Genus Campodorus Förster, 1869

Campodorus Förster, 1869: 213 . Type species: Mesoleius melanogaster Holmgren, 1857 . Designated by Perkins (1962).

Phagesorus Förster, 1869: 212 . Type species: Tryphon caligatus Gravenhorst, 1829 . Designated by Townes et al. (1965).

Cuboscopesis Heinrich, 1952: 1080 . Type species: Cuboscopesis epachthoides Heinrich, 1952 . Original designation.

Two species, Ca. circumspectus (Holmgren, 1876) and Ca. kunashiricus Kasparyan, 2003 , have been recorded from Japan, but I have found more than ten indeterminate species from Japan. The taxonomic treatment of these species except for three species requires the additional specimens and comparison with European species. In this study, I describe three new species from Japan below.

Preliminary key to Japanese species of Campodorus (modified from the key in Kasparyan (2003, 2005, 2006))

1. Tarsal claws pectinate. [Hind coxa red. Metasomal tergites without red area(s). Mesopleuron polished and punctate. Clypeus and mandible whitish yellow. Face yellow. Pterostigma uniformly brown. Hind femur darkened at apex.]

.............. Campodorus kunashiricus Kasparyan, 2003

-. Tarsal claws simple. ...................................................................... 2

2. Mesoscutum, mesopleuron, and metapleuron red to reddish brown ( Figs. 20A, D ). Length of malar space

0.1 × as long as basal width of mandible.

.............................. Campodorus rufidorsalis sp. nov. -. Mesoscutum, mesopleuron, and metapleuron black

( Figs. 18A , 19A ). Length of malar space more than 0.3

× as long as basal width of mandible.

...................................................................... 3 3. Face yellow except for a median longitudinal black stripe ( Fig. 18B ).

.......................... Campodorus albimarginalis sp. nov. -. Face entirely black ( Fig. 19B ).

...................................................................... 4

4. Hind tibia entirely reddish yellow or apical part darkened. T I 1.7–1.8 × as long as maximum width. Hind coxa and trochanter black. [Clypeus and mandible reddish yellow. Ovipositor sheath with short and moderately long setae at apex. Pterostigma pale reddish brown. Metasomal sternites and laterotergites at least mostly darkened. Fore wing vein 1cu-a interstitial to vein M&RS. Hind femur 5.5 × as long as maximum depth in lateral view.] ....................... Ca. circumspectus (Holmgren, 1876) -. Hind tibia white basally and black apically ( Fig. 19A ). T I 1.4–1.5 × as long as maximum width. Hind coxa and trochanter reddish yellow to yellow ( Fig. 19A ). ................................ Campodorus japonicus sp. nov.
