Pleopod biramous; exopod with one long feathered seta. Uropod biarticled; exopod and endopod composed of two articles; exopod shorter then first article of endopod.</p> <p>Ovigerous females: as non­ovigerous females, body flattened dorsoventrally with marsupium, composed of four oostegites originated at pereopod 1 to 4.</p> <p>Neuter: as non­ovigerous female.</p> <p>Juvenile males: as non­ovigerous females except antennule with five articles and cheliped ornamentation (crenulation, tubercles) more prominent.</p> <p>Males: antennule with seven articles. Inner margin of chela with a row of simple setae near insertion of dactylus. Pleopods well developed, pleon almost as long as pereon.</p> <p>Type species: Paraleptognathia typica Kudinova­Pasternak, 1981, original designation.</p> <p>Included species: in addition to the type species are: Paraleptognathia alba (Hansen, 1913), P. antarctica (Vanhöffen, 1914), P. australis (Beddard, 1886), P. bacescui Kudinova­Pasternak, 1985, P. benguela n. sp., P. bisetulosa Dojiri &amp; Sieg, 1997, P. brachiata (Hansen, 1913), P.fastuosa n. sp., P. gracilis (Krøyer, 1842), P.inermis (Hansen, 1913), P. longiremis (Lilljeborg, 1864), P. multiserrata (Hansen, 1913), P. multiserratoides n. sp., P. tenuichela n. sp., P. weddellensis (Sieg, 1986).</p> <p>Remarks: the revision of the genus Paraleptognathia became necessary due to an observation made during the analysis of more than two thousand Tanaidacea from Greenland in 2003. Up to now Akanthophoreus and Paraleptognathia were recognized as valid genera. It was suspicious that in the studied material an undescribed species of Paraleptognathia was always found together with ” Akanthophoreus gracilis ”. Both species were very similar, sharing the same identification characters; the only difference was the five articles in antennule, and better expressed crenulation of cheliped and bigger tubercles in Paraleptognathia than in Akanthophoreus. Previous studies were bringing suspicious results: ovigerous females and mancas of Paraleptognathia were always absent in samples, although this species was sometimes very abundant, these findings were never explained. Further observation displayed that one non­ovigerous female of the new ” Paraleptognathia ” species from Greenland had a small genital cone. Hansen (1913) mentioned that the preparatory males of Leptognathia hanseni Vanhöffen, 1907 had five segments on the antennule. These facts led to a more detailed comparison of the two genera. After examining a male of ” Akanthophoreus gracilis ” and comparing it with the new Paraleptognathia species it was clear that this ” Paraleptognathia ” is a preparatory male of Akanthophoreus gracilis. This assumption led to the comparison of the rest of ” Akanthophoreus ” and ” Paraleptognathia ” species, Paraleptognathia antarctica and Akanthophoreus antarcticus, were sympatric and shared the same diagnostic characters. In samples with A. weddellensis or A. australis were always Paraleptognathia specimens that differs only in the number of articles in the antennule. After all these observations it has become clear that the genera Paraleptognathia and Akanthophoreus were synonyms. The discovery of unpublished notes of Jürgen Sieg deposited in the Zoological Museum Berlin (collection of Dr. O. Coleman) confirmed this observation.</p> <p>Paraleptognathia was described by Kudinova­Pasternak in 1981 and has priority over Akanthophoreus Sieg, 1986. Therefore Akanthophoreus is a junior synonym of Paraleptognathia.</p> </div>	http://treatment.plazi.org/id/03FB8794FFBBB317E927080AFE1DFBD2	Public Domain	No known copyright restrictions apply.

From the original illustration (Kudinova­Pasternak 1985:56) and description can be concluded that the specimens are 1.2–3.6 mm long. Mancas are between 1.2 and 1.6 mm long. The antenna is composed of seven articles; article 4 is divided in two. In the investigated material from other Paraleptognathia species it cannot be seen. Some individuals show a constriction at this level but it is not clear if the article is only damaged. Kudinova­Pasternak (1985) mentions that the palp of the maxillula has only one terminal filament. The cheliped is covered by very fine setules. This could not be observed in any other Paraleptognathia. The illustration of the cheliped is difficult to compare to other species because it displays the inner side while most of the other illustrations show the outer side of the cheliped. The carpal shield is well developed, making the carpus almost as long as wide. The row of setae on the propodus of the cheliped is present in many adult females as well in many adult males of Paraleptognathia and Leptognathia species (Dojiri &amp; Sieg 1997).</p> <p>This species is closely related to P. benguela n. sp. A better separation of these two species will not be possible before more material of P. bacescui is available.</p> </div>	http://treatment.plazi.org/id/03FB8794FFA8B30BE9270812FB19FE01	Public Domain	No known copyright restrictions apply.

There are numerous population that show a wide range of variation in the size of the lateral pleotelson apophyses, in the size of cheliped carpal shield, and chela crenulation. Some specimens from Iceland, Greenland and Spitzbergen possess large lateral apophyses on the pleotelson. Preparatory males from west and south Greenland posses small lateral apophyses on the pleotelson and a moderated developed carpal shield and some individuals show a weak lateral crenulation on the fixed finger as in P. australis. In the Mellemfjord (west Greenland) individuals stages with short, middle and large apophysis, as well as with lateral crenulation on the fixed finger, and moderated developed carpal shield of the cheliped were found. Some large non­ovigerous females possess also crenulation on the fixed finger but no pleonal apophysis. The observed variability of these characters support the assumption of Lang (1957) making Leptognathia sarsii Hansen, 1909 a synomym of P. gracilis.</p> <p>The carpal shield in P. gracilis is moderated to weak developed which makes it easy to distinguish from other Paraleptognathia species of the Arctic. Adult males are very scarce, from 1314 individuals of the Mellemfjord examined only 2 were adult (”swimming”) males.</p> <p>Reports of P. gracilis from the Southern Ocean must be attributed to other species like P. australis or P. antarctica.</p> </div>	http://treatment.plazi.org/id/03FB8794FFA4B303E92708F8FDD3FE01	Public Domain	No known copyright restrictions apply.
