Abstract
The mymariform and sacciform larvae of Anaphes victus Huber (Hymenoptera: Mymaridae), an egg parasitoid of Curculionidae, are apneustic and segmented. We found a perioral cordiform structure around the buccal cavity of the mymariform larva that may have a role in the ingestion of host contents or in fights with conspecific larvae in situations of superparasitism. We observed fights between mymariform larvae, which regulate superparasitism in this strictly solitary species, in which sensorial structures of two distinct types found on the thoracic setae could have played a role. The adaptive value of these larval fights is discussed.Keywords
