Movable and fixed cheliceral digits with four and nine teeth, respectively. Form of cheliceral arthrodial process and position of setae h 1, h 2 and h 3 unknown. Epistome with an anteromedian extension wider at the base, entirely smooth or with distal half slightly serrate, and flanked by a pair of smooth or slightly serrate anterolateral extensions shorter than the anteromedian extension. Idiosoma elongate, 340–360 µ m long and 150–160 µm wide at widest level. Ratios of width of podonotal and opisthonotal shields to maximum width of idiosoma 1 and 0.8, respectively. Dorsal idiosomal setae smooth. Podonotal shield 1.2 times longer than wide; smooth; with punctate band along posterior margin; with 23 pairs of setae, including four pairs (j 1, j 2, z 1 and s 1) near anterior margin; with transverse line between setae j 4 and j 5 and with four scleronoduli between setae j 5 and j 6. Soft integument along lateral margins of podonotal shield without setae. Opisthonotal shield 1.7 times longer than wide; smooth; without punctate band along anterior margin; with 16 pairs of setae. Soft integument along lateral margins of opisthonotal shield with three pairs of setae. Peritreme extending anteriorly to level of anterior margin of coxa III. Peritrematic shield indistinct. With two pairs of presternal platelets. Sternal shield longer than wide, with anterior margin indistinct and posterior margin convex. Genital shield longer than posterior width; posterior margin convex. Opisthogaster without platelets between genital and ventrianal shields. Ventrianal shield longer than wide, smooth, with five pairs of preanal setae; anterior margin slightly convex. Soft integument around ventrianal shield with two pairs of setae. With a pair of elongate metapodal platelets. Pretarsus I absent. Seta pl 4 of tarsus IV absent.
