M.S. Wilson (1946, p.5) points to after Sars that the female shows A1 with 23 segments (apparently 5 or 6 aesthetascs); A1 male 16-segmented (10 or 12 aesthetascs based on illustrations); legs 1 to 4 like female; exopod of P5 2-segmented, distal segment somewhat emongated, constricted near the proximal end and bearing a stout, hyaline franged spine at this point; end of segment transversaly truncated and carrying a thin partly ciliated lamella, flanked internally by a long styliform spine and on the outer edge by 2 unequal spines; endopod 3-segmented, 1st segment unarmed, 2nd bearing a long slender spine, 3rd with 5 short spines.
