Loc. Two specimens in damp soil, Goodenough Is,, Aug., 1944 (D.C.8.). 
Remarks. In the form and length of the dorsal setae, and the absence of an 
external spine on the palpal tibia this species closely resembles pusilla Herm. from 
Europe. It differs, however, in the dimensions of the front tarsi and metatarsi,
