Nagada Lowry & Stoddart, 1995 View in CoL

( Fig. 26 View FIGURE 26 )

Nagada Lowry & Stoddart, 1995b: 146 View in CoL .— Lowry & Stoddart, 2003: 283.

Type species. Nagada uwedoae Lowry & Stoddart, 1995 View in CoL , by original designation.

Included species. Nagada View in CoL includes three species: N. garagassi Lowry & Stoddart, 1995b View in CoL ; N. papua Lowry & Stoddart, 1995b View in CoL ; Nagada uwedoae Lowry & Stoddart, 1995b View in CoL .

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 .
