Remarks
"Currently, there are only two species of Timarcha recognized from North America, T. cerdo Stål and T. intricata Haldeman. The characters reported to distinguish the two species (size, color, and punctation) are so variable and overlapping that I sometimes doubt that there is more than just a single species in North America. [...] very dark color and comparatively less coarse punctation is supposedly characteristic of T. intricata." --S.M. Clark, pers. comm. to =v=, 11.viii.2010
sole member of the tribe Timarchini Motschulsky 1860
