Abstract

The larvae, pupa, adults, and venom apparatus of Dacnusa cicerina sp. n., an endoparasitoid of Liriomyza cicerina (Rondani), found on Cicer arietinum Linnaeus in Spain, are described, illustrated, and compared with those of allied species. The mature larva of Eurytoma sp., possibly a hyperparasitoid of D. cicerina, also is described, illustrated, and compared with those of allied species. Keys to discriminate adults are provided and morphological structures of phylogenetic value are discussed. The adults of D. cicerina are similar to those of Dacnusa rodriguezi Docavo & Tormos (1997). The immature larvae are similar to those of Dacnusa areolaris (Nees) and Dacnusa dryas (Nixon), and the mature larva is very similar to that of D. dryas, from which it differs in having scale-like sensilla (“setae”) on the thorax and abdomen. The cast skin of the final instar, like those described for Dacnusa Haliday, has a pleurostoma with well differentiated mandible processes and a long stipital sclerite. The venom apparatus of this species is very similar to that of Dacnusa flavicoxa Thomson, differing from it in length of the reservoir and the number of gland filaments. The mature larva of Eurytoma Illiger described here, despite its endoparasitoid nature, has well differentiated pleural and ventral setae.
