Limnobaris dolorosa (Goeze & J. A. E. 1777)

Limnobaris dolorosa is a species of weevil native to Europe.

Its size lies between 2,8 and 4,5 mm.

Limnobaris dolorosa has characteristic ventrolateral vestiture of dense, squamiform setae, which occurs also in Limnobaris t-album and Limnobaris japonica. All three species can be distinguished from each other based on details of the male genitalia and vestiture. In addition, Limnobaris japonica is allopatric (see under this species for further details). The safest way to separate Limnobaris dolorosa from Limnobaris t-album is the short and wide penis (Figs 6, 7). Moreover, Limnobaris dolorosa has evenly dense vestiture on the entire flank, whereas Limnobaris t-album usually has less dense vestiture on the first ventrites and the metasternum.

The range of Limnobaris dolorosa extends from Western Europe (without Iberian Peninsula) to the Pacific coast (apparently without offshore islands, although Legalov (2010) reported the species from the Kuril Islands, possibly a misidentification of Limnobaris japonica). In China, the species has been found in Heilongjiang, Inner Mongolia and Jilin (Fig. 13).
