Summary
Baryscapus transversalis (Hymenoptera: Eulophidae) was established for first time as an egg hyperparasitoid of Thaumetopoea pityocampa (Lepidoptera: Notodontidae) in Bosnia and Herzegovina. It was reared from egg batches of pine processionary moth collected on Pinus nigra in the region of Boracko jezero. In laboratory conditions, 80 specimens of B. transversalis were reared during emerging period of 20 days between 3 and 22 November 2013. In the eggs of T. pityocampa, both males and females of B. transversalis developed, in sex ratio (♀♀:♂♂) 3:1.

Introduction
Uvod
Baryscapus transversalis Graham, 1991 (Hymenoptera: Eulophidae) was described on biological material from northern Greece (Graham 1991). Later, it was reported in other countries of the Balkan Peninsula (Noyes 2014), Iberian Peninsula (López-Sebastián et al. 2002–2003) and Asiatic part of Turkey (Mirchev et al. 2004). Bellin (1995) studied its life cycle and behaviour and established that it is an obligatory hyperparasitoid of the primary egg parasitoids on Thaumetopoea pityocampa (Denis & Schiffermüller, 1775) Baryscapus servadeii (Domenichini, 1965) and Ooencyrtus pityocampae (Mercet, 1921) (Hymenoptera: Encyrtidae). The meconium of B. transversalis was described for the first time by Schmidt et al. (1997).
This note reports B. transversalis as a hyperparasitoid of primary egg parasitoids of T. pityocampa and a new species for the fauna of Bosnia and Herzegovina.
