bracon (Lucobracon) breviradius sp. n. tesbit edilmiş ve tanımlanmıştır. Türlerin önemli morfolojik diagnostik karakterlerinin çizimleri yapılmış ve yakın türler olan B.(L.) triangularis Nees, 1834 ve B. (L.) brachycerus Th omson, 1892 ile karşılaştırılmışlardır.
