Treatment

Subgenus Ozmena Özdikmen, 2010 , stat. nov.

Ozmena Özdikmen, 2010: 265 (new name for Takagia Negrobov, 1973 , not Matsumura, 1942) (as subgenus of Sphyrotarsus Mik, 1874 View in CoL ).

Takagia Negrobov, 1973: 1520 (as subgenus of Sphyrotarsus Mik, 1874 View in CoL ) (not Matsumura, 1942). — Negrobov 1978: pl. CLXI (as genus, in error). — Type species: Sphyrotarsus stackelbergi Negrobov, 1965 View in CoL (original designation).

Diagnosis

The main diagnostic character of the subgenus is the elongate antennal postpedicel in both male and female, and the apical stylus ( Negrobov 1973). Nevertheless, some Oriental Diostracus species also have an elongate postpedicel and an apical or subapical stylus (e.g., Saigusa 1984; Yang et al. 2011). Unfortunately, there are practically no publications with pictures of female antennae in Diostracus species.

Type species

Sphyrotarsus stackelbergi Negrobov, 1965 View in CoL (by monotypy).
