Diagnosis
This species may be distinguished by the following combination of characters: length 4.2–4.5 mm; body dark reddish-brown, with head dark brown, and legs and at least basal three antennal articles reddish-yellow; integument glossy; pronotum with dense punctation and pubescence; elytra with dense punctation and pubescence with very fine micro-granulation (Fig. 79); head subquadrate, slightly narrower than pronotum, large eyes, each about as long as postocular region in dorsal view (Fig. 79); pronotum subquadrate, widest at apical third (Fig. 79); elytra subparallel, as wide as pronotum and at suture about as long as pronotum (Fig. 79); abdomen subparallel, about as wide as elytra (Fig. 79); Male. Apical margin of tergite VIII with broad, moderate projection in middle three-fifth, with apical margin crenulate (Fig. 81); apical margin of sternite VIII broadly parabolic (Fig. 82); median lobe of aedeagus with tubus short and straight, apical part narrowly rounded in lateral view (Fig. 80). Female. Tergite VIII rounded apically (Fig. 83); apical margin of sternite VIII with broad, shallow median emargination (Fig. 84); spermatheca short, S-shaped, capsule short, club-shaped, stem broad, sinuate, slightly twisted posteriorly (Fig. 85).
This species may be distinguished from Liogluta castoris, Liogluta pseudocastoris, Liogluta microgranulosa, and Liogluta atriventris by the following combination of characters: antennae, pronotum and elytra reddish-yellow (Fig. 79); pronotum subquadrate (Fig. 79); shape of median lobe of aedeagus different in lateral view (Fig. 80); male tergite VIII with projection crenulate along apical margin (Fig. 81), spermatheca short, S-shaped with broad stem (Fig. 85).
Natural history
Adults were collected in a conifer forest using pitfall traps, in a spruce-moss forest using carrion-baited traps, and in a highbush blueberry field. Others were collected by sifting litter and moss, sifting Alnus litter and Sphagnum moss near a pond, and treading flooded Carex and grasses. The flight period is from May to October.
