Notes. We hereby synonymize Pseudoscapiola Perepetchayenko, 1994 (type species and only known species: Myriola rudnikovi Perepetchayenko, 1994 ) with Adelius as the second author examined the type of Myriola rudnikovi Perepetchayenko. We place this species in Adelius , even though it has a single aberrant character, the 7 th antennomere distinctly protruding ventrally. Adelius rudnikovi (Perepetchayenko, 1994) is a new combination.
