Egg morphology and classification of Perlodinae (Plecoptera : Perlodidae)

Abstract

A new classification of Perlodinae (sensu Zwick 1973) is proposed in which three tribes are recognized. Arcynopterygini Ricker & Scudder includes genera whose eggs are circular in cross section while Perlodini Klapálek and Diploperlini, new tribe, include genera whose eggs are triangular or semicircular in cross section.
