| Summary: | Dutoitella richarddinglei sp. nov. (Figures 2, 9–14, Table 1) Diagnosis. A Dutoitella species with sub-oval outline, angulate primary reticulation and lack of secondary reticulation. Dorsal margin carries four or five bullae. Anterior marginal rim conspicuous, and numerous blade-like or conical spines on the anterior and posterior margins. Derivation of name. In honor of Richard V. Dingle for his outstanding contributions to ostracodology, micropalaeontology and palaeoenvironmental sciences. Material. (see Tab. 1) Two “live” (=with soft parts) males, seven Subrecent valves. 1) HOLOTYPE— One male (SNB 0293) on two slides: dissected soft parts mounted in Hydromatrix permanent medium on a glass slide (ZMH K- 44858a); 1 right valve and 1 left valve on a micropalaeontological slide, both coated for SEM (ZMH K- 44858b). 2) PARATYPES (type locality)— 1 male (SNB 0294) on two slides: dissected soft parts mounted in Hydromatrix permanent medium on a glass slide (ZMH K- 44859a); 1 right valve and 1 left valve on a micropalaeontological slide, both coated for SEM (ZMH K- 44859b). 1 adult right valve, 1 juvenile right valve (ZMH K- 44860). 3) PARATYPES (other localities)— (A) ANDEEP III, station 80-6: 1 left and 1 right valves on a micropalaeontological slide (ZMH K- 44861). (B) ANDEEP III, station 81-9: 1 left and 2 right valves on a micropalaeontological slide (ZMH K- 44862). Stratigraphic and geographical occurrence. (localities 1 to 3 in Fig. 2 and Tab. 1) Quaternary and living. Scotia and Weddell seas, Atlantic Sector of the Southern Ocean, 2970 to 4384m depth. Type locality. Recent and Subrecent.
