A new aleocharine rove beetle, Pella glooscapi Klimaszewski & Majka, sp. n., from Nova Scotia, Canada, is described and illustrated. Data on bionomics and distribution are provided. A short diagnosis, description, colour body image, and black and white genital images are also provided. It appears to be closely related to P. criddlei (Casey). Pella loricata (Casey), Zyras obliquus (Casey), and Dalotia coriaria (Kraatz) are newly recorded from Nova Scotia, and for Atlantic Canada as a whole.
