Male (from Suruga Bay, Japan, from haul 0-1000 m): a, habitus (dorsal); b, forehead (lateral); c, last thoracic segment with P5 and urosome (lateral left side); d, rostrum (anterior aspect); e, Mx2; f, Mxp; g, P1; h, P2; i, endopod of P3; j, P4; k, distal joint of left P5. Nota: Head and 1st thoracic segment fused, 4th and 5th separate (5th short and truncated in dorsal aspect). Rostrum with a wide base to which 2 slender filaments attached. The abdominal segments and caudal rami in the proportions 16 : 24 : 24 : 20 : 4 : 12 = 100. Caudal rami parallel, longer than wide. Mx1 with 7 long and 2 short setae on the outer lobe; 5 setae on the exopodite; 7 setae on the endopodite; 5 setae on the 2nd basal segment. Mx2 has a denticulated spine on the 5th lobe, the distal segment of endopodite with long vermiform setae. Mxp slender, 1st basal segment with 2 long vermiform filaments and a short bud-like filament.
