Infraorder of arthropods
Diploperculata is an infraorder of eurypterids , an extinct group of aquatic arthropods commonly known as "sea scorpions". The name, derived from Greek διπλόω ("double") and operculum , refers to the distinguishing feature that unites the superfamilies included in the group, that the genital operculum is made up of two fused segments.[ 1]
The group contains the three eurypterine superfamilies Carcinosomatoidea , Adelophthalmoidea and Pterygotioidea alongside the as of yet undescribed "waeringopteroid " clade.[ 2] The diploperculate eurypterine clade had prior to its description been noted as a monophyletic group of derived eurypterines that form a sister-taxon to the superfamily Eurypteroidea .[ 3]
