Saurotipleona n. gen. Akanthophoreus : Holdich and Bird 1989: in part; Bird 2001: in part, see below Diagnosis Akanthophoreid with pereonites 2–5 as long as broad or slightly longer, lateral margins parallel or slightly produced at pereopod insertion. Pleonite-5 sternite with non-recurved acuminate spur. Pleotelson without lateral spurs. Maxilla setulate. Maxilliped bases with long seta. Cheliped carpus shield large, rounded; fixed finger incisive margin without proximal denticulation; dactylus superior margin smooth. Pereopods 2–3 carpus with three bayonet spines and medial seta. Pereopods 1–3 basis superior margin with PSS; propodus (and some carpus) inferior spinules robust. Pereopod-5 propodus with two superodistal spines. Uropod peduncle simple; exopod two-segmented; endopod slender, about three times length of peduncle. Preparatory male similar to female but pleon slightly larger; antennule fivearticled, stouter than in female. Swimming male not known. Etymology From the Greek saurotos , ‘spiked’, and suffix pleona a similar name to Chauliopleona gender female. Type species Saurotipleona julii sp. nov.; see below. Monotypic. Remarks Two superodistal spines (rather than one) on the propodus of pereopod-5 are plesiomorphic relative to most paratanaoids other than leptocheliids, teleotanaids, pseudozeuxids, heterotanoidids and a few others, such as Tangalooma Bamber, 2008. The presence of this character in an akanthophoreid genus is surprising, although it was apparently observed, but for pereopod-4 and without comment, by Guerrero- Kommritz (2005) for C. hastata . The validity of this is discussed below. : Published as part of Bird, Graham John, 2015, Tanaidacea (Crustacea: Peracarida) of the northeast Atlantic: Chauliopleona Dojiri and Sieg, 1997 and Saurotipleona n. gen. from the ' Atlantic Margin', pp. 1507-1547 in Journal of Natural History 49 (25) on page 1535, DOI: 10.1080/00222933.2015.1005715, http://zenodo.org/record/3999694 : {"references": ["Bird GJ. 2001.
