Distribution map of Parvocalanus dubia by geographical zones
|
| | | | | | | | | | | | | Loc: | | | off Cape Verde Is. (in Chasavar-Archad & Razouls, 1982), E Medit. (N Lebanon Basin), Indian (off S Cochin, Rushikulya estuary, Bay of Bengal), Burma, Mooth of Rangoon River), Australia (North West Cape), Viet-Nam (Nha-Trang), off E New Guinea. | | | | N: | 9 | | | | Lg.: | | | (81) F: 0,74; {F: 0,74} | | | | Rem.: | For Sewell (1912, p.332) this species differs from P. crassirostris by the absence of spines on the margin of exopod 2 of P2; absence of spines on the posterior aspect of exopodal segments 3 of P3 and P4; serrated saw on P5; shorter terminal segment of A1.
The identified form from off Cape Verde Islands would confirm that this species is only a variety, or an anomaly, of Parvocalanus crassirostris; and also in the Eastern Mediterranean Sea (Levantin Basin) in Uysal & Shmeleva (2012 (p.918: Table I). | | | Last update : 21/08/2018 | |
