Canada, New Brunswick, York Co., Canterbury near Browns Mtn. Fen, 45.8876°N, 67.6560°W, 3.VIII.2006, R.P. Webster, coll. // Hardwood forest, on slightly dried Pleurotus sp. on sugar maple (LFC). Paratype: Canada, New Brunswick, Sunbury Co., Maugerville, Portobello Creek N.W.A., 45.8992°N, 66.4245°W, 18.VII.2004, R.P. Webster, coll. // Silver maple forest, on fleshy fungi (1 ♀, RWC).

Etymology.

This species name derives from the Canadian province of New Brunswick where the types were found.

Description.

Body length 3.9-4.0 mm, narrowly oval, robust, head, pronotum, most of elytra and posterior part of abdomen brownish black, elytra with a yellowish area or spot extending obliquely from each shoulder and a short, narrow longitudinal spot along suture apically, base of abdomen, legs, two basal antennal articles and maxillary palps yellowish (Fig. 338); integument strongly glossy, densely and coarsely punctate, especially on elytra and in tergal impressions; head much narrower than pronotum, eyes large, longer than temples, antennae with articles V–X increasingly broadening toward apex; pronotum sinuate basally and rounded laterally, broadest at middle and then abruptly narrowed apicad; elytra with prominent shoulders, broader than pronotum; abdomen subparallel, three basal tergites with deep impressions, each coarsely punctate. Male. Median lobe of aedeagus with bulbus moderately large, oval, tubus long, strongly produced ventrally, its ventral margin strongly sinuate, subapical section wide and apex thin, narrow and acutely pointed ventrally in lateral view (Fig. 339); apical margin of tergite VIII broadly, shallowly emarginate between two large lateral teeth, emargination weakly crenulate (Fig. 340); sternite VIII strongly, triangularly produced apically (Fig. 341). Female. Tergite VIII slightly sinuate apically (Fig. 342); sternite VIII obtusely produced apically, apex subangulate (Fig. 343) spermatheca with capsule short, widely club shaped, stem narrow, curved (Fig. 344).

This species is externally similar to Pleurotobia bourdonae , but has a narrower, less coarsely punctate and glossier body, and yellowish body color, the apical teeth of male tergite VIII are less prominent, and the median lobe of the aedeagus is differently shaped, with the venter strongly sinuate in lateral view (Figs 332, 339).

Distribution.

Known only from NB, Canada.

Natural history.

The holotype was found in a slightly dried Pleurotus mushroom on a sugar maple in an old hardwood forest in early August, the paratype was found in a fleshy fungus in a silver maple forest in July.
