Empria

Prous, Marko, Heidemaa, Mikk, Akihiko, Shinohara & Soon, Villu, 2011, Review of the sawfly genus Empria (Hymenoptera, Tenthredinidae) in Japan, ZooKeys 150, pp. 347-380 : 361-362

Empria sp. 1

Taxonomic affinities.

Belongs to Empria longicornis group. Externally it is most similar to Empria japonica , but penis valve is clearly distinct from all other known species of the longicornis-group (Fig. 36), being most similar to Empria alpina Benson, 1938 (e.g. http://www.morphbank.net/?id=577439). Can be distinguished from Empria alpina by its colouration: in Empria sp1 tegulae, posterior margin of pronotum, and basal 1/3 of metatibia are pale, while in Empria alpina these are mostly black. Distinctness of this taxon is also supported by nuclear ITS sequence data (Fig. 38).

Host plants.

Unknown.

Distribution.

Japan (Hokkaido).

Notes.

Because taxonomy of the longicornis-group is quite difficult ( Prous et al. 2011b) and the corresponding female remains to be found yet, additional material is needed to describe and name this presumably new species.
