Figs 3, 25, 98–106

Type. Male holotype from Senador Porfirio , Pará , Brazil [02°34’S, 51°56’W], 05.III.2001, unknown collector ( MPEG 4994 View Materials ). Paratype: one female from Almeirim, Pará, Brazil [01°02’S, 52°54’W], 03.IV.2005, T GoogleMaps   . Gasnier & M. A. Ribeiro Júnior ( MPEG 6786 View Materials )   .

Etymology. The specific name is an adjective and refers to the dense tuft of long white bristles at the lateral area of the male chelicerae.

Diagnosis. The males of T. hirsutochela   sp. nov. ( Fig. 99) resemble those of T. xingu   sp. nov. in the acute apex of the median apophysis ( Fig. 141), but can be distinguished by the longer and acute tip of the median apophysis ( Figs 98, 99, 101) and by the longer and slender apex of the ental branch of RTA ( Fig. 100). The females resemble those of T. onca   sp. nov. ( Fig. 107) in the projected middle field of epigynum ( Figs 103, 104), but can be distinguished by the coiled shape of the copulatory ducts (CD1 and CD2) ( Fig. 105) and by the triangular shape of the head of the spermathecae ( Figs 105, 106).

Description. Male (Holotype, Senador Porfirio, Pará, Brazil, MPEG 4994). Total length 7.18. Carapace 3.59 long, 3.32 wide, light brown. Clypeus yellow with two median bristles, 0.52 high.

Chelicerae reddish-brown, laterally depressed and with a large tuft of small white bristles ( Fig. 25). Sternum yellow, with scattered bristles; 1.55 long, 1.64 wide. Labium light brown, yellowish distally, 0.34 long, 0.55 wide.

Abdomen 3.60 long, light brown with two parallel dark brown bands on distal half; with two pairs of sigillae. Venter gray, with scattered bristles. Palpus with an elongated median apophysis with an acute tip ( Figs 98, 99, 100). Ental branch of RTA with a lamellar projection at the base and a slender and thin apex ( Fig. 100); ectal branch of RTA divided in two branches ( Fig. 100).

Chelicerae light brown, with scattered bristles. Sternum yellow, 1.41 long, 1.40 wide. Labium as in male, 0.49 long, 0.48 wide. Legs light brown, unmarked; relative length: I-II-IV-III, I—femur 5.14/ patella-tibia 6.80/ metatarsus 4.56/ tarsus 1.66/ total 18.16; II—4.64/ 6.30/ 4.31/ 1.82/ 17.07; III—3.32/ 3.90/ 2.73/ 1.32/ 11.27; IV—4.31/ 5.64/ 4.06/ 1.82/ 15.83.
