Summary: | Renella gen. nov. Type species. Drummondia sculptidentata Ren in Ren & Huang, 1991. Etymology. The generic name is based on the name of the author of the type species, Dr Xiang Ren. Diagnostic description. Body shape slender. Head lateral cephalic lobe large, broadly rounded . Antenna 1 peduncular article 1 with posterodistal spine; accessory flagellum article 1 short; flagellum with callynophore in female. Mandible with accessory setal row present on both sides; left lamina dentata absent; palp attached distally palp article 2 broad, article 3 with anterior margin convex, not tapered distally. Maxilla 1 outer plate setalteeth with medial cusps, STA–STD present; palp vestigial, 2-articulate . Maxilliped inner plate small; outer plate large; palp 4-articulate, article 4 large . Gnathopod 1 ischium smaller than propodus; corner of palm with complex robust seta. Gnathopod 2 palm transverse. Epimeron 3 posteroventral corner broadly rounded. Uropod 3 biramous. Species composition. Renella sculptidentata (Ren in Ren & Huang 1991). Remarks. Renella has a vestigial maxilla 1 palp, similar to Coriolisa , Prachynella and Sheardella . It differs from Coriolisa and Prachynella in having a well-developed fourth article on the maxillipedal palp. Renella and Sheardella have a number of significant differences, but can be easily distinguished by uropod 3 which is biramous in Renella and uniramous in Sheardella . Renella is currently a monotypic genus confined to Antarctic waters. : Published as part of Lowry, J. K. & Stoddart, H. E., 2012, The Pachynidae fam. nov.
