First record of host spider amputation by the Japanese spider wasp Cyphononyx fulvognathus (Hymenoptera: Pompilidae: Pepsinae)

[摘要] The behavior of amputating the legs of spider prey by Cyphononyx fulvognathus (Pepsini, Pepsinae, Pompilidae) is reported for the first time. The prey was a female of Heteropoda, presumably H. venatoria (Araneae: Sparassidae), which is also the first prey record of Heteropoda for this wasp species. The presentobservation was found to be one of the uncommon examples of prey amputation for Pompilidae, which iscommon in species of Ageniellini (Pepsinae).
