Among three closely related "species" in group B of Henosepilachna vigintioctomaculata complex, H. niponica and H. yasutomii are sympatric and respectively feed on thistles and blue cohosh, while H. pustulosa is allopatric with the other "species" and feeds on thistles or both thistles and blue cohosh. Under laboratory conditions, these three "species" easily interbreed with each other and produce F_1 hybrids as viable and fertile as respective homogamic offspring, showing their close genetic affinity and very incomplete post-mating reproductive isolation. This suggests the presence of a strong pre-mating isolation between two sympatric "species", H. niponica and H. yasutomii. But such a strong pre-mating isolation is ecologically difficult to assume between allopatric "species", i.e., H. pustulosa vs. H. niponica and H. yasutomii, due to the duplication of their host plants. Thus, it is likely that these "species" as a whole are still on the borderline of good biological species, nevertheless H. niponica and H. yasutomii have been sufficiently isolated with each other under sympatric natural conditions.
