Key characters

  • setae c1, d1, e1 spatulate (Fig. 1)
  • seta h1 subequal in length to h2 (Fig. 2)
  • seta h2 weakly spatulate (can appear blunt)
  • seta f2 longer than f3 (f2 inserted posterolaterally) (Figs. 2, 3)
  • coxae III-IV with one seta (3b, 4b) (Fig. 4)
  • femur II with 4 setae (d, l', bv", v')
  • genua I-II with 3 setae (d, l', l")
  • tarsus I with companion seta obviously longer than solenidion (Fig. 5)
  • tarsus II with companion seta obviously shorter than solenidion (Fig. 6)
  • dorsal setae on tibiae I-II setiform, tapered
  • palp tibiotarsus with one solenidion and one tapered, setiform eupathidium with forked tip distally (Fig. 7) (can be difficult to see), and one seta dorsally
