Female with 51–74 Pgs and 8 Sgs. Tr I–IV with 1-1-1-1 setae; Bf I–IV with 3-3-3-3 setae; Tf I–IV with 7-7-5-5 setae; Gn I–IV with 7-6-5-5 setae, 2-0-0-0 Bp setae; Tb I–IV with 9-7-7-7 setae, 6-3-(2,3)- 2 Bp setae; Ta I–IV with 3-3-4-3 dorsal setae, 1-1-2-1 Bp setae. Lc I with unidentate accessory process. Idiosoma length 340–447 in female, 310–366 in DN, 240–253 in PN. Idiosoma width 245–312 in female.
