REVISION OF THE NEARCTIC GENUS PSEUDACTIUM CASEY (COLEOPTERA, PSELAPHIDAE, EUPLECTINAE)

The genus Pseudactium Casey (=Racemia Newton and Chandler, new synonym y) is redescribed and shown to include ten species: three species prev iously placed in the genus-P. carolinae Casey (the type species), P. a rcuatum (LeConte) (lectotype designated), P. parabolicum (Brendel) (=R amecia dentiventris Casey, R. discreta Casey, P. mellinum Casey, and P . cephalicum Casey, new synonymies); Ramecia mendica Park, here moved to Pseudactium (new combination)-and six new species: P. alexanderi, P . copelandi, P. magazinensis, P. pecki, P. stannardi, and P. steevesi. Ramecia is redefined and its two species diagnosed: R. capitula (Case y) and R. crinita (Brendel). Pseudactium species, except P. stannardi (western Iowa), occur in deciduous forest habitats in eastern and sout heastern United States, with a concentration of species in Alabama. Se veral species appear to be restricted to old growth deciduous forests.
