Abstract. Thenew eucoiline genus Banacuniculusis described toaccommodateseveral species
previously placed in Ganaspidium: Banacuniculus hunteri (Crawford), new combination; B.
merickeli (Miller), new combination; B. nigrimanus (Kieffer), new combination; B. utilis
(Beardsley), new combination; these species are all redescribed. The following new species are
described: Banacuniculus brautigani, B. beardsleyi, B. dis, and B. strykeri. As is the case with
Ganaspidium,speciesofBanacuniculusareparasitoidsofsomeofthemostpestiferousspeciesofleaf-
mining Agromyzidae (Diptera) and have been investigated for use as biological control agents of
Liriomyza trifolii (Burgess). Additional phylogenetic, host range, and distributional data, and a key
to all species are provided.
