Leptusa Kraatz, 1856: 60 (type species: Bolitochara pulchella Mannerheim, 1830; designated by Gusarov and Herman (2003)).

(Other references are omitted)

Diagnosis. See Pace (1989).

Discussion. Pace (1989) redescribed and illustrated most of the Nearctic species of Leptusa described by the previous authors. Unfortunately, he could not obtain the types of some Nearctic species and did not validly designate the lectotypes for some other species. Below I establish some new synonyms and designate the lectotypes for some Nearctic species omitted by Pace.
