Diasclera Reitter, 1913

Diasclera Reitter, 1913: 663 .

Type species: Diasclera viridescens Reitter, 1913 , by monotypy. Nacerdasclera Munster, 1921: 8 [synonymized by Švihla (1986)]. Type species: Oedemera sibirica Gebler, 1830 , by monotypy. Eumecomera Arnett, 1951: 297 , syn. nov.

Type species: Asclera obscura LeConte, 1854 , original designation.

Comments. After the examination of Eumecomera obscura ( LeConte, 1854) , the type species of genus Eumecomera Arnett, 1951 , as well as two other species occurring in the Nearctic Region, no differences between this genus and the genus Diasclera Reitter, 1913 from the Palaearctic Region were observed, so a new subjective synonym is proposed here. A diagnosis of Diasclera was given by Švihla (1986) and, following the inclusion of the Nearctic species, no essential characteristics need to be changed, except for the shape of parameres: in fact, the apical teeth can be absent. The genus Diasclera is distributed discontinuously in the Holarctic Region (see below the list of species), with a distribution that parallels that of Nacerdes , subgenus Xanthochroa Schmidt, 1846 . The Nearctic species of Diasclera were revised by Arnett (1951), and the Palaearctic ones were reviewed and discussed by Švihla (1986, 1999).
