First description of the male of Gonatopus javanus (RCL Perkins) determined by mitochondrial COI sequence (Hymenoptera: Dryinidae)

摘要

Gonatopus javanus (R.C.L. Perkins) was newly recorded from Japan and India. The males collected together with females of G. javanus from Japan were identified as previously unknown opposite sex of the species because they share identical sequences of mitochondrial COI. The sequence was different from that of G. clavipes (Thunberg) by 11%. The male of G. javanus was described as new to science. Doratulina producta (Matsumura) is implied as host in Japan. The utility of molecular marker to identify the dryinid taxa showing sexual dimorphism is discussed.
