Cuculliaumbratica is known from Europe (from Spain to southern Fennoscandia), Russia, Afghanistan, Turkestan and Mongolia, in the Palearctic. In addition, introduction of this species to Canada has been reported recently. We report this species from Japan for the first time, from two locations at Hokkaidō. The earliest record is from 2015.

A new species, Dendrothrips kinape, is described and illustrated from Oryza sativa at Hokkaidô, Japan. In this genus, this species is very peculiar in its uniformly pale body color and in its host plant (first record from Monocotyledoneae). A key to Japanese species of the genus is provided.
