Diagnosis. One or 2 corneae present. Ds-2 on membranous cuticle. Ds-3 on membranous cuticle. Glps indistinct. Two dorsal seta on PE. 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. Gnathosoma length 217–260 in female, 167–183 in DN, 127 in PN. Ratio of gnathosoma to idiosoma 0.61–0.66 in female, 0.52–0.59 in DN, 0.50 in PN. Ratio of P-2 to P-1 3.10.
