ABSTRACT
Fourteen species of Liogluta Thomson are reported from Canada and Alaska. Three of these are described as new to science: Liogluta castoris Klimaszewski & Webster, sp. n.; Liogluta microgranulosa Klimaszewski & Webster, sp. n.; and Liogluta pseudocastoris Klimaszewski & Webster, sp. n. The previously unknown male of Liogluta gigantea Klimaszewski & Langor, Liogluta quadricollis (Casey), Liogluta wickhami (Casey), and female of Liogluta granulosa Lohse are described, and illustrated. Liogluta aloconotoides Lohse is synonymized with Liogluta terminalis (Casey). New provincial and state records are provided for six Liogluta species. A key to species, revised distribution with new provincial records, and new natural history data are provided.

No MeSH data available.


Lioglutaquadricollis (Casey): 16 habitus in dorsal view 17 median lobe of aedeagus in lateral view 18 male tergite VIII 19 male sternite VIII [16–19 based on male from BC] 20 female tergite VIII 21 female sternite VIII 22 spermatheca (19–22 based on female holotype). Scale bar of habitus = 1 mm, remaining scale bars = 0.2 mm.

Figure 3: Lioglutaquadricollis (Casey): 16 habitus in dorsal view 17 median lobe of aedeagus in lateral view 18 male tergite VIII 19 male sternite VIII [16–19 based on male from BC] 20 female tergite VIII 21 female sternite VIII 22 spermatheca (19–22 based on female holotype). Scale bar of habitus = 1 mm, remaining scale bars = 0.2 mm.

Mentions: Body length ranging from 2.8–5.4 mm, body narrowly subparallel (Figs 1, 8, 16, 23, 30, 35, 44, 50, 58, 65, 72, 79, 86, 90), moderately flattened; elytra and abdomen wider than head and pronotum; uniformly dark brown or reddish-brown with head and posterior abdomen dark brown to almost black; integument of forebody with strong meshed microsculpture; surface of elytra often granulose (Figs 50, 51); head with incomplete postocular carinae, postocular region of head long and in most species longer than diameter of eye; glossae split into two lobes; antennae long with articles VI-X subquadrate, slightly transverse or rarely slightly elongate; pronotum with hypomera fully visible in lateral view; pubescence of pronotum directed posteriad on midline of disc and posterolaterad to laterad on sides; mesocoxae narrowly separated, metasternal process short and acute; legs long, three basal articles of metatarsi highly elongate in most species; tarsal formula 5-5-5. Male. Apical margin of male tergite VIII often with broad, variably-shaped rectangular projection, with edge entire or bearing crenulation or variably shaped structures, with two lateral teeth and sometimes with additional median tooth; integument of disc often with broadly distributed asperate punctation near apex (Figs 3, 11, 18, 25, 38, 46, 53, 60, 67, 74, 81, 88, 92); median lobe of aedeagus simple with apical part variably shaped in lateral view (Figs 2, 9, 17, 24, 36, 45, 52, 59, 66, 73, 80, 87, 91). Female. Spermatheca with capsule narrowly club-shaped or tubular, with apical invagination moderate to deep, stem long, sinuate, looped or twisted posteriorly (Figs 7, 15, 22, 29, 34, 42, 43, 57, 64, 71, 78, 85, 96); sternite VIII with apical margin rounded or medially emarginate, antecostal suture arcuate, or slightly to distinctly sinuate (Figs 6, 14, 21, 28, 33, 41, 49, 56, 63, 70, 77, 84, 89, 95).
