Species Augaptilus anceps - Plate 1 of morphological figuresissued from : O. Tanaka in Publs Seto Mar. Biol. Lab., 1964, XII (1). [p.76, Fig.211].
Female: a, habitus (dorsal); b, forehead (left lateral side); c, last thoracic segment and urosome (left lateral side); d, rostrum (frontal view); e, A2; f, Md; g, Mx1; h, Mxp; i, P1; j, P5.
Nota: The urosome segments and furca are in the proportional lengths as 47:12:11:30 = 100.

Male: k, P5. Nota: The urosome segments and furca are in the proportional lengths as 20:17:15:13:12:23 = 100. The furcal rami 4 times as long as wide. Right A1 exceeds the end of the furca by terminal 1 or 2 segments. Grasping of A1 on the left side. A2: endopod and exopod of about equal lengths.

Distribution map of Augaptilus anceps by geographical zones
S Brazil, Canary Is., off Morocco-Mauritania, Azores, off Bermuda: Station ‘’ S’’ (32°10’N, 64°30’W), Sargasso Sea, off NW Ireland, S Strait of Davis, W Medit. (Ligurian Sea, Tyrrhenina Sea), Indian (Arabian Sea), China Seas (South China Sea), Philippines, Pacif. (tropical), ? California, SW Galapagos, NE Easter Is., N Chile
N: 14
(1) F: 3,6; (24) F: 3,75; (199) F: 3,57; {F: 3,57-3,75}
Rem.: meso-bathypelagic. Known to occur above 600 m depth, probably also deeper (Matthews, 1972). Overall Depth Range in Sargasso Sea: 0-2000 m (Deevey & Brooks, 1977, Station "S");
Fleminger (1967 a) suggests, with doubt, that this species would be synonym to Augaptilus lamellifer.
For Itoh (1970 a, fig.2, from co-ordonates) the Itoh's index value from mandibular gnathobase = 1265.
