Epistome and upper lip not differentially produced; mandibular 

 molar small but distinct, possibly triturative, palp attached over 

 proximal end of molar; gnathopod 1 simple, rather stout, article 6 

 slightly longer than 5; article 2 of outer ramus on uropod 3 minute; 

 telson short, entire. Merges with some species of Menigrates. Species : 

 1, subarctic, littoral.

Upper lip and epistome not described; mandible lacking molar in 

 type-species or bearing conical setulose lamina in other species; 

 palp attached rather distally; inner plate of maxilla 1 densely setose, 

 with 10 or more setae {combining character); gnathopod 1 subchelate, 

 article 6 slightly longer than 5, article 3 elongate, nearly as long as 

 article 6 (Aristias, Eurythenes) ; telson of medium length, deeply 

 cleft. Species: 4, Atlantic-Pacific, bathyal-abyssal. 



Paralysianopsis Schellenberg

 Austronisimus K. H. Barnard, 1931. 



Type-species: P. odhneri Schellenberg, 1931 (monotypy). 



Upper Up produced acutely in front of epistome, but almost fully 

 coalesced with epistome; mandibular molar obsolescent, palp attached 

 slightly proximal to molar; gnathopod 1 nearly simple, with minute 

 oblique palm; inner ramus of uropod 2 constricted; telson entire, 

 mth minutely notched apex. Species: 1, subantarctic, Uttoral. 



Paramhasia Walker and Scott 



Parambasia Walker and Scott, 1903. 



Type-species: P. /orfeesi Walker and Scott, 1903 (monotypy). 



Diagnosis based partially on P. rossi Stephensen (1927) assuming 

 it to be congeneric. [Epistome and upper lip poorly known], probably 

 fused together; mandibular molar small, setulose, palp attached 

 proximal to molar; gnathopod 1 simple, article 5 slightly longer than 

 article 6 ; inner ramus of uropod 2 constricted (possibly not on type) ; 

 outer ramus of uropod 3 uniarticulate; telson entire. Species: 2, 

 Arabian Sea, Auckland Islands, httoral. Possibly congeneric: Lysi- 

 anassa anomala Nicholls, 1938, subantarctic.
