A NEW STONEFLY SPECIES (PLECOPTERA: PERLIDAE) FROM SOUTHERN USA, WITH MORPHOLOGICAL AND MOLECULAR COMPARISON TO OTHER TAXA
A new species of Perlesta Banks, temporarily named AR-1, is described from male, female, and egg stages. The absence of an earlier description is highly unexpected given AR-1's conspicuously distinct aedeagal morphology and prevalence in a widely distributed and previously sampled area. AR-1, present in at least five counties in western Arkansas, is differentiated from other cogeners by the presence of a ventral caecum and a large basal dorsal spinulae patch of the aedeagus. Comparisons to 15 cogeners and two outgroup taxa are made with morphological and cytochrome c oxidase subunit I barcoding fragment data. Stereomicroscope and scanning electron micrograph images are provided.
