The Alysiinae (Hym., Braconidae) parasites of the Agromyzidae (Diptera). V. The parasites of Liriomyza Mik and certain small genera of Phytomyzinae.

Abstract

1. This paper, the fifth oi aseries, deals with the Alysiinae parasites in Europe of the following genera of Phytomyzinae: Amauromyza Hendel, Campanulomyza Nowakowski, Trilobomyza Hendel, Melanophytobia Hering, Metopomyza Enderlein, Liriomyza Mik, Calycomyza Hendel and Pseudonapomyza Hendel. The parasites belong to three genera of Dacnusini (Coloneura, Dacnusa and Chorebus) and two non-Dacnusine genera, Dapsilarthra and Pseudopezomachus. - 2. Priapsis Nixon is synonymised with Coloneura Förster and a new key to Coloneura species given. Revisions are given to the key to Dacnusa in Part III (Griffiths, 1966b). Keys are also given to the parasites of certain host-groups, to facilitate the identification of bred material. - 3. Most oi the Dacnusini treated in this paper show a high degree oi host specificity, although some interesting examples oi disjunctive monophagy have come to light. A complete host / parasite list for Europe has again been prepared, including revision of previous records. - 4. Seventeen new species are described, two in Dapsilarthra, two in Coloneura, one in Dacnusa and twelve in Chorebus.
