Distribution map of Pontellopsis strenua by geographical zones
Loc:
off Bermuda (in Deevey & Brooks, 1977, Station ‘’ S’’: 32°10’N, 64°30’W), Sri-Lanka, Indian, G. of Thailand, Indonesia-Malaysia, Philippines, Viet-Nam (Cauda Bay), China Seas (East China Sea, South China Sea), Taiwan (SW), Japan (Honshu), Pacif.

N: 21
Lg.:
(46) F: 2,8; M: 2,35; (276) F: 2,744; (290) M: 2,85; (1023) M: 4,3*; {F: 2,74-2,80; M: 2,35-2,85}
*Nota: The length ot male is abnormally great.
Rem.: mesopelagic. Overall Depth Range in Sargasso Sea: 0-500 m (Deevey & Brooks, 1977, Station "S");
This species is hard to distinguish from P. regalis.
If the identification from the Bermudas is correct, this species could have been isolated at the time of the closure of the Isthmus of Panama.
