Descriptions of adults, immature stages and venom apparatus of two new species of Dacnusini: Chorebus pseudoasphodeli sp. n., parasitic on Phytomyza chaerophili Kaltenbach and C. pseudoasramenes sp. n., parasitic on Cerodontha phragmitophila Hering (Hymenoptera: Braconidae: Alysiinae; Diptera: Agromyzidae)

The imagines, cast skin of the final larval instar, and venom apparatus of Chorebus pseudoasphodeli sp. n., an endoparasitoid of Phytomyza chaerophylli Kaltenbach, 1856 on Daucus carota L., and Chorebus pseudoasramenes sp. n., an endoparasitoid of Cerodontha phragmitophila Hering, 1935 on Arundo donax L., two new species of Dacnusini from Spain, are described, illustrated, and compared with those of allied species. The immature larvae, mature larva, and pupa of C. pseudoasphodeli sp. n. are also described, illustrated, and compared. Morphological structures of phylogenetic value are discussed, and keys for the discrimination of the imagines are provided.

Keywords: Hymenoptera, Braconidae, new species, hosts, immature stages, venom apparatus, Spain
