Description
Genus Hemiteles Gravenhorst, 1829
Hemiteles Gravenhorst, 1829: 780. Type: Hemiteles tristator Gravenhorst, 1829 (= Ichneumon bipunctator Thunberg, 1824). Designated by Westwood (1840).
Ocymorus Förster, 1869: 180. Type: Hemiteles cingulator Gravenhorst, 1829 (= Ichneumon bipunctator Thunberg, 1824). Designated by Townes (1944).
Three species, H. bipunctator (Thunberg, 1822), H. hirashimai Momoi, 1970, and H. politus (Ashmead, 1906), have been recorded from Japan. In this study, I found five additional species from Japan and four of them are undescribed. I describe them and record some distributional data of H. hirashimai below. Japanese species including new species and undetermined species can be distinguished by the following key.
Preliminary key to Japanese species of the genus Hemiteles (♀)
1. Mesoscutum largely smooth. ............................................. H. politus (Ashmead, 1906) *

-. Flagellum without a white band (e.g., Figs 41A, 42A). Fore wing with or without a clouded area (e.g., Figs 41A, D, 42A, D). Ratio of Hind TS I: II is various (usually 2.0: 0.9) (Fig. 63I). Ovipositor with or without (Fig. 66 K-M) a distinct nodus. ............................................................................................ 4

4. FL III longer than 4.5 times as long as maximum depth in lateral view. Subapical part of fore wing clouded. Pronotum laterally and mesopleuron at least partly marked with reddish brown. ...................................... H. bipunctator (Thunberg, 1822)
-. FL III shorter than 4.1 times as long as maximum depth in lateral view. Subapical part of fore wing clouded or not clouded. Pronotum and mesopleuron entirely black or at most weakly tinged with reddish brown on collar and upper part of mesopleuron (Fig. 43D). ........................................................................................... 5
5. Hind coxa, femur, and tibia entirely black except for yellowish brown area in base of tibia (Fig. 41A). Fore wing without a clouded area (Fig. 41D). ................................................................... H. kuro sp. nov.
-. At least hind coxa yellowish brown to reddish brown (Figs 42A, 43A). Fore wing with or without a clouded area (Figs 42D, 43E). ............................................................................................ 6
6. FL III 1.8 times as long as maximum depth in lateral view. Fore wing without a clouded area. ..................................................................................... H. sp.

7. Ovipositor sheath 0.75–0.8 times as long as hind tibia. T I 2.4–2.7 times as long as maximum width. Antenna with 26–30 flagellomeres. Subapical part of fore wing weakly but distinctly clouded just behind of pterostigma (Fig. 42D). ..................................................... H. maculipterus sp. nov.
-. Ovipositor sheath 0.5–0.56 times as long as hind tibia. T I 2.1–2.2 times as long as maximum width. Antenna with 22–24 flagellomeres. Subapical part of fore wing not clouded (Fig. 43E). ......................................................... H. yamatonis sp. nov.
* This species may be not Hemiteles.
