Description

Genus Rhembobius Förster, 1869

Rhembobius Förster, 1869: 184. Type: Phygadeuon quadrispinus Gravenhorst, 1829. Designated by Ashmead (1900a).

Ulothymus Förster, 1869: 185. Type: Ichneumon perscrutator Thunberg, 1824. Designated by Perkins (1962)

Acanthocryptus Thomson, 1873: 520. Type: Phygadeuon quadrispinus Gravenhorst, 1829.

Original designation.

Two species, Rh. perscrutator (Thunberg, 1822) and Rh. quadristriatus (Uchida, 1956), have been recorded from Japan. The latter species is recorded by only a male holotype and I could not find the type. In this study, I record the distributional data of the former below. Japanese species can be distinguished by the following key.
