The mean female size is 1.088 mm (n = 8; SD = 0.1196) and the mean male size is 0.785 mm (n = 6; SD = 0.1394). The size ratio (male : female) is establish on one sample with males and females: 0.83. | | | Rem.: | For Frost & Fleminger (1968, p.53) the ventral protuberance of the genital segment anterior to the genital pores distinguishes females of C. farrani from all other Clausocalanus species except C. jobei; the latter differs from farrani only in the shape, curvature, and length of the rostrum. Females of C. farrani differ from minor in the form of the P5, and from paululus in body length, in the form and spacing of basipodite 2 spiniform processes 2 and 3 of P3. The C. farrani male differs from jobei in the armature of the distal segment of left P5 and the ratio of left 2nd segment of P5 length to urosomal segment 2 width. The very similar males of C. farrani and minor are distinguished by the length ratio of A1 fused segments 20-21 to segment 22 and usually by the segmentation and appearance of the right P5, particularly the size of the distal segment. Males of C. farrani and paululus are easily separated by body length, the urosomal segment 2/3rd segment of P5 and 3rd segment of P5/ 2nd segment of P5 length ratios, and the form of basipodite 2 spiniform processes 2 and 3 of P3. The authors have not located designated types or original material for C. farrani, but Sewell(s (1929) description and illustration are sufficient to leave little doubt as to the identity of his material. After Cornils & al (2007, p.63) the percentage of females infected by Blastodinium sp. was 1.9 %, ±0.5); with impact on P5 (abnormal), the left ramus has developed one or two additional segments. The Atlantic locality records need a confirmation although Calef & Grice (1967) have reported the species off Guyane. | | | Last update : 25/10/2022 | |
