  Glypheoidea Information
The Glypheoidea (containing the glypheoid lobsters), is a group of lobster-like decapod crustaceans which forms an important part of fossil faunas, such as the Solnhofen limestone.
This group of decapods is a good example of a living fossil, or a lazarus taxon, since until their discovery in the 1970s, the group was considered to have become extinct in the Eocene.
The superfamily Glypheoidea comprises three families: the Glypheidae, Mecochiridae and Pemphicidae.

The Glypheoidea (containing the glypheoid lobsters), is a group of lobster -like decapod crustaceans which forms an important part of fossil faunas, such as the Solnhofen limestone.
Although the Glypheoidea was considered for a long time to be a purely fossil group, that opinion had to be altered when a single male specimen was discovered in the collections of the Smithsonian Museum.

They completely reject the inclusion of the glypheoids in the Palinura, corroborate their affinities with the Astacidea, and exclude the possibility that they would represent a primitive group from which other Reptantia could have evolved.
The lineage of the Glypheoidea most probably appeared in the Permian-Triassic, prospered in the Jurassic, and subsequently declined from the Cretaceous to the Eocene.
Elles rejettent totalement l'inclusion des Glypheoidea parmi les Palinura, insistent sur leurs affinités avec les autres Astacidea et écartent la possibilité qu'ils représentent un groupe primitif dont seraient issus d'autres Reptantia.

 Journal of Paleontology: A NEW FAMILY OF TRIASSIC LOBSTERS (DECAPODA: ASTACIDEA) FROM BRITISH COLUMBIA AND ITS ...
All three families of the superfamily Glypheoidea are firmly placed within the infraorder Astacidea, confirming the suggestion of Forest and de Saint Laurent (1989) and Martin and Davis (2001).
At node 41, the superfamily Glypheoidea is the sister group to erymoids and is defined by the presence of cephalic ridges (character 4[1]).
Chimaerastacus is a member of the monophyletic Glypheoidea, but lacks a laterally compressed carapace (character 1[0]), a postcervical groove (c) that arises from the branchiocardiac groove (a) (character 9[2]), and subchelae (character 13[1]) that make the family Glypheidae so distinctive.

Suborders Dendrobranchiata Pleocyemata Caridea Stenopodidea Reptantia The decapods or Decapoda are a group of crustaceans within the class Malacostraca, including many familiar groups of crustaceans, such as crabs, lobsters and shrimp, but also some families that are less well known.
Infraorders Caridea Stenopodidea Reptantia, divided into: Polychelida Achelata Glypheoidea Astacidea Thalassinidea Anomala Brachyura Pleocyemata is a sub-order of decapod crustaceans, erected by Martin Burkenroad in 1963.
Antennules Pereiopods Carapace Pleopods Uropods Telson The body of a decapod crustacean is made up of nineteen body segments grouped into two main body parts, the cephalothorax and the abdomen.

CenSeam researchers Bertrand Richer de Forges and Philippe Bouchet found a new species of shrimp while trolling an undersea plateau in a remote area between Australia and New Caledonia.
If you know French you can read Richer de Forges’ paper, Découverte en mer du Corail d’une deuxième espèce de glyphéide (Crustacea, Decapoda, Glypheoidea) [pdf] otherwise you can visit CenSeam’s site where he talks about the discovery.
The new species was named Neoglyphea neocaledonica which means essentially means “new Glyphea of New Caledonia”.

Homarida and Astacida are closely related, as shown by the unique process on the ischium of their first pereiopods.
Glypheoidea forms the sister group to Astacura, within an enlarged Astacidea.
Achelata is the sister group to Meiura (Anomala + Brachyura) in a new clade, Eurysternalia, characterized by a unique antennular morphology and by the eponymous wide sternum of its members.
