Glypheidea

Glypheidea belongs to the clade Reptantia within the order Decapoda, although its exact placement within Reptantia is difficult to determine. Some phylogenetic studies consider Glypheidea to be most closely related to the infraorder Astacidea, which consists of the lobsters and crayfish, whereas other studies instead consider Glypheidea to be more closely related to the infraorder Polychelida, a group of deep-sea blind lobsters. ==Taxonomy==
