Boreostiba Lohse in Lohse et al., 1990

Boreostiba Lohse in Lohse et al., 1990: 190 ( type species: Homalota sibirica Mäklin, 1880 , by original designation).

Diagnosis. See Lohse et al. (1990).

Discussion. Lohse et al. (1990) included in the genus Boreostiba five species. Two of them, Boreostiba sibirica ( Mäklin, 1880) (the type species) and Boreostiba frigida (J. Sahlberg, 1880) (see Discussion for that species), have a long, completely fused and tubelike bridge of the median lobe and enlarged condilites of the parameres. Two other species included in Boreostiba by Lohse ( Lohse et al. 1990), Boreostiba hudsonica Lohse, 1990 (a junior synonym of Atheta parvipennis Bernhauer, 1907 ; see above) and Boreostiba campbelliana Lohse, 1990 lack these features of the aedeagus and are very similar to a species ( Dimetrota smetanai Lohse, 1990 ) placed by Lohse in a different genus. The males of Boreostiba lagunae Lohse, 1990 are unknown but this species is more similar to Boreostiba campbelliana than to Boreostiba sibirica . Until a generic revision of Athetini is completed, Boreostiba hudsonica , Boreostiba campbelliana and Boreostiba lagunae are placed in Atheta .
