A new stonefly species (Plecoptera: Perlodidae) from Eocene Baltic amber and questions on the wing venation potential for species diagnostic of fossil Plecoptera
Keyword(s):
Examination of Baltic amber Plecoptera reveals a new species of Isoperla: Isoperla baltica sp. nov. The placement of this new species is supported by an in-depth comparison of apomorphies supporting families, subfamilies, and suborders. Contrary to previous descriptions of many fossil species, we took advantage of the good preservation of the genitalia to describe and compare this new species to its extant congeners. Finally, we discuss the usefulness and limitations of relying on wing venation to identify diagnostic characters in Plecoptera by figuring a specimen of Pteroliriope sinitshenkovae Cui, Béthoux, Kondratieff, Shih & Ren, 2016 with numerous crossveins and an original organization of forewing veins.
