Comprehensive DescriptionRead full entry
Body smooth, very slender, with lateral processes widely separated. Five pairs of legs. Chelifori well developed, chelate; scape a single joint. Palps five-jointed.
Ovigers ten-jointed, terminating in a pectinate claw, the last four joints with a single row of denticulate spines.
But for the additional pairs of legs it would be quite impossible to separate this genus from Nymphon. Only a single species is for the present recognised, and this appears to have a circumpolar distribution. It has been taken by the Scotch, German, and French Expeditions.” (Hodgson 1907, p. 36)
