Male: 126, habitus (lateral left side); 127, P5 (anterior). Nota: 2nd urosomal segment about 1.5 times as long as 3rd or 4th urosomal segment.
Meso-bathypelagic. ? Cf. Scaphocalanus invalidus. According to Park (1970, p.501), judging from the size of the body and the shape of P1, some of females reported by Tanaka (1961) as S. curtus seem belong to the present species. Vyshkvartzeva (1993, p.13) emphasizes the P1 with an inner basal seta and outer endopodal lobe.
