Prodorsum elongate with rostrum gradually or abruptly attenuated; rostral setae curved gently; without true lamellae; bothridium position only slightly forward of dorsosejugal furrow. Subcapitulum anarthric; rutella forming tube; chelicerae attenuate-edentate. Palpgenu separate from femur, with one seta; palptarsus with eight setae; distal eupathids on palptarsus fused basally, appearing like forked seta. Notogaster without octotaxic system.
