Cymbasoma janetae  Mageed, 2010   (F)
Ref.:
Mageed, 2010 (p.515, Descr.F, figs.F)
Espèce Cymbasoma janetae - Planche 1 de figures morphologiquesissued from : A.A.A. Mageed in Crustaceana, 2010, 83 (5). [p.516, Fig.2].
Female (from 34°43'N, 29°10'E): habitus (lateral).
Nota: Cephalothorax representing 71 % of total body length; cephalothorax without any obvious cuticular surface ornamentation.
Oral papilla located at 17 % along ventral surface of cephalothorax from anterior end.
Proeminent processes between oral papilla and bases of A1.
Eye present, well-developed.
Forhead smooth. Urosome 3-segmented (pedigerous somite 5, genital-double-somite and 1 free somite).
P5 with inner, finger-like endopodal lobe, parallel to exopodal lobe. Exopodal lobe twice as long as wide, with 3 setae, innermost about half the length of the other two.
Genital double-somite slightly shorter than one-third of total length of urosome (32.4 %), ventral portion swollen posteriorly, bearing 2 long ovigerous spines, 1.1 times total body length, fused proximally from base to beyond caudal rami
Caudal rami 1.37 times as long as wide, moderately divergent, bearing 3 terminal setae


Espèce Cymbasoma janetae - Planche 2 de figures morphologiquesissued from : A.A.A. Mageed in Crustaceana, 2010, 83 (5). [p.519, Fig.4].
Female: Left A1 (dorsal aspect).
Designation of armature elements follows Grygier & Ohtsuka (1995).
Nota: A1 4-segmented, about 13.5 % of total body length and 1.9 times as long as cephalothorax. Element 1 is present on the 1st segment; elements 2d1, 2d2, 2v1, 2v2, 2v3 and IId on the 2nd segment; the 3rd segment has elements 3, IIId and IIIv; 4th segment has normally developed elements 4v1, 4d1,2 and 4v2-3, as well as setae IVd, Ivv, Vd and Vm and also element 5. The subterminal elements b1-6 are present. The aesthetasc 4aes is well developed on the ventral surface, and terminal elements 6aes and 6 (2) are present. Element 6 (1) was not observed (may be broken).

Espèce Cymbasoma janetae - Planche 4 de figures morphologiquesissued from : A.A.A. Mageed in Crustaceana, 2010, 83 (5). [p.517].
Female: Armature of swimming legs P1 to P4 (spines in Roman and setae in Arabic numerals).


Espèce Cymbasoma janetae - Planche 5 de figures morphologiquesissued from : A.A.A. Mageed in Crustaceana, 2010, 83 (5). [p.520, Pl. 2].
Female: A, genital double-somite; B, caudal rami and ovigerous spine base.
Nota: Eight shallow, transverse cuticular wrinkles present on lateral margin and dorsal surface of genital double-somite

N: 1
Lg.:
(1082)* F: 1,78 * measured in dorsal view (caudal rami excluded)
Rem.: For Mageed (2010, p.520) the species is most similar to C. longispinosum (Bourne, 1890), also similar to C. morii Sekiguchi, 1982, C. chelemense Suarez-Morales & Escamilla, 1997, and C. californiense Suarez-Morales & Palomares-Garcià, 1999 mainly in the presence of the dorsal cuticular wrinkles on the genital double-somite in addition to the other characters that distinguish it from C. longispinosum.
This form is assignable to Cymbasima longispinosum species-group.
