Treatment

Leptusa obscura Blatchley, 1910 View in CoL , sp. propr.

Leptusa obscura Blatchley, 1910: 343 View in CoL .

Leptusa (s. str.) obscura: Bernhauer & Scheerpeltz, 1926: 555 View in CoL (as valid species).

Leptusa obscura: Pace, 1989: 82 View in CoL (as synonym of Le. canonica View in CoL ).

Type material. Lectotype of Leptusa obscura (here designated): ♀, “TYPE” (red label), “ Marion Co. Ind. [iana] W.S.B. [Blatchley] 31798 [17.iii.1898]”, “2383”, “Purdue Blatchley collection”, “ Leptusa obscura sp. nov. 4891” ( PURC).

Additional material. UNITED STATES: Pennsylvania: Clinton Co.: ♀, 26 km SEE Lock Haven, 41º03.23'N 77º09.65'W, 350m, Quercus , Tsuga , Pinus , 5.vi.1999 (V.I.Gusarov) ( SPSU).

Discussion. Pace (1989) synonymized Le. obscura with Le. canonica without having examined the type of the first species. My examination of the lectotype of Le. obscura demonstrated that it is not conspecific with Le. canonica . Leptusa obscura differs from Le. canonica in its uniform dark brown body color, its stronger pronotal punctation and its flatter pronotum. The lectotype of Le. obscura does not match the types of any other Casey species of Leptusa . This species will be redescribed when male specimens become available.

Distribution. Leptusa obscura is known from Indiana and Pennsylvania.
