Dorsal setae smooth, except Z5, which are serrate.

Peritreme ­ Reaching level of z2.

Venter ­ All ventral shields smooth. Distances between ST1­ST3 56 (50­66) [56], ST2­ ST2 66 (61­72) [64] and ST5­ST5 72 (62­82) [68]. With 1 pair of metapodal shields. Ventrianal shield 100 (88­123) [102]long, 57 (46­72) [62] wide at ZV2 level and 65 (58­ 77) [63] wide at anus level.

Spermatheca ­ Calyx flared, 31(24­40) long; atrium indistinct; minor duct prominent.

Legs ­ Macrosetae blunt to knobbed: SgeII 20 (16­26) [20], SgeIII 26 (24­30) [24], StiIII 20 (13­24) [20], SgeIV 39 (30­46) [39], StiIV 32 (22­37) [31], StIV 41 (29­56) [52].

REMARKS: The fact that this was one of the most common species found in this study and that no male was ever found indicates that it is a thelytokous species.
