Diagnosis. This new species belongs the ariri  species group Chant & McMurtry (2005 b), characterised by having a spermatheca with the calyx cup-shaped, bell-shaped or saccular. The new species differs from T. ariri Gondim & Moraes, 2001  and T. gonzalezi Moraes & Mesa, 1991  by having dorsal shield lightly reticulated and by having j 6 and J 2 short (ratio: 0.23; 0.28 for T. ariri  , respectively and 0.31 and 0.37 for T. gonzalezi  , respectively) and setae Z 4, Z 5, s 4 and Sg IV, Sti IV and St IV longer (ratio: 0.24; 0.65; 0.19 and 0.43; 0.51 and 0.69 for T. ariri  , respectively and 0.25; 0.79; 0.2 and 0.13; 0.28 and 0.56 for T. gonzalezi  , respectively). Calyx of spermatheca is slightly shorter in T. ariri  and distinctly longer in T. gonzalezi  .

Adult Female. Seven females examined. Idiosomal setal pattern ( Chant & Yoshida-Shaul, 1992): 10 A: 10 B/ JV- 3: ZV.
