discussion
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. Apseudes holthuisi B ă cescu, 1961
discussion
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.
