Murray, Stelidota geminate (Say) , S. octomaculata (Say) , S. ferruginea Reitter, Glicshrochilus quadrisignatus (Say), Lobiopa insularis (Castelnau) and Haptoncus luteolus (Erichson) ( Coleoptera , Nitidulidae ) (Williams et al., 1992).

REMARKS. Brachyserphus abruptus is the most abundant species in the Nearctic Region,

which is distributed from Yukon (British Columbia) to the south States of the USA. Moreover the species was found in the Palaearctic Region (Kolyada, 2016).

The material from the Canadian National Collection labelled by Townes as Brachyserphus parvulus (Nees, 1834) were studied and determinated by me as B. abruptus . These species differ in the ovipositor sheath characters: in B. abruptus ovipositor sheath short, in lateral view 3.2 times as long as wide ( Fig. 7 ), in dorsal view 3.9 times as long as wide ( Fig. 12 ), as opposed to B. parvulus , in which ovipositor sheath long, in lateral view 4.2–5.0 times as long as wide ( Fig. 10 ), in dorsal view 5.0–5.6 times as long as wide ( Fig. 11 ). Thus, the record of

B. parvulus in Canada is erroneous, and this species has to be excluded from the list of

Nearctic members of the genus.
