Neoglyphea

Neoglyphea inopinata is a species of glypheoid lobster, a group thought long extinct before Neoglyphea was discovered. It is a lobster-like animal, up to around 15 centimetres (5.9 in) in length, although without claws. It is only known from 17 specimens, caught at two sites – one at the entrance to Manila Bay in the Philippines, and one in the Timor Sea, north of Australia. Due to the small number of specimens available, little is known about the species, but it appears to live up to five years, with a short larval phase. A second species, previously included in Neoglyphea, is now placed in a separate genus, Laurentaeglyphea.

Taxonomy

Neoglyphea inopinata was named in 1975 by Jacques Forest and Michèle de Saint Laurent of the '' in Paris. It was based on a single damaged specimen that had been caught by the USFC Albatross in the Philippines in 1908, and deposited in the United States National Museum. De Saint Laurent examined the unidentified specimen while working on Thalassinidea at the Smithsonian Institution. The name Neoglyphea means "new Glyphea", while the specific epithet '' means "unexpected". A second extant species of glypheoid was originally placed in the genus Neoglyphea as Neoglyphea neocaledonica, but was later split into a separate genus, Laurentaeglyphea. ==Significance==

Significance

Until the discovery of Neoglyphea, the Glypheoidea was thought to have died out before the end of the Eocene, . They had been thought to be closely related to spiny lobsters and slipper lobsters, with which they formed the group "Palinura". Study of non-fossil specimens made it apparent that the similarities between the two groups resulted from analogy, rather than homology, and that Glypheoidea was closer to lobsters and crayfish. Glypheoidea is occasionally included within the infraorder Astacidea, but molecular analysis using the DNA of Neoglyphea and Laurentaeglyphea suggest that it is better placed as a separate infraorder, Glypheidea. ==Distribution==

Distribution

Neoglyphea has been caught in two distantly separated geographical areas. The initial specimens were from a small area at the entrance to Manila Bay at depths of . Three additional specimens have been recovered from a locality in the Timor Sea (near ) at a depth of . ==Description==

The overall length of the known specimens of Neoglyphea varies from to . ==Ecology==

Ecology

Neoglyphea appears to be most active during the daytime, since most of the known specimens were captured close to midday. ==References==
