( Fig. 6 )

Diagnosis. This new species is characterized by having z2 shorter than the distance between its base and the base of z4; z4 longer than the distance between its base and the base of s4; s4 as long as Z4, and both longer than Z5; sternal and genital shields smooth; Jv5 smooth; and by lacking S4.

Female. (1 specimen measured).

Dorsum. Dorsal shield smooth, 389 long and 233 wide. Setae j1 21, j3 35, j4 2, j5 2, j6 2, J5 8, z2 13, z4 74, z5 2, Z1 10, Z4 86, Z5 64, s4 88, S2 11, S5 11, r3 14, R1 11. Setae smooth, except Z4 and Z5 which are serrate; S4 absent .

Venter. Sternal shield mostly smooth, with some rare lateral striae; posterior margin concave; distances between St1-St3 53, St2-St2 80. Genital shield smooth, with 3 pairs of distinct, elongate muscle scars; distance between St5-St5 106. Ventrianal shield pentagonal, with transverse striae and 2 pairs of distinct, roundish muscle scars, anterior margin slightly concave, 115 long, 110 wide at level of Zv2 and 106 wide at level of anus, preanal pores small and posteromesad to Jv2. Two pairs of metapodal shields. Ventral setae smooth.

Chelicera. Movable digit 33 long, apparently with 1 tooth; fixed digit 29 long, apparently with 5 teeth and a pilus dentilis.

Spermatheca. Calyx cup-shaped 10 long; atrium distinct.

Legs. Sharp-tipped macrosetae; Sge III 26, Sge IV 53, Sti IV 40, St IV 72. Chaetotaxy: genu II: 2–2/1,2/0– 1: genu III: 1–2/1,2/0–1.

Male. Unknown.

Locality and type material. Holotype female from Citrus sp. , Luwero, Kyankonwa, Uganda, 05-X-1990, J.S. Yaninek, deposited at ESALQ-USP.

Etymology. The epithet atrichos refers to the absence of seta S4 on the dorsal shield of the type of this new species.

Remarks. The characters of this species fit those of the genus Proprioseiopsis , except the absence of S4 that separate this species from the other Proprioseiopsis species.
