Diagnosis. Lypoglossa franclemonti differs from the Palaearctic L. lateralis in having pronotum and elytra lighter than head and abdomen; punctation of head and pronotum not asperate; more elongate antennal articles; and in the shape of the aedeagus and spermatheca ( Figs. 64–70 ; 72–78).

Lypoglossa franclemonti can be distinguished from L. angularis by a less transverse pronotum, more elongate antennal articles; the apex of the median lobe (in parameral view) broadest at the base, not constricted ( Figs. 64–65 ; 25–27); no projections at the base of the apex ( Figs. 64–67 ; 25–29); a smaller sclerite of the parameres ( Figs. 69 ; 31); and the proximal loop of the spermatheca wider, almost circular ( Figs. 70 ; 32).

Lypoglossa franclemonti differs from L. manitobae in having a larger body size; apex of the median lobe (in parameral view) broadest at the base, not constricted ( Figs. 64–65 ; 55–57); no projections at the base of the apex ( Figs. 64–67 ; 55–59); a smaller sclerite of parameres ( Figs. 69 ; 61); and a larger spermatheca ( Figs. 70 ; 62–63).

Description. Length 3.8–4.6 mm. Head and abdomen brown, pronotum and elytra, legs, antennae and mouthparts reddish brown to brownish red, in some specimens elytra near scutellum and along suture darker.

Head surface glossy, with weak isodiametric microsculpture, with weak punctation, distance between punctures equal to 1–1.5 times their diameter. Eyes 0.9–1.1 times as long as temples. All antennal articles elongate or articles 9–10 subquadrate.

Pronotum transverse, 1.5 times as wide as head, width 0.90–1.09 mm, length 0.71– 0.89 mm, width to length ratio 1.2–1.3; surface glossy, with weak isodiametric microsculpture; punctation finer and denser than on head, distance between punctures equals their diameter. Elytra wider (0.96–1.21 mm) than pronotum and as long (0.70–0.87 mm; measured from humeral angle) as pronotum, 1.3 times as wide as long, surface glossy, with poorly visible microsculpture; punctation slightly asperate and denser than on pronotum, distance between punctures equal to ½–1 times their diameter.

Abdominal terga with very fine (poorly visible at 70x) microsculpture consisting of transverse waves; terga 3–5 matte due to fine and dense punctation, distance between punctures equals 1–2 times their diameter, terga 6–7 glossy, with sparser punctation, distance between punctures equals 2–4 times their diameter.

In males, head with weak medial impression and pronotum with broad impression along midline.

Aedeagus as in Figs. 64–69 .

Spermatheca as in Fig. 70 .

Distribution. Lypoglossa franclemonti is distributed in Canada and in the northeastern United States. It is known from the Northwest Territory, Alberta, Manitoba, Ontario, Quebec, Nova Scotia, New York, Vermont, New Hampshire and Maine ( Fig. 71 ). In different parts of its range L. franclemonti is sympatric with L. manitobae (in Manitoba), L. angularis obtusa (in the North­East) and L. angularis fenyesi (in Alberta). Compared to L. angularis , L. franclemonti tends to be restricted to lower altitudes and more continental conditions.

Natural History. Lypoglossa franclemonti is common in forest litter and in moss on forest floor.
