The imagos of some enigmatic members of theHermanellacomplex (Ephemeroptera, Leptophlebiidae).
The imago stages of three species of theHermanellacomplex are described mostly based on material from Roraima, northern Brazil:Hydrosmilodon gilliesae,Hydromastodon sallesiandLeentvaaria palpalis. Male imagos ofHydrosmilodon gilliesaeandLeentvaaria palpalisboth have a pair of large, broad projections at the posterior margin of the styliger plate, nearly covering the penis lobes; inLeentvaaria palpalis, however, these projections are fused. The male imago ofHydromastodon sallesiresemblesHydrosmilodon plagatusin that both species have a styliger plate with a robust projection that is curved towards the penis lobes. DNA barcoding is likely to be a powerful investigative tool for identifying and understanding species limits among these Ephemeroptera taxa, especially if it is used within an integrative taxonomic context. An updated identification key to the genera of theHermanellacomplex is proposed.
