Type species. Carnarvonis katjae sp. nov.
Diagnosis. Body laterally compressed, not vermiform. Eyes absent.Antenna 1 longer than antenna 2, accessory flagellum of two articles. Antenna 2 flagellum shorter than peduncle, calceoli absent. Mandibular palp of 3 articles, right and left palp with slightly different setation. Labium (lower lip) lacking inner lobes. Coxae 1–4 distinctly longer than coxae 5–7; coxa 1 distinctly shorter than coxae 2–3; coxa 4 with small but distinct excavated corner on the posterior margin. Gnathopods 1–2 not distinctly large (propodus smaller than head length), not sexually dimorphic; gnathopod 2 propodus slightly longer than in gnathopod 1; gnathopods 1–2 propodus lateral face with distinct excavation above and parallel to palm margin, palm margins smooth, without robust setae along palm margin, with 1 mesial (inner) and 1–2 lateral (outer) robust setae either side of palm corner (where dactyl fits to the propodus). Pereopod 6 and 7 of similar lengths, bases broad (less than 1.5 times as long as wide). Coxal gills on pereopods 2–6, sternal gills on thoracic segments 2–6, slender, not greater than ½ length of coxal gills. Uropod 3 outer ramus of 1 article, inner ramus absent. Telson shallowly cleft, with apical setae.
Etymology. Named for the Carnarvon Station Reserve where the holotype material was collected. Gender: feminine.
Remarks. Carnarvonis gen. nov. and Warregoensis gen. nov. share some distinct traits from Chillagoe . They do not have a basofacial seta on uropod 1 and the uropod 3 outer ramus is composed of a single article (vs. 1 basofacial seta present on uropod 1 and uropod 3 outer ramus of two articles in Chillagoe ). Carnarvonis gen. nov. can be clearly identified from the smooth palm margin of gnathopods 1–2, a shallowly cleft telson and pereopods 5–7 bases broad (less than 1.5 times as long as wide).
