This genus is suggested to include some species of the old 

 world and at least one from the new, Damaeus magnisetosus 

 Ewing. Most of the species have the pseudostigmatic organs 

 very long, the integument of the legs minutely tuberculate, 

 while the tibiae of the first pair of legs each bears above and 

 distally a large tubercle from which a long tactile seta extends.
