Aleochara (Xenochara) inexpectata Klimaszewski Figs 1-7

Diagnosis.

Body length 3.0-6.5 mm, piceous-to-black, with tarsi, last articles of labial and maxillary palpi and often posterior margin of elytra rust-brown (Fig. 1). This species is externally very similar to Aleochara lanuginosa Gravenhorst from which it differs by the shape of the sclerites of the internal sac of the aedeagus (Fig. 2), the shape of the spermatheca (Fig. 7), and the smooth apical margin of male tergite VIII (Fig. 3). For a more detailed description, see Klimaszewski (1984).

Distribution.

Bionomics.

In Newfoundland, adults were collected in moose dung near a bog, and in bear and sheep/horse dung. In New Brunswick, adults were captured from fresh moose dung in an eastern white cedar swamp and in decaying sea wrack resting on vegetation on the upper margin of a salt marsh ( Webster et al. 2009). The adults were collected from May to July.
