F936C54E0A52FFEE8388F31BFB7F9CB2.taxon	discussion	Remarks. As noted by Lowry & Stoddart (1994: 144) there is very little difference between Clepidecrella and Kerguelenia. However the two genera can be consistently distinguished by the presence of a vestigial incisor in Clepidecrella and the complete absence of an incisor in Kerguelenia. Apart from one species (C. tropicalis) Clepidecrella species have a short ischium on gnathopod 1 (length less than 2 x breadth) whereas all Kerguelenia species have a long or very long ischium (length up to 4.8 x breadth). Clepidecrella now contains 6 species: Clepidecrella cabinda J. L. Barnard, 1962; C. abeona sp. nov.; C. cataraqui sp. nov.; C. colliboi sp. nov.; C. ira sp. nov.; C. tropicalis Lowry & Stoddart, 1994	en	Lowry, J. K., Stoddart, H. E. (2010): Kergueleniidae fam. nov.

F936C54E0A52FFEE8388F6BCFB399E91.taxon	discussion	Remarks. Kergueleniids have lost many of the morphological markers that would indicate relationships to other lysianassoid families, but the group has some morphological similarities to endevourids and lysianassines. Kergueleniids differ most obviously from endevourids in having simple third pereopods. Kergueleniids may be most similar to lysianassines. Both have simple first gnathopods, large first coxae and a well developed posteroventral lobe on coxa 4. Kergueleniids differ from lysianassines in the extremely reduced (in both number and size) setal-teeth on maxilla 1 and in the extremely reduced plates on the maxilliped. Kergueleniids differ from taxa such as Lepidepecreella Schellenberg, 1926 and Izinkala Griffiths, 1977, which also have very reduced mouthparts, in having coxae 1 to 4 well developed.	en	Lowry, J.

F936C54E0A51FFEA8388F403FC3D9B89.taxon	discussion	Remarks. Clepidecrella abeona is similar to the two previously described species, C. cabinda and C. tropicalis, in having a lacinia mobilis on the left mandible and 6 setal-teeth on maxilla 1 outer plate. It differs from these two species in not having a molar and having a narrowly rounded posteroventral corner on epimeron 3. It differs from all other Clepidecrella species in having a gnathopod 1 basis expanded midanteriorly. The holotype female has long oostegite buds on gnathopod 2 and pereopods 3 to 5. It is the only species we have seen with a full complement of oostegites.	en	Lowry, J. K., Stoddart, H. E. (2010): Kergueleniidae fam. nov.
