Casey, 1894: 331. As
Atheta (Liogluta)
:
Bernhauer and Scheerpeltz 1926
: 656. Holotype (female): Canada, British Columbia; Stickeen River Canyon;
Anepsiota wickhami
; Type USNM 39474, Casey bequest 1925 (USNM). Examined.
New locality data.
Canada: British Columbia: Mi. 56 Haines Hwy., Three Guardsmen Pass, 4.VII.1968, 3200 feet, J.M. Campbell and A. Smetana (1 ♂, CNC).
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.
The female holotype was captured in the Stickeen River Valley of British Columbia (
Casey 1894
), and one male was found in Three Guardsmen Pass, British Columbia.
