Diagnosis.

This species is easily recognized to genus by the shape of its habitus with subparallel body, deeply impressed and coarsely punctate first three visible abdominal tergites, elongate pronotum, very long tarsi with hind tarsi almost as long as tibia (Fig. 31), and the shape of spermatheca (Figs 34). The only other known Nearctic species, Parocyusa fuliginosa  (Casey), is darker, with a slightly shorter and more densely punctate pronotum, and has quadrate to slightly transverse antennomeres VIII-X (see Fig. 28 in Klimaszewski et al. 2011).

Distribution.

Bionomics.

In Newfoundland, one female was captured in a pitfall trap in September from a coniferous forest. In Ontario, females of Parocyusa americana  were found on a stream bank and in a dry stream bed under a rock ( Brunke et al. 2012).

Comments.

This is the second record of this species from Canada, and it is much further east than the first record from Ontario by Brunke et al. (2012). We expect Parocyusa americana  to occur broadly over northeastern North America in riparian habitats. At both Canadian localities only females were captured, and the original description is also based on a female specimen captured in Peekskill, New York ( Casey 1906).
