Type material. Lectotype of Acrimea acerba   (here designated): ♂, “N.[orth] Yakima, Wash.[ington state (Wickham)]”, “ acerba Csy.   ”, “TYPE USNM 39737” (red label), “CASEY bequest 1925” ( NMNH).  

Lectotype of Acrimea resecta   (here designated): ♀, “ Coeur d'Alene, IDAHO [ Wickham ]”, “ Acrimea resecta Csy.   ”, “TYPE USNM 39736” (red label), “CASEY bequest 1925” ( NMNH).  

Additional material. CANADA: British Columbia: ♂, ♀, 4 mi. W Midway , ex river debris, 6.vi.1968 (Campbell & Smetana) ( CNCI, SPSU)   .

Diagnosis. Tinotus acerbus   differs from the other Nearctic species of Tinotus   in its brown body, the weak and poorly visible microsculpture of its glossy pronotum, the strong asperate punctation of its elytra, its lack of a medial impression on the male head and pronotum, its unmodified male sternum 8, and the shape of its aedeagus ( Figs. 5–8 View FIGURES 5–9 ), in particular the straight apex of its median lobe (in lateral view ( Fig. 7 View FIGURES 5–9 )).

Additionally, Ti. acerbus   differs from Ti. morion   in its brown body color; from Ti. caviceps   in its lack of a medial impression on the male head and pronotum; from Ti. imbricatus   in its glossier pronotum, its lack of a medial impression on the male pronotum, and its unmodified male sternum 8; from Ti. parvicornis   in its glossier pronotum.

Discussion. The lectotypes of Acri. acerba   and Acri. resecta   are similar in all external characters. These lectotypes are identical in the shape of their genitalia to the male and female specimens listed above in Material and found in the same locality in British Columbia. Tinotus acerbus   is a valid species which was not included in the review of Nearctic Tinotus   by Klimaszewski & Pelletier (2002).

Distribution. Tinotus acerbus   is known from Washington, Idaho and British Columbia.
