Type material. Holotype: ♂ from Sítio do Alemão (03°50’50.7”S, 40°53’18.5”W), Chapada do Ibiapaba, Ubajara , Ceará, Brazil , 21.X.2012, leg. A.M. DeSouza et al. ( UFMG 14852 View Materials ) GoogleMaps   . Paratype: BRAZIL: Ceará: Ubajara, Parque Nacional de Ubajara, Trilha da Samambaia (03°50’19.4”S, 40°53’58.6”W), 25.X.2011, leg. L.S.

Etymology. The specific name is a noun in apposition after the type locality.

Diagnosis. Males of Tupirinna ibiapaba   sp. nov. differ from those of other species with the embolar process positioned dorsally in relation to the embolus and the dorsal lobe of RTA represented by a small retro-apical hump ( T. trilineata   and T. palmares   sp. nov.) by the combined presence of a long, filiform embolus, VTA as long as wide, and by the absence of a tegular retroapical projection ( Fig. 14A, B View FIGURE 14 ). Females resemble those of T. trilineata   by the incomplete, recurved margins of the copulatory opening, differing by the sub-triangular copulatory pouch ( Fig. 14C, D View FIGURE 14 ).

Description. Male holotype (UFMG 14852). Carapace orange, with brown stripe extending over ocular area, and brown stripes laterally. Chelicerae orange. Labium brown, with top edge pale brown. Endites orange. Sternum yellow, with borders and anterior lateral excavations brown. Legs yellow. Abdomen dorsum yellow, with one pair of black longitudinal spots in cardiac area; in median region, two pairs of black spots on each side; subsequently one black subrectangular spot, yellow in the middle portion. Contour of spinnerets black; venter yellow ( Fig. 5C View FIGURE 5 ). Total length 4.91. Carapace length 2.74, width 2.28, height 0.66. Clypeus height 0.13.

Palp: tibia shorter than half cymbial length; ventral lobe of retrolateral tibial apophysis short, without apical spur; dorsal lobe represented by small hump; ventral tibial apophysis curved apically, with small retrolateral process; embolus long, embolar basal process present; tegular process absent ( Fig. 14A, B View FIGURE 14 ).

Female paratype (CHNUFPI 2402). Carapace orange, with brown stripe extending over ocular area, and black stripes laterally. Chelicerae orange. Labium brown. Endites yellow.
