Enicospilus concentralis Cushman, 1937: 305; HT ♀ from Taiwan, DEI, not examined.

Specimens examined.

Total of 59 specimens (51♀♀6♂♂ and 2 unsexed): Brunei (27♀♀2♂♂), Japan (22♀♀2♂♂ and 1 unsexed), Taiwan (2♀♀2♂♂ and 1 unsexed).

Distribution.

Australasian, Eastern Palaearctic, and Oriental regions ( Yu et al. 2016).

JAPAN: [ Kantô-Kôshin] Tôkyô * and Kanagawa*; [Kinki] Hyôgo *; [ Chûgoku] Hiroshima ( Konishi and Nakamura 2010; present study); [Shikoku] Tokushima*, Ehime ( Konishi and Yamamoto 2000; present study), and Kôchi *; [ Kyûshû] Fukuoka ( Konishi 1993; present study), Nagasaki ( Konishi 1993; present study), Ōita ( Konishi 1993; present study), and Kumamoto ( Konishi 1993; present study). *New records. Enicospilus concentralis is restricted to the warmer Pacific coast in Japan although has not been recorded from Ryûkyûs.

Bionomics.

Hosts unknown.

Although adult wasps are most active during summer, it is also relatively easily encountered in winter: hibernating adults are often found on the underside of leaves of evergreen plants (such as Aucubaceae shrubs).

Differential diagnosis.

Wing characters of this species (e.g., fore wing with proximal part of marginal cell widely glabrous, CI = 0.1-0.3, ICI = 0.2-0.3, and central sclerite of fore wing fenestra linear and parallel to distal margin of fenestra, as in Fig. 14F ) are unique within the genus; hence, this species can very easily be distinguished from all other species of Enicospilus .
