Vol. 104,No. 2,March &April, 1993 73 A RECLARIFICATION OF THE MALES OF ALLOPERLA CONCOLOR AND A. NEGLECTA (PLECOPTERA CHLOROPERLIDAE), WITH NEW DISTRIBUTION: RECORDS FOR BOTH SPECIES1 BorisC.

Adults ofthe genusAlloperla are generally recognized by theirdeli- cate habitus and lime green oryellowcoloration in vivo. Presently, this genus includes28Nearcticspecies. Manyofthesespeciesareregionally endemic and often are only locally abundant. Ricker (1935) described Alloperla concolor from Homing's Mills, Ontario,Canada based on a maleand two females. Prison, also in 1935 describedAlloperla neglecta from North Carolina nearNewfound Gap basedonthreemales.In 1942,PrisonsynonymizedA.concolor, aftercon- cludingthatthisspecieswas"specificallyidenticalwithneglecta."Ricker apparentlyconcurredwiththisopinion.However,Hitchcock(1968)pre- sented morphological evidence that Alloperla concolor was a valid species,basedontheshapeofthe maleepiproct. Heagain in 1974men- tioned that both species were specificallydistinct, based on the charac- ters of the epiproct, Surdick (1985) listed A. concolor as being north- eastern in distribution andA. neglecta restricted to the southern Appa- lachian Mountains ofNorth Carolina and Tennessee. After we collected specimens ofA. concolor from West Virginia in 1990, a reviewofthe taxonomic status ofboth species was undertaken. Types of both species were examined, but unfortunately the male terminalia ofthe holotype ofA. concolor had been lost (G. W. Wiggins, Royal Ontario Museum, personal communication).
