Distribution map of Pontoptilus robustus by geographical zones
Loc:
Canary Is., off Bermuda: Station ‘’ S’’ (32°10’N, 64°30’W), W Indian
N: 3
Lg.:
(67) F: 8,51; (1) M: 6,8; {F: 8,51; M: 6,80}
Rem.: Depth: ? (1): vertic. 0-3000 m; Grice & Hulsemann, 1967: 350-940 m; Overall Depth Range in Sargasso Sea: 500-1000 m (Deevey & Brooks, 1977, Station "S");
For Grice & Hulsemann (1967) this species closely resembles P. muticus. Distinguished by its larger size, long A1, and protuding 5th thoracic segment. The male was described from NE Atlantic by Sars (1905, 1925) and the female from NW Indian Ocean.
