N: 7
Lg.:
(76) F: 2,04-1,92; (88) F: 1,96-1,72; M: 1,9-1,8; (1000) F: 2,0-1,8; {F: 1,72-2,04; M: 1,80-1,90}
Rem.: meso-bathypelagic. Sargasso Sea: 500-1000 m (Deevey & Brooks, 1977, station "S");
For Park (1970, p.503) the species is related to Scaphocalanus echinatus, but differs from it in having a rudimentary rostrum.
