Aleochara (Aleochara) tahoensis Casey View in CoL Figs 8-14

Diagnosis.

Body length 4.5-7.0 mm, robust, dark brown to black, with legs, labial and maxillary palpi and most of elytra (except for scutellar section) rust-brown (Fig. 8); maximum distance between eyes equal to 2.5 times maximum diameter of eye (Fig. 8). This species is externally very similar to Aleochara gracilicornis Bernhauer from which it differs by having a wider distance between eyes (2.0 times maximum diameter of eye in Aleochara gracilicornis ). It may be distinguished from all species of Aleochara by the shape of median lobe and the sclerites of the internal sac of the aedeagus (Fig. 9), and the shape of the spermatheca (Fig. 14). For a more detailed description, see Klimaszewski (1984).

Distribution.

Bionomics.

In Newfoundland, adults were collected from among beach rocks and detritus. Elsewhere, adults were captured from flood debris, swampy areas, debris around dead elm and from a moose carcass ( Klimaszewski 1984). Most specimens collected in southwestern USA were found at high altitudes up to 2438 m. The adults were collected from May to September.
