Paraleptognathia bacescui Kudinova­Pasternak, 1985

Material examined: none.

Distribution: this species is only known from the type locality RV ”Vitjaz” 1982, St. 163, 29° 51.0´N 28° 07´W, 3340–3440 m depth.

Remarks: the type material could not be found in the Zoological Museum of Moscow (Blazewicz­Paszkowycz, personal communication). 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 & Sieg 1997).

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.
