Lectotype (here designated), sex unknown, labelled “Wis / Type 4780 / E. confinis Lec ”, in MCZ. Diagnosis Eustrophopsis confinis is the only Nearctic species of Eustrophinae with a combination of widely separated eyes, and transverse ridges on the outer surface of the meso- and metatibiae. In fact, it may be the only world Eustrophopsis with widely separated eyes. Also, its almost uniformly dark color separates E . confinis from E . bicolor . Description TL 4.8-6.1 mm ; GEW 2.4-3.1 mm . Body ( Fig. 6 ) ovate, subparallelsided; dorsal and ventral color uniformly dark piceous to black; antennomeres 1-4 and 11 slightly lighter in color than antennomeres 5-10; dorsal pubescence relatively long, conspicuous; eyes ( Fig. 13 ) widely separated (space 1-1.5 x length of antennomere 1), inner margin deeply emarginate; antennomeres ( Fig. 22 ) 5-10 subquadrate; antennal sensilla completely annular (as in Fig. 25 ); last maxillary palpomere unmodified, fusiform; prosternal process triangular, moderately narrowed distally, extended to slightly short of posterior margin of procoxae; prothoracic episternal suture present; elytral punctation coarse, punctures arranged in longitudinal striae ( Fig. 6 ); meso- and metatibiae with oblique ridges (as in Fig. 16 ). Distribution ( Fig. 30 ) Although specimens are seemingly rarely collected, E . confinis exhibits one of the broadest west-east ranges. Th e species is known from western British Columbia to Nova Scotia. Th e single record from Saskatchewan is the most northerly known specimen of Eustrophinae in North America. US distribution: ID, MI, ME, NE, NH, SD, WI. Natural history Label data: Polyporus anceps (ME). Chantal (1985) stated that no natural history data were known to him, but that E . confinis should be similar to other members of the group.
