The systematics of the family Apionidae, as well as the superfamily Curculionoidea, is currently in a state of flux. The comparative analyses of COI sequences from our studies shed some light on the systematics of these weevils. To study the relationship among the organisms of the family Apionidae, we determined the COI sequences of representatives of 23 species and 15 genera, i.e., Apion, Betu...

The type specimens of species of Apionidae described by Carl Peter Thunberg are reviewed and lecto- and paralectotypes are designated for Apion craccae Thunberg, 1813, Apion limbatum Thunberg, 1813, Apion punctigerum Thunberg, 1815 and Apion astragali Thunberg, 1815. A new genus Thunbergapion (type species Apion limbatum Thunberg, 1813) is described, figured and placed in the tribe Aplemonini K...

In accordance with the International Code of Zoological Nomenclature with the express purpose of clarifying the systematic status of some species, neotypes are designated for Apion atratum Gravenhorst, 1807, Apion chloris Gravenhorst, 1807, Apion longirostre Gravenhorst, 1807 and Apion pilosellum Gravenhorst, 1807. Three new synonymies are proposed: Perapion hydrolapathi (Marsham, 1802) = Apion...

The following species of Curculionoidea are newly recorded from the Canadian province of Quebec: Coelocephalapion emaciipes (Fall, 1898); Ischnopterapion virens (Herbst, 1797); Omphalapion hookerorum (Kirby, 1808); Perapion punctinasum (J.B. Smith, 1884) (all Brentidae); Anthonomus robustulus LeConte, 1876; Pseudanthonomus helvolus (Boheman, 1843); Bagous magister LeConte, 1876; Bagous tanneri ...

The following species of Curculionoidea are recorded from Canada for the first time, in ten cases also representing new records at the generic level: Ischnopterapion (Ischnopterapion) loti (Kirby, 1808); Stenopterapion meliloti (Kirby, 1808) (both Brentidae); Atrichonotus taeniatulus (Berg, 1881); Barinus cribricollis (LeConte, 1876); Caulophilus dubius (Horn, 1873); Cionus scrophulariae (Linna...

Fothergill et al., 1997; Wachendorf et al., 2001a). Research in the northeastern USA, however, indicated that White clover (Trifolium repens L.) persists in pastures mainly by white clover may not follow this pattern in a colder stolon growth. Morphologically complex (i.e., highly branched stolons) plants of white clover generally persist longer. We hypothesized climate. White clover plants in ...
