Henicospilus analis Matsumura and Uchida, 1926: 72; LCT ♀ from Ryukyus , designated by Gauld and Mitchell (1981 : 374), SEHU, missing so not examined; synonymised by Gauld and Mitchell (1981 : 374). Enicospilus molopos Chiu, 1954: 57; HT ♀ from Taiwan, TARI, examined; synonymised by Gauld and Mitchell (1981 : 374). Specimens examined. Total of 9 specimens (6♀♀3♂♂): Laos (4♀♀1♂), Taiwan (2♀♀2♂♂). No Japanese specimens available. Type series: HT ♀ of Enicospilus molopos Chiu, 1954, Rengechi, TAIWAN, 9.X.1935, S. Isshiki leg. (TARI); AT ♂ of Enicospilus molopos , Kappanzan, TAIWAN, 18.V.1930, J. Sonan leg. (TARI). Distribution. Eastern Palaearctic and Oriental regions ( Yu et al. 2016 ); this is a predominantly Oriental species. JAPAN: [ Ryukyus ] Okinawa ( Matsumura and Uchida 1926 ; Uchida 1928 ; Sonan 1940 ; Momoi 1970 ). Bionomics. Unknown. Differential diagnosis. This species resembles E. melanocarpus but can be distinguished by the presence of a glabrous area in the proximal part of the fore wing marginal cell (Fig. 42F ) (marginal cell uniformly setose in E. melanocarpus , as in Fig. 28F ) and linear central sclerite (Fig. 42F ) (central sclerite usually circular to oval in E. melanocarpus , as in Fig. 28F ) (also see Table 8 ). Remarks. Gauld and Mitchell (1981) designated the lectotype of Henicospilus analis based on the Ryukyus specimen. However, the lectotype label of H. analis was pinned to a Taiwanese specimen of E. sauteri . Although the type series (1♀2♂♂) were all collected in Ryukyus ( Matsumura and Uchida 1926 ), the author could not find any Japanese specimens of this species in the ichneumonid collection at SEHU. Therefore, the lectotype of H. analis is currently missing. However, given the similarity in label data between the missing Japanese specimens of H. analis and the type of Allocamptus orientalis , which had also been mislabelled, we strongly suspect that I. D. Gauld confused the data of H. analis and A. orientalis , and that it is unlikely that Enicospilus sauteri has been collected in Japan. Figure 42.
