Dorsal surface

The podosomal shield is medium in size with the shape of an inverted letter "T"; the front part is slightly sclerotized, carries on its surface 4 pairs of long setae (j2,3, z2,3); the back part, strongly sclerotized and carries 2 or 3 long setae (j5, z5), noticeably removed from the edge of the shield. Four pairs of mesolateral setae are located lateral to the podosomal shield (r2-4, s4), two pairs of mesolateral setae are behind the shield, near stigma (s5,6). On the opistosomal part of the idiosome there are 14 pairs of setae (J1,5,6,7,8, Z1-3, R1-5). Stigmas with peritrems are located at the back of coke III.

Ventral surface

There is no sternal shield. There are 3 pairs of sternal setae of similar length (St1-3). Lateral to the St1-2 setae are two pairs of pores. The genital shield is long and very narrow. Lateral to the genital shield there is a pair of genital setae (he4) and a pair of pores. On the opistosomal side of the idiosome there are 14 pairs of long setae (Jv1-7, Zv2,6,7, UR5-7). The anal shield is narrow, with cribrum. The anus is located in the center of the anal shield. Preanal and postanal setae long.

Gnatosome

Fingers slightly shorter than gnatosome base, with thin setae. The deuterosternal denticles (Dd) are large, along the entire medial line of the gnatosome, symmetrically arranged in ten rows; starting from the fourth front row, three, four cloves in a row are clearly visible. Gnatosomal formula 2-4-2. Hypostomal setae (hyp) long. Tritosternum (Trs) with a short triangular base and long laciae.

Leg

Coke: 2-2-2-1-1, trochanter: 4-4-4-4, thigh: 10-9-6-5, knee: 10-8-7-7, lower leg: 9-9-9-9, foot: 31-15-16-16.
