Apseudes tenuimanus Sars, 1882 A. tenuimanus , Sars, 1886, 282– 286, Pl. 3. Material examined : 1 juvenile (NHM. 2008.3798), station RFI 2, 31º 53.328 ’N 034º 32.853 ’E, 58 m depth; fine mud, 25 May 2006. Remarks. Recorded before off Israel (Haifa Bay) at 36 m depth by Băcescu (1961) and off Italy by Sars (1882; 1886). Not known outside the Mediterranean. This species is distinguishable from others in this region by its blunt, triangular rostrum, and reduced spination on pereopod 1 (only one ventral spine on the carpus); a small lateral spinose apophysis is present on the cephalothorax anterior to the branchial chamber.

Remarks. This exclusively Mediterranean species was distinguished from the north-east Atlantic species Apseudes talpa by Băcescu (1961), the type locality being “off Haifa”. Interpretation of the literature by Sieg (1983) gives a depth range from 2 to 300 m, but this is likely to be an overestimate. The carpus of pereopod 1 has two ventral spines; there is no branchial apophysis, but small anterolateral spinose apophyses are present on pereonites 2 to 6, those on the anterior pereonites being hook-like. : Published as part of Bamber, Roger N, Bird, Graham, Błażewicz-Paszkowycz, Magdalena & Galil, Bella, 2009, Tanaidaceans (Crustacea: Malacostraca: Peracarida) from soft-sediment habitats off Israel, Eastern Mediterranean, pp. 1-44 in Zootaxa 2109 on pages 5-6, DOI: 10.5281/zenodo.187828 : {"references": ["Sars, G.
