Ordo: Coleoptera
Familia: Staphylinidae
Genus: Acrotona
Name
Acrotona horwoodae Klimaszewski & Godin sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Holotype
(male). Canada, Yukon, Whitehorse, Paddy’s Pond, 60.7067, -135.0917, 27.V.2008, 649 m, litter sifting, mixed aspen and white spruce forest, B. Godin (LFC).
Paratype
(female). Same data as the holotype (ECW).
Etymology
This species name is dedicated to Denise Horwood, wife of the second author, who assisted him in numerous aleocharine sample collections.
Diagnosis
Body narrowly oval, moderately convex, uniformly black, punctation on forebody fine, dense and not asperate, microsculpture fine but not pronounced; length 2.4 mm; head narrower than pronotum, ratio of maximum width of head to maximum width of pronotum 0.7; antennal articles 7–10 slightly transverse; pronotum moderately transverse, ratio of maximum width to length 1.4, about as wide as elytra; elytra at suture about as long as pronotum; abdomen slightly narrowed posteriad (Fig. 4). MALE: tergite 8 moderately elongate and truncate apically (Fig. 34); sternite 8 widely arcuate apically (Fig. 35); median lobe of aedeagus as illustrated (Fig. 17). FEMALE: tergite 8 moderately elongate and truncate apically, base not sinuate (Fig. 36); sternite 8 widely arcuate apically, base not sinuate (Fig. 37); spermatheca with capsule tulip-shaped and stem coiled posteriorly (Fig. 18).
Bionomics. The specimens were found by sifting forest litter in May.
Comments. The shape of the median lobe of the aedeagus and the spermatheca of Acrotona horwoodae are different from all recorded species of Nearctic Acrotona, and they are generally similar to those of the Palaearctic species Acrotona aterrima Gravenhorst, which is brown and has a much broader body.
