Holotype (female): CANADA, British Columbia, Queen Charlotte Is., 8.8 km SW Tow Hill, J.M. Campbell; 22.VIII.1983, 83–108, treading Sphagnum & Carex at edge of marsh ( CNC). Paratypes: CANADA, British Columbia, Queen Charlotte Is., 8.8 km SW Tow Hill, J.M. Campbell; 22.VIII.1983, 83–108, treading Sphagnum & Carex at edge of marsh ( CNC) 1 male, ( LFC) 1 female; British Columbia, New Denver, 13.VIII.1982, leg. R. Baranowski ( LUC) 1 male.

Etymology. The specific name charlottae is an adjective derived from the Queen Charlotte Islands, where the species was found. The Queen Charlotte Islands, in turn, were named in 1787 by Captain George Dixon after the wife of the British monarch George III, Queen Charlotte Sophia (1744–1818). Gender feminine.

Diagnosis. Body length 2.0– 2.2 mm, body moderately broad and subparallel, approximately uniformly dark brown, moderately glossy and moderately densely pubescent (Fig. 1); antennae slim, articles 5–10 slightly transverse (Fig. 1); tempora each as long as twice the maximum diameter of eye seen from above (Fig. 1); median lobe of aedeagus broad, venter of tubus arcuate laterally (Fig. 11), apical sclerites of internal sac V-shaped in dorsal view (Fig. 10); spermatheca L-shaped with capsule tubular, and without apparent apical invagination, stem moderately narrow and short (Fig. 14).

Description. Body length 2.0– 2.2 mm, width 0.4 mm, approximately uniformly dark brown with slightly paler tip of abdomen, and legs (Fig. 1); integument with weak microsculpture, sculpticells irregularly hexagonal, pubescence short, except slightly longer on head and abdomen, yellowish-brown in artificial light, moderately dense.

Head slightly elongate, rounded posteriorly, carinae not apparent, tempora as long as twice the maximal diameter of eye seen from above (Fig. 1); antennae slim with articles 5–10 slightly transverse (Fig. 1); pronotum strongly transverse, broadly rounded laterally and posteriorly, broadest in basal third, pubescence directed anteriorly on apical third of the midline and straight posteriorly and obliquely laterally elsewhere (Fig. 1); elytra moderately transverse, and subparallel, hind margin nearly straight, pubescence directed straight posteriad (Fig. 1); abdomen parallel-sided, three basal tergites deeply impressed basally (Fig. 1). Male. Median lobe of aedeagus broad and flattened, venter of tubus arcuate (Fig. 11), apical sclerites of internal sac V-shaped in dorsal view (Fig. 10); paramere as illustrated (Fig. 9); tergite 8 transverse and broadly emarginated apically, apical margin with two large and two small teeth (Fig. 12); sternite 8 elongate and rounded posteriorly, antecostal suture sinuate (Fig. 13). Female. Spermatheca Lshaped with capsule tubular and without apparent apical invagination, stem moderately narrow and approximately straight except for the twisted end (Fig. 14). Tergite and sternite 8 as illustrated (Figs 15, 16).

Bionomics. Adults were captured by treading Sphagnum and Carex at edge of marsh in August.

Geographic distribution (Map 1). Known from Canada from southern British Columbia: the Queen Charlotte Islands and New Denver.

Comments. Schistoglossa charlottae has genital structures similar to S. brunswickensis and is probably closely related to this species.
