Thaumasia abrahami Mello-Leitão, 1948  

Figs 3, 14, 80–87

Thaumasia abrahami Mello-Leitão, 1948: 152   , fig. 1, female holotype from Yawakuri river   GoogleMaps , Upper Demerara-Berbice Guyana [05°18’N, 58°22’W], July 1919, A. A. Abraham leg., deposited in BMNH (examined).

Note. The match between males and females was made after the examination of the female holotype, since many males and females were found together in the same vial in some Brazilian collections.

Diagnosis. The females of T. abrahami   resemble those of T. onca   sp. nov. ( Fig. 107) and T. hirsutochela   sp. nov. ( Fig. 107) in the general shape of the middle field ( Fig. 80), but can be distinguished by “hood-like” shape of the middle field ( Fig. 80), by the conspicuous hood ( Fig. 80) and by the shape and the projected pores on the head of spermathecae ( Figs 81, 82). The males resemble those of T. caxiuana   sp. nov. in the shape of the apex of the median apophysis ( Fig. 89), but can be distinguished by the slightly longer median apophysis ( Fig. 84) and by the longer and triangular shape of the ectal branch of RTA ( Figs 85–87).

Description. Female (Holotype, Guyana, BMNH). Total length 9.44. Carapace 3.81 long, 3.32 wide, yellow; unmarked. Clypeus yellow, 0.51 high. Anterior eye row straight, 0.98 wide; posterior recurved, 1.22 wide.

Chelicerae yellow. Sternum yellow, with scattered bristles; 1.82 long, 1.90 wide. Labium yellow, 0.40 long, 0.55 wide. Legs yellow, unmarked, with numerous dark brown macrosetae; relative length: I-II-IV-III, I—femur 6.72/ patella-tibia 9.57/ metatarsus 6.78/ tarsus 2.52/ total 25.59; II—7.05/ 9.31/ 6.65/ 2.50/ 25.51; III—5.81/ 7.04/ 5.05/ 1.99/ 19.89; IV—6.73/ 8.11/ 6.74/ 2.65/ 24.23.

Abdomen 4.64 long, light brown with an irregular dark brown patch on cardiac area; with scattered bristles and two pair of sigillae. Venter yellow, with scattered bristles. Epigynum with a well developed “hood-like” middle field ( Fig. 78) and an acute posterior margin ( Fig. 80). Head of spermathecae with slightly projected pores ( Fig. 82) and short copulatory ducts ( Fig. 81).

Male (Una, Bahia, Brazil, IBSP 47144). Total length 8.13. Carapace 3.81 long, 3.32 wide, as in female. Clypeus yellow, 0.40 high. Anterior eye row straight, 0.98 wide ( Fig. 14); posterior recurved, 1.20 wide. Eye diameters, interdistances, and median ocular quadrangle: AME 0.22, ALE 0.12, PME 0.20, PLE 0.18; AME-AME 0.10, AME-ALE 0.14, PME-PME 0.20, PME-PLE 0.22, OQA 0.52, OQP 0.62, OQH 0.51. Chelicerae yellow, with scattered white bristles ( Fig. 14). Sternum yellow, 1.82 long, 1.90 wide. Labium as in female, 0.33 long, 0.66 wide. Legs yellow, unmarked; relative length: I-II-IV-III, I—femur 8.77/ patella-tibia 12.23/ metatarsus 9.70/ tarsus 3.19/ total 33.89; II—8.64/ 11.30/ 8.40/ 2.92/ 31.26; III—6.65/ 7.98/ 5.98/ 2.26/ 22.87; IV—7.98/ 9.97/ 8.77/ 3.30/ 30.02. Ventral pairs of macrosetae on tibiae: I-5; II-5; III-4; IV-4. Abdomen 4.06 long, colouration as in female. Palpus with a rounded apex of the median apophysis ( Fig. 84); distal tegular projection short ( Fig. 84).
