- setae c1, d1, e1 minute, blunt (Figs. 1-4)
- seta h1 obviously longer than h2 (Figs. 5, 6)
- seta h2 short, setiform, tapered or with blunt tip (Figs. 5, 6)
- seta f2 obviously shorter than f3 (Figs. 5, 6)
- coxae III-IV nude
- femur II with 4 setae (d, l', bv", v')
- genua I-II with 2 setae (l', l" present; d absent)
- tarsus I with companion seta longer than solenidion, finely tapered (Fig. 7); companion seta often broken and appears subequal to or shorter than solenidion (Figs. 8, 9)
- tarsus II with companion seta slightly longer than, or subequal to solenidion (Fig. 10)
- dorsal seta on tibiae I-II setiform with tapered tip (can be finely tapered)
- palp tibiotarsus with one solenidion and one blunt eupathidium distally (Fig. 11), and one seta dorsally
- setae ps1 and ps2 inserted adjacent to each other (Fig. 12)
- male with moderately long ps1 setae, 13-15 microns (Fig. 13)
