Collection and habitat data.

Watrous (1980) reported Tetartopeus rubripennis (as Lathrobium (Tetartopeus) rubripenne ) primarily from thin litter in marshes at one locality. In northern New Brunswick, Tetartopeus rubripennis was found along river margins among gravel and cobblestones or under drift material, usually near water. Adults were collected during May and June.

Distribution in Canada and Alaska.

ON, QC, NB, NS ( Campbell and Davies 1991). In the description of Tetartopeus rubripennis , Watrous (1980) noted that the elytra are usually entirely red and rarely black with only apices reddish. Only one of the seven specimens of this species from New Brunswick had entirely reddish elytra. However, the male genitalia of the dark specimens conform to the illustration (Fig. 51) given in Watrous (1980) for Tetartopeus rubripennis . There are also specimens of the dark form from Nova Scotia and Quebec in the CNC (A. Davies, personal communication).
