Genus Norileca Bruce, 1990 View in CoL View at ENA

Norileca Bruce, 1990: 289 View in CoL .— Bruce, Lew Ton & Poore 2002: 181.— Wal, Smit & Hadfield, 2017: 163–175.

Type species. Livoneca indica Milne Edwards, 1840 , by original designation ( Bruce 1990).

Diagnosis. Bruce (1990) and Wal et al. (2017) provided a provisional diagnosis for this genus.

Reamarks. Norileca can be identified by the body weakly vaulted dorsally, twisted to one side; cephalon posterior margin weakly or not trilobed; coxae narrow, those of pereonites 3–7 shorter than respective segment; pleonites 1 and 2 without ventrolateral processes, pleonites 1–5 becoming progressively narrower; uropods not extending beyond posterior of pleote1son; uropods not extending beyond posterior margin of pleotelson.

Bruce (1990) and Wal et al. (2017) discussed this genus is most similar to Livoneca with which it shares a similar pereopod, cephalon and pleon morphology, all of which are robust and lacking an expanded carina on the base of the pereopods; the cephalon posterior margin is trilobed; and the lateral margin of pleonites 1–3 are never bilobed. Other major differences to Livoneca are the expanded mandible palp article, lack of folds on endopods of pleopods 3 and 4 and lack of branchiated pleopod peduncles ( Bruce 1990). Norileca can be distinguished from other cymothoid genera by pleonite 1 being the widest of the pleonites, as well as its weakly twisted body shape ( Hadfield 2012).
