Description
Platysympus typicus (Sars, 1870)
Platyaspis typicus Sars, 1870: 159; 1900: 27, pl. 19–20.— Corey, 1981: 1732.— Jones, 1985: 431.
Platysmpus typicus. — Stebbing, 1912: 144; 1913: 61.— Corbera & Galil, 2001: 137–140, figs 2–3.
Type material. Syntypes: deposition unknown. Lofoten, Norway. Not seen.
Other material. Two ovigerous females, 16 subadult females, 3 adult males, 13 other, MNHN Cu 224, 240– 360 m.
Diagnosis. Carapace with branchial swellings, with weak ridges, in lateral view without dorsal humps. Telson 2.5 pleonite 6, 0.8 uropod peduncles, without lateral setae. Adult male carapace streamlined, generally with less serration than in female; antennule with group of aesthetascs on first article of main flagellum; antennal flagellum short, extending to end of pereon.
Depth. 220–2857 m.
Distribution. North Atlantic, Norway to Mediterranean Sea.
Remarks. There has been discussion about the lack of distinction between Platysympus typicus and P. tricarinatus, due to the varying presence of “dorsal keels” in P. typicus, as discussed in Corbera & Galil (2001, and references within). However, Hansen (1920) illustrated the telson of P. tricarinatus with lateral setae, and there has been no reference to P. typicus having lateral setae on the telson. The edges of the telson may be serrate, and the strength of the serrations may vary in P. typicus (Corbera & Galil 2001), but there are no setae present.
