). Pygidium blunt, nearly hemispherical when viewed dorsally, sparsely setose, with usual four spinnerets (Shear 2008) arranged in a square and set in individual depressions; pygidial process very short, continuing line of pygidium. Males with pregonopodal legs unmodified. Gonopods with coxae globular, fixed, entirely filling gonostome, tightly appressed or fused in midline; prefemora sparsely setose, strongly transverse, articulating with coxae by process fitting into coxal notch. Exomere long, sinuous, arising from distomesal margin of prefemur, endomerite large, distally with three sinuous processes, exceeding other parts of gonopod. Acropodite bulky, solenomere incurved, nearly sessile, opening of seminal canal widened, proximal subtending process widely separated from solenomere, thin, curved, acute; no obvious tibiotarsus.
