( Figs 14–18 )

Diagnosis. This new species belongs the ariri species group Chant & McMurtry (2005b), 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 j6 and J2 short (ratio: 0.23; 0.28 for T. ariri , respectively and 0.31 and 0.37 for T. gonzalezi , respectively) and setae Z4, Z5, s4 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): 10A: 10B/ JV-3: ZV.
