 Issued from : O. Tanaka in Spec. Publs. Seto mar. biol. Lab., 10, 1960 [Pl. XXXVI, 6-10]. Female (from 27°37'S, 47°06'E): 6, habitus (dorsal); 7, abdomen (lateral); 8, A2. Nota : Cephalothorax and abdomen in the proportional lengths 64 to 36. Abdominal segments and caudal rami in the proportional lengths 47 : 23 : 30 = 100. Genital segment elongate ovate, 1.5 times as long as broad, and 1.5 times as long as high. Anal segment wider at the proximal than at the distal end, and 2 times as long as it is broad at the posterior border (18 : 9). Caudal rami about 7 times as long as broad (49 : 7). The present female specimen differs from C. giesbrechti described by M. Dahl in the proportional lengths of the abdominal segments and caudal rami (46 : 26 : 28) and in the more robust genital segment. Male (from 35°09'S, 20°13'E): 9, last thoracic segments and abdomen (dorsal); 10, same (lateral). Nota : Cephalothorax and abdomen in the proportional lengths 60 to 40. Abdominal segments and caudal rami in the proportional lengths 40 : 27 : 33 = 100. Genital segment elongate ovate, about 2 times as long as broad; ventral surface with a median hook; cylindrical part 1/1.6 the length of the posterior border of the segment. Anal segment with paralell lateral margins, 2.5 times as long as it is broad at the anterior border (19 : 7.5). Caudal rami 10 times as long as broad (25 : 2.5). Remarks: the male closely resembles C. agilis; the shape of the 4th thoracic segment which is more produced is the present specimen, the slender genital segment with a small ventral hook, and the large cylindrical part are the characters which distinguish the specimen from the male of C. agilis

It is probable that most of the authors having cited C. venustus Dana (synonym of C. crassiusculus) have referred to the form of Giesbrecht (1892) which is a synonym of C. giesbrechti.
After Björnberg (1963, P.82) this species is uually present in Brazilian waters and may occur in dominant or subdominant numbers in shelf and coastal waters.
For Fuentes-Reinés & E. Suarez-Morales (2017, p.519 ), this Colombian form can be easily distinguished from its congeners by: 1- the presence of small medium-sized hook on the anterior surface of genital somite; 2- dorsal margin of genital somite straight; 3- anal somite as long as caudal rami; 4- P4 with 2 unequally long basipodal setae.
For Boxshall & Halsey (2004, p.491) the subgenus (Dahl, 1912) is considered as full generic status pending phylogenetic revision of the whole family at the generic level | | | Last update : 04/12/2020 | |
