Comments. The only known state records for H. nalatus are from, or near, the type locality in southeastern Michigan. Several independent collecting efforts by the authors in 2006 and 2008 failed to produce fresh adults or nymphs, suggesting this species may no longer inhabit the Huron River.

Historical species

Capnura manitoba (Claassen)

Collection records. USA, Michigan: Montmorency Co., Hunt Creek , 44.8640, - 84.1555, 4.IV.1939, J.W. Leonard, ♂, 2 nymphs ( INHS) GoogleMaps .

Comments. This is the only member of this genus that is distributed east of the Great Plains region, known from Manitoba east to Atlantic Canada ( Nelson & Baumann 1987, DeWalt et al. 2012a). This historical record still represents one of only two known localities for this species in Michigan. A second locality is listed in Nelson & Baumann (1987) from Ogemaw County. Both counties are located in the northern tier of the Lower Peninsula.
