- femur II with 3 setae (d, bv", v' present; l' absent)
- genua I-II with 3 setae (d, l', l")
- tarsus I with companion seta longer than solenidion, finely tapered, can appear subequal if fine tip is broken (Fig. 6)
- tarsus II with companion seta slightly longer than or subequal in length to solenidion (Figs. 7, 8)
- dorsal seta on tibiae I-II thick, with spatulate tip, sometimes with a tapered blunt tip (Figs. 6, 7, 9)
