HOLOTYPE (male): CANADA, New Brunswick, Queens Co., Bayard, at Nerepis River , 45.4426°N, 66.3280°W, 30.V.2008, R.P. Webster, coll., river margin, un- der small rocks in gravel ( LFC) 1 male . PARATYPE: labelled as the holotype ( RWC) 1 male.

Etymology. The name of this species is the Latin adjective “elongata” meaning elongate, in reference to the elongate body shape of this species.

Description. Alisalia elongata may be distinguished from the other two Alisalia species recorded from Canada by the approximately uniformly coloured body (Fig. 4), the larger size (length 2.0 mm; maximum width 0.2 mm); strongly transverse pronotum and elytra (Fig. 4), and the characteristic shape of the median lobe of aedeagus in lateral view with an elongate subapical part (Fig. 19). It has fewer transverse antennal articles than for A. testacea and A. minuta . See the key for the differences between this and the other Nearctic species.

Map 3. Collection localities in New Brunswick, Canada of Alisalia elongata

Body length 2.0 mm, narrow but distinctly broader at elytra, and with abdomen slightly tapering posteriad; approximately uniformly dark reddish-brown, but head, elytra and posterior part of abdomen appearing slightly darker than the remainder of the body, legs and bases of antennae yellowish (Fig. 4); punctation on forebody fine and dense; microsculpture inconspicuous; pubescence of head directed obliquely lateroanterad, on pronotum laterad from midline of disc, on elytra obliquely or straight posteriad, and on abdomen approximately straight posteriad (Fig. 4); antennae moderately broad as illustrated (Fig. 4); pronotum distinctly narrower than elytra, 2 times as wide as long; elytra slightly transverse; abdomen with sharply delimited horizontal basal depressions. MALE: tergite 8 truncate apically (Fig. 20); sternite 8 broadly rounded apically (Fig. 21). Median lobe of aedeagus with elongate and sinuate tubus, subapical part long and approximately straight, and medio-basal part strongly convex, crista apicalis of bulbus broad (Fig. 19), flagellum slightly projecting externally, straight in shape (Fig. 19). Paramere as illustrated (Fig. 22). FE- MALE. Unknown.
