Comments.

This is the first record of Parocyusa americana since its description based on a female specimen collected from Peekskill, New York ( Casey 1906). This species is easily recognized to genus by its habitus and 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 8-10 (see Fig. 28 in Klimaszewski et al. 2011). To promote nomenclatural stability, we designate a lectotype for Parocyusa americana here.

Specimens of Parocyusa americana were found on a stream bank and in a dry streambed under a rock. We expect Parocyusa americana to occur broadly over northeastern North America in habitats near running water.
