Liogluta terminalis (Casey, 1906)  Figs 1-7

Anepsiota terminalis  Casey, 1906: 339. As Atheta (Liogluta)  : Bernhauer and Scheerpeltz 1926: 658 (as syn. of Atheta renominata  ). Holotype (female): Canada, British Columbia, Glenora, Wickham; terminalis  Casey; Type USNM 39472; Casey bequest 1925; Liogluta terminalis  (Casey) V.I. Gusarov 1998; cf. Liogluta aloconoides  ( USNM). Examined.

Atheta (Liogluta) renominata  Bernhauer & Scheerpeltz, 1926: 658 (nom. nov. for Anepsiota terminalis  Casey, 1906 in Atheta  , not Atheta terminalis  Gravenhorst, 1806 and Gyllenhal, 1810; synonymized by Seevers 1978).

Liogluta (Anepsiota) aloconotoides  Lohse, in Lohse et al. 1990: 165. New synonymy. Holotype (male): Canada, Labrador, L’Anse au Loup, 9.VIII.1972, J.M. Campbell ( CNC). Paratypes: Canada, Labrador, Red Bay, 8.VIII.1972, J.M. Campbell (5, sex undetermined, CNC).

New locality data.

USA: Montana: Flathead Co., Glacier National Park, N Fork Flathead area, 1988, Red Bench Fire study; N Mud Lake, 3520 feet, lodgepole unburned T34N, R21W, Sec 1, 7.VI.1990, pitfall trap, M.A. Ivie (1 ♀, LFC). New Hampshire, Coos Co., Hwy. 16, 5-6 km S Gorham, 9.IX.1987, A. Smetana (1 ♂, 2 ♀, CNC).


This species may be distinguished by the following combination of characters: body subparallel, entirely reddish-brown or with head and posterior abdomen chestnut brown (Fig. 1); length 3.9-4.5 mm; integument of forebody with meshed microsculpture, moderately glossy; head about one-quarter narrower than maximum width of pronotum; pronotum transverse, narrower at base and widest in apical third; elytra at suture about as long as pronotum; basal three articles of metatarsus elongate, first longest, second about as long as third, fourth shorter than either of preceding articles; apical margin of male tergite VIII with broad, short, truncate projection with rounded lateral angles, apical margin smooth or slightly crenulate (Fig. 3); female tergite VIII with apical margin broadly, just visibly emarginate (Fig. 6); genital structures as illustrated (Figs 2, 7).

Natural history.

Klimaszewski et al. (2011) reported this species (as Liogluta aloconotoides  ) from various forest types and on coastal limestone barrens in Newfoundland. Specimens from New Brunswick were collected from dung in a coastal red spruce forest, by treading sedges along a small lake margin, from a Lindgren funnel trap deployed in a rich Appalachian hardwood forest with some conifers, and from a pitfall trap ( Webster et al. 2012). In Alberta, adults were reared from well-decayed white spruce logs ( Klimaszewski et al. 2015). Elsewhere, adults were captured in various forest types including a recently burned forest. The type specimens of Liogluta aloconotoides  were captured in August ( Lohse et al. 1990). Klimaszewski et al. (2015) reported adults from July to October.


Recorded from LB, NB, NF, NS, ON, QC, AB, YT, and BC ( Casey 1906, Lohse et al. 1990, Klimaszewski et al. 2008, Majka and Klimaszewski 2008, Klimaszewski et al. 2011, Webster et al. 2012, Bousquet et al. 2013, Klimaszewski et al. 2015), and newly in USA from MT and NH.


We have examined the female holotype of Liogluta terminalis  (Casey) from Glenora, British Columbia, and compared it with the specimens of Liogluta aloconotoides  Lohse east of the Rocky Mountains. We found no external or genital differences between the holotype of Liogluta terminalis  and the other female specimens identified as Liogluta aloconotoides  and therefore we consider Liogluta aloconotoides  as a new synonym of Liogluta terminalis  .
