Cryptophagus jakowlewi is newly recorded in Nova Scotia, Prince Edward Island, and Atlantic Canada (Fig. 2). Nearctic specimens of this species were previously known under the name of Cryptophagus confertus Casey, 1900 (synonymized by Johnson et al. 2007). It is a Holarctic species found across Canada and the northern United States, in Europe in the Alps and Scandinavia, across Siberia to the Russian Far East, and south

to Mongolia, Inner Mongolia, and Central Asia. In Europe, Lohse (1967) describes it as a boreo-alpine species. Some specimens of this species can be separated from Cryptophagus bidentatus Mäklin on the basis of external morphology only with great difficulty. The adeagi of both species are indistinguishable, however, the shape of the parameres of the two species are quite distinct ( Woodroffe and Coombs 1961).
