Diagnosis : Integument thin and fragile. Rostrum triangular, slightly concave and not reaching beyond the second segment of antennular penduncle. Carapace dorsally carinate. Eyes slightly narrower than eyestalks; ocular tubercle present on inner side of stalks; tip of the eye reaches to first segment of antennular peduncle. Branchiostegal spine minute, not supported by any carina, but showing a blunt ridge. Abdomen carinate on somites 4–6. Third abdominal somite with a very faint dorsal carina; median posterior tooth present on fourth, fifth and sixth somites. Telson longer than sixth somite, deeply sulcate dorsally (Modified from Kikuchi 1985 ). Distribution : Atlantic Ocean: Brazil (Fernando de Noronha Archipelago) . Pacific Ocean: Philliphines Sea and off Japan ( Kikuchi 1985 ; 1991 ) ( Fig. 20 ). Bathymetric distribution : 0–2394 m depth ( Kikuchi 1985 ; 1991 ), herein this species was found in Brazilian waters in depths between 130– 850 m . Remarks : The specimen analyzed herein agrees with the descriptions of Kikuchi (1985) based on specimens collected in Pacific Ocean. According to Kikuchi (1985) , the closest species of M. longisulca is M. mollis Smith, 1882 , however, these species differ from each other in the following way (character of M. mollis in parentheses): cornea of the eyes narrower than the eyestalks ( Fig. 19B ) (eyes much narrower than eyestalks); presence of blunt ridge which supports the branchiostegal spine ( Fig. 19A ) ( vs. branchiostegal spine supported by a short sharp ridge or carina); presence of dorsal carina on the third abdominal somite ( Fig. 19C ) ( vs. dorsal carina on the third abdominal somite absent). Meningodora longisulca was previously reported only from Pacific Ocean by Kikuchi (1985 ; 1991 ) ( Fig. 20 ), being recorded in few areas along the Philippines Sea and off Japan . In this paper, we report its first occurrence in Atlantic Ocean ( Brazil ), with the third observation of this rare species in all world.
