Recognition characters

Carapace with margins arched, almost as wide as long. Outer orbital spine followed by 5 lateral spines. Gastric area with 1 pair of epigastric spines. One parahepatic spine on each side of carapace. Branchial and hepatic areas unarmed. One cervical spine on each side of carapace. Cardiac area with 1 central spine above mesocardiac groove. Several spines in posterior branchial area. Posterior margin of carapace with 1 pair of spines. Remainder of carapace unarmed. Rostrum short, length similar to supraocular spines. Abdominal tergites 2 and 3 with anterior margin armed with 4 spines each; abdominal tergite 4 with 2 or 4 spines on anterior margin. Peduncle of antennule with outer terminal spine much longer than inner one. Peduncle of antenna with only segment 2 armed, with 1 inner and 1 outer spine. Third maxilliped with 1 strong spine on ventral (flexor) margin of merus. Ambulatory legs characteristically long, their lengths similar to that of cheliped. Distribution

Western Atlantic: Virginia, Carolinas, Gulf of Mexico (south and north coast), Bahamas, Cuba (north and south coast), Cay Sal Banks, Puerto Rico, Lesser Antilles ( St. Kitts, Dominica, St. Lucia, Barbados), Mexico, Venezuela, Guiana and Brazil (São Paulo, Santa Catarina, Rio Grande do Sul); 129–729 meters depth. According to Wenner (1982), this species is most abundant between 200 and 400 meters.

Remarks

Agononida longipes is an easily recognizable species, possessing a wide carapace, short rostrum and legs as long as the chelipeds. The ovigerous female from station 274 of USS "Blake" ( Barbados), was selected as the lectotype by Melo­Filho & Melo (1992a). According to Chace (1942), M. paynei Boone is synonymous with this species.
