Type species. Limonius resplendens Eschscholtz, 1829 ; here designated

Description. Body narrow, elongate, subparallel at mid-length, slightly to moderately convex. Integument shining, usually with strong metallic viridescence; punctures simple and sparse, to moderately dense and umbilicate on head and prothorax; pubescence fine, decumbent, pallid. Head with frons depressed to slightly convex with shallow longitudinal impressions; supra-antennal ridge obtusely carinate, transverse. Antenna short, extending from base to apex of hind angle; segments 4–10 strongly serrate; segment 3 subcylindrical, coarsely, sparsely punctured. Pronotum with length 0.91–1.00X width; slightly convex, narrowly deplanate laterally, occasionally with shallow linear impression or polished median line on posterior declivity; hind angle in ventrolateral aspect with apex subtruncate to broadly rounded; dorsal carina strong and elevated; basal incisures deep. Prosternum with anterior lobe short, 0.32X width, moderately deflexed; intercoxal process weakly deflexed. Hypomeron with medial margin with flat, polished, sparsely punctured bead; anterior portion excavate, with strongly reflexed lateral carina; posterior margin deeply emarginate. Scutellum subpentagonal. Mesepimeron narrowly adjacent to coxal cavity. Metaventrite with anterior intercoxal process broad, truncate. Elytral striae finely impressed and punctured; intervals flat to slightly convex, finely and sparsely punctured in 2–3 irregular series. Aedeagus with median lobe attenuate, slightly deflexed apically; lateral lobe broadly sagittate apically and ventrally setose on sclerotized apex. Gonocoxites lightly sclerotized; ovipositor rods relatively short, less than 0.5X length of ventrites 1–5; bursa copulatrix narrow, slightly dilated; spermathecal receptacle saccate, with pair of lightly sclerotized plates and transverse striations; spermatheca basal, short, tubular; spermathecal reservoir basal, tubular, near base of thin accessory gland duct; a pair of saccate colleterial glands between insertion of spermathecal reservoir and accessory gland duct.

Name derivation. The genus name is a combination of " nitido -" from the Latin " nitidus " meaning "shiny," referring to the shiny integument of included species, and “ Limonius ” the original genus name of the type species.

PRINCE EDWARD ISLAND: Kings Co.: Launching, 26.viii.2001, C.G. Majka, seashore, CGMC.

Newly recorded from Prince Edward Island. In Nova Scotia collected in variously-aged coniferous, deciduous, and mixed forests. In wooded areas on poplar ( Populus sp.), willow ( Salix sp.), or on shrubs ( Brooks 1960). Larvae are predators in peat and moist, loamy soils. Adults are often found on the spring growth of conifers in and along margins of wetlands and drainages (unpublished data).
