Etymology. Named for Gay Fortier, collector of most of the type specimens, former graduate student of the University of New Hampshire and the University of Alberta, and formerly working as a technician on mites at the Florida State Collection of Arthropods in Gainesville (now retired).

Diagnosis. Male tergite VIII with two sharp apical teeth distributed laterally, median teeth not apparent ( Fig. 13c ); apical part of median lobe of aedeagus narrowly elongate and sinuate ( Fig. 13b ); spermathecal capsule ovoid in lateral view, stem more or less evenly wide ( Fig. 13g ).

Description. Externally, except for male tergite VIII with only two teeth, this species is not distinguishable from B. barryi . Body length 3.34–3.71 mm, body broadly oval, moderately convex ( Fig. 13a ). Male. Tergite VIII with two large lateral teeth, median ones not apparent ( Fig. 13c ); sternite VIII parabolic apically ( Fig. 13d ); median lobe of aedeagus distinct, in lateral view bulbus broadly oval and slightly compressed dorso-ventrad, crista apicalis broad, of triangular shape, tubus short with apex narrowly elongate and produced ventrad, its margins slightly sinuate ( Fig. 13b). Female. Tergite VIII truncate apically ( Fig. 13e ); sternite VIII rounded apically ( Fig. 13f ); spermatheca Scurved, capsule ovoid with truncate apex, median invagination shallow; stem sinuate, evenly narrow ( Fig. 13g ).

Distribution. Nearctic. Canada: no records. USA: ME, NH.

Collection and Habitat data. Adults were captured by flight intercept traps on the Sphagnum mat of a kettle bog, from leaf litter on the bog margin, and from grass clumps in a freshwater swamp. Taken solely by a FIT in ME. Collected from May to June in NH, also taken in July at the ME site.
