Apimela fusciceps (Casey): 1 habitus in dorsal view 2-3 median lobe of aedeagus in lateral view 4 male tergite VIII 5 male sternite VIII 8 spermatheca 6 female tergite VIII 7 female sternite VIII. Scale bars: 1 mm for habitus; 0.2 mm for remaining structures. Diagnosis. Body length 3.0-3.4 mm, subparallel, yellowish brown, head and scutellar region of elytra dark brown, strongly glossy, forebody with fine and moderately dense pubescence, punctation fine; head subquadrate, eyes large and about as long as postocular region of head, posterior angles rounded, pubescence directed straight and obliquely anteriad; antennomeres V-X slightly to strongly transverse, head broader than pronotum; pronotum slightly transverse, posterior angles angular; elytra elongate, at suture longer than pronotum, and about one fourth wider than pronotum, abdomen subparallel, with first visible four tergites deeply impressed basally, males lacking tubercles on first and fifth visible tergites. MALE. Median lobe of aedeagus with tubus strongly produced ventrally, in lateral view its venter sinuate with two more or less visible minute teeth in apical third, internal sac with complex structures as illustrated (Figs 2 [NB], 3 [holotype]); tergite VIII truncate apically (Fig. 4); sternite VIII produced apically and sharply pointed (Fig. 5). FEMALE. Spermatheca S-shaped, capsule tubular, slightly arched and with apical narrow, tubular projection coiled apically, stem sinuate and twisted (Fig. 8); tergite VIII truncate apically (Fig. 6); sternite VIII rounded apically (Fig. 7). Distribution. Formerly known from New York and North Carolina in the United States ( Casey 1894 , 1911 ). Here, reported in New Brunswick, Canada, for the first time. Collection and habitat data. In New Brunswick, this species was found along a river margin under cobblestones set in sand/gravel, often in areas with scattered grasses, sometimes away from water's edge. Adults were collected in late May and June. Comments. This species belongs to a distinct species group and has spermatheca type similar to that of A. attenuata (Casey).
