Mastrus genus group

(subtribe Mastrina sensu Townes (1970))

Four genera, Brachypimpla Strobl, 1902, Charitopes Förster, 1869, Lochetica Kriechbaumer, 1892, and Mastrus Förster, 1869, have been recorded from Japan. In addition, I found Isadelphus, Odontoneura Förster, 1869, and Zoophthorus Förster, 1869 from Japan. In this study, I newly record Isadelphus from Japan and review previously recorded genera. The taxonomic treatment of Odontoneura and Zoophthorus requires the additional specimens and comparison with European species. The identification of genera see Horstmann (1978).
