See Shinohara (1995) for more references.

Material examined. Forty-one specimens, including six specimens from Korea (Shinohara 1995) .

Distribution. Europe, Kazakhstan, South Korea, Japan (Hokkaido).

Host plant. Salicaceae : Populus tremula ( Stritt 1935) , Populus tremula var. davidiana ( Shinohara & Hara 1999, 2005) and? Populus nigra ( Midtgaard 1987) .

Remarks. This species is widely spread in Eurasia but very rare in the Far East, known only from small series of specimens from Korea (Shinohara 1995) and Hokkaido, Japan ( Shinohara & Hara 1997a, 1999, 2005). We have seen no specimens from the Russian Far East. This species is the sole representative of P. histrio subgroup of P. histrio group.

In our molecular analysis using COI ( Fig. 142 ), the specimens of P. histrio formed a clade but it was rather distantly located from the clades represented by five other species of the P. histrio group ( P. brevicornis , P. gyllenhali , P. tricolor , P. betulae and P. festivus ). In the NaK analysis, P. histrio was not treated. The COI result was in line with the cladistic analysis based on morphology (Shinohara 1995), where P. histrio was situated remotely from the clade including the three species given above. The monophyly of the P. histrio group as a whole was not supported by our molecular study as noted in the remarks for the species group.
