Trichobothria Fp are very long, thin and usually well extending beyond posterior margin of plate, Oi very short and thin. Lateral eye lenses on each side separate and located in soft integument. Coxal plates I to III small, separate, and with three pairs of coxal setae (C3 on coxal plate II absent). Chelicerae separate and very stout, chela short and edentate. Pedipalp five-segmented, P–4 with large dorsodistal bifurcate claw. Legs I to III six-segmented and each with three claws, the lateral ones extremely thin. Number of setae on legs I–III (specialized setae given in parentheses): I–Leg-1–6: 1, 2, 5, 6 (s, e), 13 (2 s, e), 22 (s, e, ac); II–Leg-1–6: 1, 2, 5, 6 (s, e), 12 (2 s), 22 (s, e, ac); III–Leg-1–6: 1, 2, 5, 5(s), 11 (s), 20.
