(1965 : 329), SEHU, examined. Specimens examined. Total of 51 specimens (42♀♀9♂♂): India (2♀♀), Japan (40♀♀8♂♂), Philippines (1♂). Type series: LCT ♀ of Henicospilus maruyamanus Uchida, 1928, Maruyama, Sapporo, Hokkaido , JAPAN, 11.VIII.1926, Uchida leg. (SEHU). Distribution. Eastern Palaearctic region ( Yu et al. 2016 ); new to the Oriental region, this is a predominantly Eastern Palaearctic species. Newly recorded from India and Philippines. JAPAN: [ Hokkaido ] ( Uchida 1928 ; present study); [ Tohoku ] Aomori ( Ichita 1994 ; Kudo et al. 1999 ); [Hokuriku] Niigata*; [ Kanto-Koshin ] Tochigi*, Nagano*, and Kanagawa ( Watanabe et al. 2016 ); [ Chugoku ] Hiroshima*; [Shikoku] Ehime* and Kochi *; [ Kyushu ] Fukuoka* and Saga*; [ Ryukyus ] Okinawa*. *New records. Bionomics. Unknown. Differential diagnosis. This species resembles E. biharensis , E. pudibundae , and E. transversus , but can be distinguished from them by the following combination of character states: uniformly pectinate hind tarsal claw; weakly to moderately sinuate fore wing vein 1m-cu&M (Fig. 26F ); and punctostriate meso- and metapleuron (Fig. 26E ) (cf. Table 7 ). Figure 26. Enicospilus maruyamanus (Uchida, 1928) ♀ from Japan A habitus B head, frontal view C head, dorsal view D head, lateral view E mesosoma, lateral view F central part of fore wing. Table 7. Comparison of diagnostic characters of Enicospilus species in Japan and its adjacent areas that share the narrow and linear fore wing proximal sclerite without central sclerite: E. biharensis , E. maruyamanus , E. pudibundae , and E. transversus .
