Specimens examined. Total of 7 specimens (5♀♀1♂ and 1 unsexed): Japan (2♀♀1♂), Sri Lanka (2♀♀ and 1 unsexed), Taiwan (1♀). Distribution. Oriental region ( Yu et al. 2016 ). Newly recorded from Japan. JAPAN: [ Ryukyus ] Okinawa. Bionomics. Unknown. Differential diagnosis. Enicospilus stenophleps can be readily distinguished from all other species of Enicospilus by the characteristic very small circular central sclerite and wide fenestra, as in Fig. 47F , although E. stenophleps is closely related to E. vestigator and E. nigribasalis .
