Cymbasoma frondipes  (Isaac, 1975)   (F)
Syn.: Thaumaleus thomsoni : T. Scott, 1904 (p.248, Descr.F, figs.F);
Thaumaleus frondipes Isacc, 1975 (p.3, 8, figs.F)
Species Cymbasoma frondipes - Plate 1 of morphological figuresIssued from : T. Scott in Ann. Rep. Fish. Bd Scotland, 1904, 22 (Part III), IV. [Pl. XIV, Fig.1]. As Thaumaleus thomsoni.
Female (from off Scarborough, Scotland); 1, habitus (dorsal).

Nota : Cephalothorax about equal to twice the entire length of the remaining segments of the thorax and abdomen combined.


Species Cymbasoma frondipes - Plate 2 of morphological figuresIssued from : T. Scott in Ann. Rep. Fish. Bd Scotland, 1904, 22 (Part III), IV. [Pl. XIV, Figs.2-4]. As Thaumaleus thomsoni.
Female: 2, A1; 3, P5; 4, abdomen and caudal rami.

Nota : A1 shoprt and stout, appear to consist of 4 segments, but the 3rd, which is small, seems to be partly coalescent with the 2nd.
P5 moderately large, foliaceous, and abruptly wider at the distal extremity, the result of a lobe-like process on the inner distal aspect ; each foot carries 3 apical setae, the innermost of which is considerably shorter than the other two.
Abdomen 2-segmented ; 1st segment fully half as long as the last segment of the thorax, and large rand more dilated than the 2nd segment.
Caudal rami short, carry 3 moderately elongated setae.

Rem.: This form is considered as a synonym of Thaumaleus thompsoni Giesbrecht,1892, although Isaac (1975) considers this species valid.
