Etymology. The name of this new species is derived from the name Glooscap, a mythical creator and cultural hero of the Wabanaki native peoples (the Abenaki, Mi’kmaq, Penobscot, Passamaquoddy, and Maliseet). According to the Mi’kmaq legend, when Glooscap slept, Nova Scotia was his bed and Prince Edward Island his pillow. Glooscap was the source of early environmental myths, teaching hunters that those who kill too much would destroy the world he created. According to legend, Glooscap inhabited the region where Pella glooscapi has been found. He supposedly created the neighbouring Five Islands in the Bay of Fundy by throwing stones at a giant beaver that built a dam to flood his medicine garden in Advocate. Accordingly we name this new species in honour of the rich mythology of the people of the Wabanaki Confederacy.

Diagnosis. Pella glooscapi is similar in general appearance to P. loricata but may be easily distinguished by the uniformly black body (except for tarsi and basal parts of antennae), more robust antennae (Figs. 1, 2), and differently shaped median lobe of aedeagus with broad and sinuate tubus in lateral view (Fig. 4) and the shape of spermatheca (Fig. 8). Th e closest known relative of this species would appear to be P. criddlei ( Casey 1911) , from which it may be distinguished by the black body and differently shaped male genitalia (Figs. 3–5). The latter two species have an almost identical spermatheca. This and other Pella species may readily be distinguished from members of the genus Drusilla by their lack of a distinct neck, and from the majority of Myrmoecia species by lacking abdominal trichomes and the characteristic tuberosities on the 2 nd and 3 rd visible abdominal tergites ( Klimaszewski et al. 2005).

Description. Body length 3.4–3.8 mm, subparallel, black with basal parts of antennae and tarsi reddish brown, integument glossy, forebody with distinct isodiametric microsculpture, punctation fine, pubescence yellow-brown, short and sparse, abdo-

men with central areas of tergal discs glabrous (Fig. 1); antennae robust (Figs. 1, 2), reddish-brown basally and black apically, about as long as head, pronotum, and elytra combined, basal article large and swollen, as long as 2 nd and 3 rd combined, 2 nd article about 2/3 as long as 3 rd, 3 rd article about 2/3 of the 1 st, 4 th– 7 th almost as long as wide, 7 th– 10 th slightly wider than long, 11 th slightly longer than penultimate (Figs. 1, 2); maxillary palpi 4-articled, last article needle-shaped and about 1/4 the length of the penultimate article; head elongate, broadest at eye level, strongly constricted basally, pubescence directed obliquely inwards on centre of the disc (Fig. 1); pronotum trapezoidal in shape (Fig. 1), longer than elytra, widest in apical third, strongly convex with centro-basal depression, pubescence directed posterad and forming ring around the depression, hypomeron very strong and almost as long as pronotum laterally ( Fig. 2); elytra (Fig. 1) slightly broadened posteriorly, pubescence directed straight or obliquely posterad, at base obliquely laterad; abdomen with three first visible basal tergites bearing deep longitudinal depressions, sometimes posterior edges of tergites lighter in colour, lateral edges of sternites slightly produced over sternites. Male. Tergite 8 transverse, space between antecostal suture and base of tergite narrow, antecostal suture approximately straight, apical margin truncate and with irregular small dents (Fig. 6). Sternite 8 transverse, space between antecostal suture and base of sternite narrow, antecostal suture approximately straight, apical margin broadly rounded, macrosetae small (Fig. 7); median lobe of aedeagus broadly oval in dorsal view (Fig. 3), bulbus gradually merging with tubus and tapering apically, apex broad and rounded (Fig. 3); tubus sinuate laterally and broad, apex slightly produced ventrally (Fig. 4); internal sac structures and paramere as illustrated (Figs. 3–5). Female. Tergite 8 transverse, space between antecostal suture and base of tergite narrow, antecostal suture approximately straight, apical margin truncate and smooth (Fig. 9). Sternite 8 transverse, space between antecostal suture and base of sternite narrow, antecostal suture approximately straight, apical margin broadly rounded, macrosetae small (Fig. 10). Spermatheca Lshaped, capsule with sharply produced apical projection (Fig. 8).

Bionomics. Adults were collected in June, July, August, and September in a highbush blueberry field. The area is one of mixed highbush and lowbush blueberry fields and re-growing old fields, with neighbouring mixed forests and a beaver pond.

Distribution. Known only from Nova Scotia, Canada.
