Perlesta adena Stark 1989:277  . Holotype ♂ ( USNMAbout USNM), Stillwater River , Miami Co., Ohio. 

Perlesta adena: Stark 2004:90 

Distribution. USA: IN, KY, OH, TN ( DeWalt et al. 2018)

Remarks. Males and females of P. adena  have a dark head mask ( Figs. 1a‒1f View Figure ) that is superficially similar to P. xube  ( Figs. 2a‒2e View Figure ), but easily distinguished from sympatric populations of P. armitagei  sp. nov. from Indiana, Kentucky, and Ohio ( Figs. 6a‒6f View Figure ). Published line drawings of the aedeagi of P. adena  ( Stark 1989, his Fig. 76, Stark 2004, his Figs. 273‒274) and P. xube  ( Stark and Rhodes 1997, their Fig. 6 View Figure , Stark 2004, his Figs. 370‒371) make it easy to differentiate between males of these two species.

Females of P. adena  and P. xube  are difficult to separate due to subtle characteristics of their subgenital plates ( Stark 2004). Eggs are likewise superficially too similar in appearance even with SEM to differentiate to species ( Stark 2004, his Fig. 7.400 for P. adena  and Fig. 7.404 for P. xube  ).

Perlesta adena  and P. xube  overlap in distribution mainly in Ohio ( Fig. 11a View Figure ). Perlesta adena  is distributed in the lower Ohio River, Cumberland River, and Tennessee River basins plus a few Lake Erie drainages in northern Ohio ( Fig. 11a View Figure ).
