 issued from : G.O. Sars in An Account of the Crustacea of Norway, with short descriptions and figures of all the species, 1921a, 8. [Pl. XIII]. Female and Male (from Mediterranean Sea: off Sardinia). Specific characters of Female: Cephalic segment only very slightly dilated in the middle, and considerably exceeding half the length of the body. Eye well developed. A1 4-segmented, short and stout, scarcely exceeding in length1/4 of the cephalic segment ; the last segment about the length of the other 3 combined and gradually narrowed distally, some of its setae ramified. Oral tubule located far in fronf, at only at short distance from the frontal part of the head. Natatory legs with the terminal segment of exopod unusually short, scarcely longer than the middle one. P5 provided at the obtusely truncated extremity with 3 plumose setae, the innermost of which is a little shorter than the other 2 ; inner lobe well defined, triangular, and extending at right angle to the axis of the leg. Abdomen short, not attaining the length of the 2 preceeding segments combined. Genital segment about the size of the last trunkal segmend and, in dorsal view, of a subquadrate form, its ventral face considerably protuberant. Ovigerous spines of an extraordinary length, attaining nearly the double length of the body, and confluent at the base for some distance, distal part much narrower than the proximal one. Caudal rami very small, scarcely longer than they are broad, each only provided with 3 thickish setae of equal length. Specific characters of Male: A1 5-segmented, the 3 middle ones lamellary expanded inside and armed with several short spines in addition to the setae, last segment small, very movably articulated to the preceding one. Natatory legs as in the female ; P5 wholly absent. Genital segment with the copulative appendage divided at the end into 2 short diverging lobes. Caudal rami, each provided with 4 setae of nearly equal length (instead 3 setae for the female).

Taxonomic features and morphometry of females of Cymbasoma longispinosum from Brazil (Leite & al., 2012). Nota: The point of bifurcation of the ovigerous spines at the distal end of the caudal ramus is a character useful to distinguish C. janetae and helps in recognizing the form from Brazil as a different species.

*: caudal rami excluded. | | | | Rem.: | For Suarrez-Morales & Escamilla (1997, p.545 & suiv.) this species is closely related to C. chelemense.
For Suarez-Morales (2011, p.6) and Üstün & al. (2014, p.1402) since Bourne's (1890) original description of C. longispinosum from the English Channel, the species has been recorded in very different geographic areas and latitudes. The improbability of a single monstrilloid species being so widely distributed aside, some of these authors noted morphologic differences with respect to the original description of C. longispinosum, it was later realized that this group of species diverging represent cryptic species, each with a limited geographic distribution. This notion supported the erection of the longispinosum specuies-group. The species-group longispinosum is currently known to contain at least 5 nominal species showing subtle but consistent differences and are distributed in distinct geographical areas. Records of C. longispinosum from India (Martin Thompson, 1973) have been tentatively assigned to C. morii (Grygier, 1994), and the Brazilian specimens reported as C. longispinosum by Leite & al. (2010) probably represent an undescribed species (Suarez-Morales, 2011), as C. longispinosum from Dolgopolskaya (1948) in the Sebastopol Bay shall be assignable to the new species C. sinopense from the Tutkey coasts (Üstün & al., 2014) (See remaks at this species).
After Suarez-Morales & McKInnon (2016, p.88) the previous Australian record of C. longispinosum based on a male specimen (Dakin & Colefax, 1940) could be referable to C. jinigudira Duarez-Morales & McKinnon (2016, p.88). The structure of the genital complex with a medial rounded protuberance fig205Dd) and some additional characters discernible from their illustrations (like the large, wide anal somite and the presence of 4 caudal setae are reminiscent of the male of C. jinigudira. | | | Dernière mise à jour : 28/07/2020 | |
