Type species. Nagada uwedoae Lowry & Stoddart, 1995 , by original designation. Included species. Nagada includes three species: N. garagassi Lowry & Stoddart, 1995b ; N. papua Lowry & Stoddart, 1995b ; Nagada uwedoae Lowry & Stoddart, 1995b . Diagnostic description. Antenna 1 peduncle without posterodistal lobe or spine; accessory flagellum with an elongate article 1 (at least twice as long as article 2) partially covering callynophore. Antenna 2 without brush setae. Mandible incisors large, convex; left lacinia mobilis a cuspidate peg; molar a setose tongue . Maxilla 1 outer plate setal-teeth a well developed 7/4 crown. Maxilla 2, inner plate significantly shorter than outer. Gnathopod 1 simple ; coxa large, about as large as coxa 2 with a straight anterior margin; ischium long (length 2 × to 4 × breadth); carpus long (length 2 to 4 × breadth), dactylus with or without complex spines on posterior margin. Uropod 2 inner ramus constricted. Uropod 3 outer ramus article 2 long. Telson entire . Remarks. Based on simple first gnathopod with long ischium and an entire telson Nagada is similar to Eclecticus . Both genera have the mandibular palp attached midway, both have a well developed 7/4 crown on the outer plate of maxilla 1, and both have a long ischium on the first gnathopod. They differ mainly in the dactylus of gnathopod 1 which has an explosion of complex setae on the anterior margin in Eclecticus .
