First report of aberrant sperm in Edessinae and analysis of the male reproductive system of Edessa rufomarginata (De Geer, 1773) (Hemiptera: Pentatomidae).

Edessinae is one of the ten subfamilies of Pentatomidae, and it is further divided into seven genera. Among these, Edessa Fabricius, 1803 is the most diverse genus, boasting around 300 species recognized for their ecological and economic significance worldwide. The inclusion of various pentatomids in the Edessa genus has led to mistakes in its taxonomy due to common morphological features and misidentifications.
