Distribution map of Pontella diagonalis by geographical zones

| | | | | |  issued from : P. Pillai in J. mar. biol. Ass. India, 1975, 17 (2). [p.140, Fig.5].
Occurrence of Pontella diagonalis and Pontella securifer collected from 54 stations in the Indian Ocean (See in: Hand Book to the International Zooplankton Collections, volume I, 1969). |
| | | | Loc: | | | South Africa (E), Indian, Laccadive Is., Maldive Is., Bay of Bengal, Andaman Sea, Barren Island, W Malay Peninsula, Java (Jakarta Bay), S Philippines (off Jolo)
Type locality: off Jolo (Philippines). | | | | N: | 16 | | | | Lg.: | | | (137) F: 4; (256) F: 4,8-4,23; M: 4,15-3,94; (900) M: 3,95; (1087) M: 3,9; (1115) F: 4,24-4,94; M: 3,42-3,84; (1126) F: 4,05-4,10; M: 3,90-3,95; {F: 4,00-4,94; M: 3,50-4,15} | | | | Rem.: | epipelagic. Neritic.
For Mulyadi (2000, p.186) the present male specimen agrees with the description of the species by C.B. Wilson (1950) but slight differences were noted in having the proximal outer seta of left caudal ramus with a spur-like spine, and in the form of P5.
For Mulyadi (2011) the species is too diverse to be considered as a member of an Indo-West Pacific Pontella species group. | | | Last update : 08/12/2020 | |
