Topic: Phyllocarida


In the News (Sat 26 Dec 09)

  
  Marine Phyla Pages
Malacostraca can be divided into two groups, the Phyllocarida and the Eumalacostraca.
Phyllocarida contains the oldest crustacean known and includes only one living group.
The Eumalacostraca consists of all Malacostracan groups other than the Phyllocarida.

 Crustacea Info
When one thinks of a crustacean he or she most often thinks about one of the more than 30,000 species in this group.
This class is is split into three subclasses, Phyllocarida, Hoplocarida (stomatopods), and Eumalacostraca (mainly peracarids and decapods).
The subclass Phyllocarida is thought to represent the primitive malacostracan condition by having 7 instead of 6 abdominal somites (plus telson), and serially repeated, paddle-like, biramous (two branched) appendages.

 THE SEARCH FOR ROOTS: PALAEOPEMPHIX IS NOT A DECAPOD   (Site not responding. Last check: 2007-11-01)
This combination of characters is decidedly unlike the morphology of known decapod crustaceans and more closely resembles the attributes of the Phyllocarida, a diverse group of malacostracous crustaceans known from Cambrian to Recent occurrences.
Within the Phyllocarida, Palaeopemphix appears to represent a new suborder.
Thus, the search for the roots of the Decapoda lies elsewhere.

 CSIRO PUBLISHING - Books & CDs
The volume opens with a general introduction to the Malacostraca, giving an historical overview of the work on this group.
The Catalogue then summarises the baseline data on nomenclature and taxonomy of all Phyllocarida, Hoplocarida and Eucarida (with the exception of crabs, hermit crabs and their allies).
For each family there is a brief introduction and diagnosis, then Australian species are cited by name and original references are given.

 ADW: Malacostraca: Information
The head and thorax are fused into a cephalothorax and may be difficult to distinguish.
All malacostracans possess five segments in the head, eight in the thorax, and six in the abdomen, excepting the 20-odd species in the Phyllocarida, which have seven abdominal segments.
As a general rule, each segment bears a pair of appendages, but in some organisms appendages are lacking on several abdominal appendages.

Some of the major questions about the relationships within the Malacostraca are: Is the Leptostraca the sister group to the rest of the Malacostraca?
What is the relationship between the five major groups (Hoplocarida, Phyllocarida, Syncarida, Peracarida, and Eucarida) within the Malacostraca?
We will present 18S and partial 28S rDNA data to help answer some of these questions.

Nahecaris Jaekel, 1921 (Malacostraca, Phyllocarida, Archaeostraca): proposed precedence over Dilophaspis Traquair in Walther, 1903
The purpose of this application, under Articles 23.9.3 and 81.2.3 of the Code, is to conserve the generic name Nahecaris Jaekel, 1921 for a group of Lower Devonian phyllocarid crustaceans (order Archaeostraca) by giving it precedence over the older name Dilophaspis Traquair in Walther, 1903 whenever the two names are considered to be synonyms.
