Diagnosis.

This species may be distinguished by the following combination of characters: body broadly subparallel (Fig. 23); pronotum, elytra, legs and basal antennal article reddish-brown, head and abdomen chestnut brown (Fig. 23); length 4.0-4.2 mm; integument of forebody with meshed microsculpture, moderately glossy; head about one-third narrower than maximum width of pronotum; pronotum more or less evenly arcuate laterally (Fig. 23); elytra at suture about as long as pronotum; basal three articles of metatarsus missing in holotype (Fig. 23). New description of male. Apical margin of tergite VIII with very broad, short, subtruncate projection with rounded lateral angles, with apical margin faintly crenulate (Fig. 25); sternite VIII broadly rounded apically (Fig. 26); median lobe of aedeagus with tubus slightly arcuate ventrally, with apex narrow and rounded (Fig. 24). Female. Tergite VIII truncate apically (Fig. 27); sternite VIII very slightly broadly emarginate apically (Fig. 28); spermatheca with tubular capsule and deep apical invagination, stem thin, long, and highly sinuate (Fig. 29).

This species is similar to Liogluta terminalis but has dark brown antennae, head and pronotum (antennae, head, and pronotum are uniformly reddish-brown or only slightly darker than remaining parts of the body in Liogluta terminalis ). Spermatheca is differently shaped in each species; Liogluta wickhami has smaller and differently shaped capsule with a deep apical invagination and has a shorter and differently looped posterior stem (Fig. 29). Liogluta wickhami is also very similar to Liogluta vasta but can be distinguished by the shape of pronotum which has evenly arcuate sides and is broadest at middle (Fig. 23), while it is trapezoidal in shape and is broadest in apical third in the latter species (Fig. 30).

Natural history.

Unknown.

Distribution.
