Liocyrtusa nigriclavis (Hlisnikovsky, 1967) (Fig. 5, 19) Liocyrtusa nigriclavis (Hlisnikovsky, 1967): 240; Daffner 1983: 134; 1988: 285. Holotype male in HNHB (Hungarian Natural History Museum, Budapest), not seen. Type locality: Cojbalsan aimak, 820 m, 20 km SW Somon Bajanuul, Mongolia. Diagnosis. Length (pronotum + elytra) = 1.78–2.40 mm; greatest width = 1.22–1.70 mm. Pale to dark reddish brown, mostly shiny, antennal club often darker; some individuals with microsculpture on elytra. Head moderately coarsely and densely punctate. Antennal club variable in width, more robust in larger individuals. Antennomere 8 disc-like, about half width of 9. Apical antennomere clearly narrower than 9 and 10. Sides of pronotum rounded, posterior angles obtuse. Pronotum moderately finely punctate; punctures irregularly separated, more dense laterally. Elytral strial punctures coarse, separated by less than one diameter; striae cannot be separated apically from coarse interstrial punctures. Metasternum coarsely punctate; punctation dense laterally, sparse medially. Metatibia narrow, width at apex twice width at base. Male mesotibial process short, triangular. Abdominal sternite III coarsely punctate, sternites IV–VII each with transverse row of fine punctures before apex. Median lobe of aedeagus broad, apical lobes short with rounded apices (Fig. 5). Parameres (Fig. 5) broad, with membranous apices extending well beyond apices of median lobe. Internal sac as in Fig. 5. Distribution . The species is Holarctic.

Adults have been collected in the months from June to October, with most in July to September. Bionomics. In North America, the species is mostly northern or at upper elevations in boreal forest or in tundra habitats. Adults have been collected in habitats ranging from subarctic tundra to spruce-willow and pine and pine-aspen forests to mixed hardwood forest. They have been taken mostly by flight intercept traps, but also by evening car netting, and unbaited pit-traps. New material examined. We have seen 232 specimens from the following localities.
