The chromosomes of two Japanese weevils, Blosyrus japonicus Sharp and Callirhopalus (= Pseudocneorhinus) obesus Roelofs, were studied. The former consists of four races: one 2n and bisexual (= Blosyrus falcatus Faust) and three parthenogenetic-4n, 5n, and 6n. In general the races are allopatric. The latter species has two races: 4n and 6n, again with distinct geographical distributions.
