Pseudocyclopia giesbrechti  Wolfenden, 1902   (F,M)
Ref.:
Wolfenden, 1902 (p.370, Descr.F, figs.F); T. Scott, 1905 d (p.141, Descr.M, figs.M, Rem.); van Breemen, 1908 a (p.91, 224, figs.F,M); Sars, 1919 (1921) (p.7, figs.F,M); Rose, 1933 a (p.169, figs.F,M); Jaume & al., 1999 (p.405); Boxshall & Halsey, 2004 (p.171, figs.F,M)
Species Pseudocyclopia giesbrechti - Plate 1 of morphological figuresissued from : T. Scott in Rep. Fishery Bd Scotl., 1905,23 (3). [Pl. X, Figs.1-7, 9].
Male (from Firth of Forth, Scotland): 1, habitus (lateral); 2, A1; 3, A2; 4-7, P1 to P4, respectively; 9, urosome (dorsal).
Nota: Cephalothorax composed of 4 segments, but the 5th is so small as to be almost entirely obscured by the 4th. A1 17-segmented. A2 exopod scarcely so long as the endopod composed of 5 segments (Wolfenden describes A2 as 1-segmented but had probably become accidentally lost).


Species Pseudocyclopia giesbrechti - Plate 2 of morphological figuresissued from : T. Scott in Rep. Fishery Bd Scotl., 1905,23 (3). [Pl. X, Fig.8]
Male: P5.
Nota: P5 asymmetrical, left leg is long and slender (extrmity apparently damaged), a dense fringe of small delicate hairs extends along part of the proximal half of the inner margin of the terminal segment, and terminates distally at a small hook-like process; the right leg is dilated at the proximal end of the 2nd segment, the 3rd segment is narrow, and terminates interiorly in 1 or 2 finger-like processes; the terminal segment very slender, and tapers gradually to a pointed apex, furnished with a a small process exteriorly near the proximal end.

Female: 4, P3 (ventral view); 7, P5 ( (posterior); 8, A1; 9, A2; 10, Md; 11, Mx1; 12, Mx2; 13, Mxp.

Distribution map of Pseudocyclopia giesbrechti by geographical zones

After Sars (1919, p.8) the figure of right P5 in Scott is described as the left, and vice versa.
