Tr I–IV with 1-1-1-1 setae; Bf I–IV with 2-2-2-2 setae; Tf I–IV with 5-5-2-2 setae; Gn I–IV with 4-4-3-3 setae; Tb I–IV with 5-5-5-5 setae; Ta I–IV with 3-3-3-3 dorsal setae. Idiosoma length 157–165 in female (holotype 160). Lc II–IV with unidentate accessory process and comb. Idiosoma width 97 in holotype female. Gnathosoma length 72 in holotype female.
