description: 2. Lypoglossa manitobae Gusarov, sp. n.
(Figs. 51–63).
Lypoglossa angularis: Hoebeke,1992: 390, ex parte.
Type material. Holotype: CANADA: Manitoba: ɗ, Riding Mtn. Nat. Park, Stathclair Trail, 4.5 km S Kinnis Creek, 12.ix.1979 (A.Smetana) (CNCI). Paratypes: CANADA: Manitoba: 2ɗɗ, 3ΨΨ, same data as the holotype (CNCI (2), CUIC (1), KSEM (1), ZMUN (1)); Ψ, Riding Mtn. Nat. Park, 1 km SE Long Lake, 16.ix.1979 (A.Smetana) (CNCI).
Diagnosis. Lypoglossa manitobae differs from L. angularis in having a smaller body size, and shorter and blunter dentiform projections at the base of the apex of the median lobe (Figs. 55–59; 25–29).
Lypoglossa manitobae can be distinguished from the Palaearctic L. lateralis by the following characters: pronotum and elytra lighter than head and abdomen; punctation of head and pronotum not asperate; and a distinct shape of the aedeagus and spermatheca (Figs. 55–63; 72–78).
L. manitobae differs from L. franclemonti in having a smaller body size; the apex of the median lobe (in parameral view) constricted basally (Figs. 55–57; 64–65); with a dentiform projection on each side of the base of the apex (Figs. 55–59; 64–67); and a smaller spermatheca (Figs. 62–63; 70).
Description. Length 3.2–3.5 mm. Head and abdomen brown; pronotum, elytra, legs, antennae and mouthparts light brown.
Head surface glossy, with weak isodiametric microsculpture, with fine punctation, distance between punctures equals 1–2 times their diameter. Eyes 1.0–1.3 times as long as temples. Antennal articles 4–6 elongate, 7–10 subquadrate.
Pronotum transverse, 1.4 times as wide as head, width 0.81–0.87 mm, length 0.60– 0.66 mm, width to length ratio 1.3–1.4; surface glossy, with weak isodiametric microsculpture; punctation finer than on head, distance between punctures equals 2 times their diameter. Elytra wider (0.89–0.91 mm) and longer (0.66–0.74 mm; measured from humeral angle) than pronotum (elytral length to pronotal length ratio 1.1), 1.3 times as wide as long, surface glossy, with poorly visible microsculpture; punctation stronger and denser than on pronotum, distance between punctures equals 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 1–3 times their diameter, terga 6–7 glossy, with sparser punctation, distance between punctures equals 2–6 times their diameter.
In males, head with weak medial impression and pronotum with broad impression along midline.
Aedeagus as in Figs. 55–61.
Spermatheca as in Figs. 62–63.
Distribution. Lypoglossa manitobae is known only from Riding Mountains National Park in Manitoba (Fig. 18) where it is sympatric with L. franclemonti.
