Distribution map of Metridia boecki by geographical zones
|
| | | | | | | Loc: | | | South Africa (E), SW Indian, Laccadive Is., Indonesia-Malaysia, San Diego, Pacif. (Costa Rica: Punta Arenas), off Peru | | | | N: | 9 | | | | Lg.: | | | (46) F: 2,65; (67) M: 2,01-1,95; (142) F: 2,5; {F: 2,50-2,65; M: 1,95-2,01}
The mean female size is 2.575 mm (n = 2), and the mean male size is 1.980 mm (n = 2). The size ratio (male : female) is about 0.77. | | | | Rem.: | Grice & Hulsemann (1967, p.28) ascribe the form (M) without certitude to M. boecki, differ slightly from M. discreta.
The females resemble Metridia lucens females. | | | Last update : 07/12/2020 | |
