Enicospilus jilinensis Tang, 1990 Figure 21

Enicospilus jilinensis Tang, 1990: 72; HT ♀ from Jilin, China, FAFU, not examined.

Specimens examined.

Total of 3 specimens (2♀♀1♂): Japan (2♀♀1♂).

Distribution.

Eastern Palaearctic region ( Tang 1990; Yu et al. 2016).

Newly recorded from Japan.

JAPAN: [ Kantô-Kôshin] Tôkyô and Chiba. This species is collected only from a big city in Japan.

Bionomics.

Unknown.

Differential diagnosis.

All Japanese specimens had been misidentified as E. yonezawanus , because they lack the central sclerite of fore wing fenestra and have a strongly pigmented triangular proximal sclerite, as in Figs 21F , 54F . However, E. jilinensis can be distinguished from E. yonezawanus by many characters, such as the smooth outer mandibular surface, smaller fore wing fenestra, entirely punctate mesopleuron, and larger value of ICI.

Remarks.

Some morphological features (e.g., flattened clypeus, moderately long and slender mandible, and absence of central sclerite of fore wing fenestra) suggest a relation to E. shinkanus , which should be tested when fresh specimens are available.
