Figure 1. Map of the New Zealand Region (based on CANZ 977) showing boundary of the Exclusive Economic Zone (EEZ) and major place names. I do not consider the number of plumose marginal setae on the pleopods to be significant in differentiating species as it is likely to be size-dependent. For small species (< 0 mm), these differences may be informative, but the extent of the PMS (where the setae start on each margin) is more useful. For all species of a length greater than 5 mm, I have not given counts for the pleopod marginal setae. 0 mEAsurEmENts Whole specimens were measured in lateral view using a micrometer eyepiece, along the axis of the join between the coxae and pereonites. Owing to curvature of many specimens on fixation, dorsal views of specimens are often foreshortened. Many aegids are large, between 3 cm and 6 cm, and may stretch or
end on preservation, rendering apparently precise measurements meaningless. Therefore, lengths for specimens of 20 mm or more are given to the nearest millimetre. Pereopod measurements were made along the axis of the articles for the basis of pereopods –3 and all articles for pereopod 7; for pereopods –3 the ischium, merus and carpus were measured along the inferior margin. tErmINOlOgy Words used in descriptions are shown in Figs 2 and 3. Setae, unless stated otherwise, are simple (following Watling 989).

In Aega this is usually a distinct, acute anteriorly directed process, in Aegiochus it is ventrally and posteriorly bent and in Epulaega gen. nov. it is minute and in dorsal view the head may appear to lack a rostral point. In Rocinela it is a large flat and anteriorly rounded process. In Syscenus and Xenuraega ranges from moderate to small in size. Eyes Range in size from small (infrequent), cirolanid-like proportions as in Aegiochus laevis (Studer, 884) to huge, filling the entire head as in many species illustrated here. It is notable that in many species the eyes are distinctly dorsal, with ommatidia not extending to the ventral surface, and not lateral as in cirolanids and many other Cymothoida. In Aega the surface of the eye is smooth, while in Rocinela the surface of each NMNZ – National Museum of New Zealand, Te Papa Tongarewa, Wellington NTM — Museum and Art Gallery of the Northern Territory, Darwin QFS — Queensland Fisheries Service (now part of DPI, Brisbane) QM — Queensland Museum, Brisbane SAM — South Australian Museum, Adelaide SafM — South African Museum, Cape Town USNM — National Museum of Natural History, Smithsonian Institution, Washington DC ZIAS — Zoological Institute, Academy Sciences, Leningrad ZMA — Zoological Museum, Amsterdam ZMHA — Zoological Museum, Hamburg ZMUC — Zoologisk Museum, University of Copenhagen morphological BL— body length RS—robust seta/setae PMS—plumose marginal setae NAmEs mOrphOlOgy Names for new taxa other than place names and honorifics are derived from Biggs (1990) for Mäori names and Brown ( 956) for traditional classical names. Nomenclature for fishes has been sourced entirely from FishBase (Froese & Pauly 2002–07). ommatidium is distinctly rounded giving a nodular appearance to the eyes. pleon Relatively uniform throughout the family, all genera with five free (not fused) segments. Differences can be observed in the degree of prolongation of pleonite 4 in Aega and the extent to which the posterolateral margins are acute. pleotelson Varies with regard to shape of the margins, setation and ornamentation. Antennule and antenna The antennule differs between genera in the degree of flattening of peduncular articles 1 and 2, the relative extension of the distolateral angle of peduncular article 2, and the relative proportions of peduncular article 3; the length of the flagellum may separate species. The antennal peduncle is relatively uniform, with the first two articles always short; in Aega and related genera, peduncular article 3 is also relatively short; in Rocinela
