| Distribution of Cordulegastroidea | |
Cordulegastroidea is a superfamily of dragonflies comprising the families Chlorogomphidae, Cordulegastridae and Neopetaliidae.[2][3]
The superfamily includes both living and extinct lineages, with fossils known from the Late Jurassic (possibly) and the Early Cretaceous.[4][5]
Taxonomic history
The superfamily Cordulegastroidea was established by Hagen in 1875.[3]
Modern classifications recognise three extant families within the superfamily: Chlorogomphidae, Cordulegastridae and Neopetaliidae.[2][3]
The fossil clade Chlorogomphida, proposed by Bechly in 1996, broadly corresponds to Cordulegastroidea and related extinct stem groups.[3]
Phylogeny
Phylogenetic studies generally support Cordulegastroidea as a monophyletic group comprising Chlorogomphidae, Cordulegastridae and Neopetaliidae.[3][6][7]
Within modern dragonflies, Cordulegastroidea is generally recovered as the sister group to Libelluloidea.[3][6]
Families
The following families are currently placed in Cordulegastroidea:[2][3]
- Chlorogomphidae Needham, 1903
- Cordulegastridae Hagen, 1875
- Neopetaliidae Tillyard & Fraser, 1940
Fossil record
The oldest confirmed fossils assigned to Cordulegastroidea belong to the extinct families Mesochlorogomphidae and Araripechlorogomphidae, which are regarded as close relatives of the Chlorogomphidae.[4][5]
The family Hemeroscopidae, may also belong to this lineage, but its placement remains uncertain.[8]
Etymology
The superfamily name Cordulegastroidea is derived from the type genus Cordulegaster and the zoological suffix -oidea, used for superfamilies.
The genus name Cordulegaster is presumably derived from the Greek κορδύλη (kordylē, "club") and γαστήρ (gastēr, "belly" or "abdomen").[9]
