).
Canadian records.
Ontario: Point Pelee National Park, 23-Jun-2010 (2 exx, CBG).

). Body length 5.5-6.0 mm. Ventral surface of tarsi densely, finely pubescent (

). Male with sternite VIII deeply bilobed apically (

Comments.
This species was originally described as the only member of the new genus
Tedinus
by
Casey (1891)
.
Tedinus
was included as valid in the key to the genera of
Alleculini
by
Aalbu et al. (2002)
where it was separated from species of
Isomira
Mulsant, 1856 based on the characters listed above. In addition to the new Canadian record, three new U.S. state records were found among the DNA barcoded specimens: Florida: Destin, 25-Mar-1980 (1 ex, CNC). Oklahoma: Willis, 15-Apr-2009 (6 exx, CBG & CNC); Willis, 18-Apr-2009 (1 ex, CNC). Illinois: Pine Hills Field Station, 22-May-1967 (1 ex, CNC).
