Etymology. Named for Donald W. Barry, who collected many species for us in Maine at a site 3.5 km from the NH border, of which some have not yet been taken in New Hampshire. He is a former UNH MS graduate student and eventual Agriculture Extension Agent at the University of Maine, Orono, USA.

Diagnosis. Male tergite VIII with four sharp apical teeth, two distributed laterally and two medially, median teeth smaller ( Fig. 12c ); apical part of median lobe of aedeagus broadly triangular, elongate and sinuate ( Fig. 12b ); spermathecal capsule pitcher-shaped in lateral view, stem swollen posteriorly ( Fig. 12g ).

Description. Body length 3.21–3.79 mm, body broadly oval, moderately convex; color dark brown except paler (yellowish-brown) legs, two basal and two apical antennomeres, legs, posterior part of elytra and base of abdomen ( Fig. 12a ) (some northern specimens may be black); head distinctly narrower than pronotum ( Fig. 12a ); pronotum sub-rectangular, distinctly narrower than elytra ( Fig. 12a ); elytra at suture about as long as pronotum along midline, posterior margins broadly arcuate ( Fig. 12a ); abdomen broad, at base as wide as elytra or nearly so ( Fig. 12a ); integument strongly glossy, microsculpture of forebody with hexagonal sculpticells, pubescence sparse ( Fig. 12a ); head strongly narrowed basally behind eyes, and narrowly produced in front of eyes, eyes large and protruding, longer than genae ( Fig. 12a ); antennomeres I–III strongly elongate, IV–VI subquadrate to slightly transverse, VII–X moderately to strongly transverse ( Fig. 12a ). Male. Tergite VIII with 4 teeth, two lateral larger and two median ones smaller and in close proximity ( Fig. 12c ); sternite VIII parabolic apically ( Fig. 12d ); 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 broadly triangular and produced ventrad, its margins slightly sinuate ( Fig. 12b ).

Female. Tergite VIII truncate apically ( Fig. 12e ); sternite VIII rounded apically ( Fig. 1f ); spermatheca S-curved, capsule pitcher-shaped, median invagination shallow; stem sinuate, swollen posteriorly ( Fig. 12g ).

Distribution. Nearctic. Canada: ON. USA: ME, NH.

Collection and Habitat data. Adults were captured by flight intercept traps on the floating Sphagnum mat of a kettle bog, and by window traps on the bog margin; also, on aquatic vegetation and in ON specimens were found in Carex and moss on logs in a pond. Collected primarily from May to September in NH, ME, and ON.
