R. (R.) cylindricus LeConte, 1866 ( Fattig 1937; Bousquet 1990)

( Fig. 1B, D )

Habitat and Biology: An mostly Appalachian and central to southeastern species ( Bousquet 1990), R. cylindricus is found under bark of freshly fallen or dead standing pine trees, usually in association with bark beetles (including southern pine beetle). Adults are active during the fall, winter, and spring months in Georgia and across the eastern United States. Lindgren funnel traps baited with ethanol attract them in small numbers.
