Thaumasia velox Simon, 1898  

Figs 3, 11, 56–67

Thaumasia velox Simon, 1898b: 18   , male holotype from Rio Tocantins, São Paulo de Olivença, Amazonas, Brazil [03°23’S, 68°52’W], de Mathan leg. (MNHN) (examined). F.O. Pickard-Cambridge, 1901: 309, pl. 30, fig. 5. F.O. Pickard- Cambridge, 1903: 154, pl. 14, fig. 1, female from Santarém, Pará, Brazil (MNHN). Sierwald, 1989: 8, figs. 13–16, 59–60. Sierwald, 1990: 25, figs. 16, 21.

Thaumasia annecta Bryant, 1948: 349   , pl. 2, fig. 18, female from Ennery , Haiti, 10.IX.1934, P. J. Darlington (MCZ) (examined). New synonymy.

Thaumasia decemguttata Mello-Leitão, 1945: 245   , fig. 28, two juveniles from Curuzú   GoogleMaps , Cuatiá, Corrientes, Argentina [29°47’S, 58°03’W], M. Birabén ( MLP 16440 View Materials ) (examined). New synonymy.

Newly established junior synonyms of Thaumasia velox   . The epigynum of the female type specimen of T. annecta   is identical to T. velox   . The juvenile types of T. decemguttata   present a wide lateral band formed by short white bristles on the lateral area of carapace and abdomen, as the specimens of T. velox   ( Fig. 6).

Diagnosis. The males of T. velox   resemble those of T. scoparia   in the shape of the median apophysis ( Figs 144, 145), but can be distinguished by the short and ventrally curved tip of the ental branch of RTA ( Figs 58, 59) and also by the lamellar base of EnB ( Fig. 59). The females of T. velox   resemble those of T. caxiuana   sp. nov. ( Fig. 92), T. senilis   ( Fig. 26), T. caracarai   sp. nov. ( Fig. 119) by the general shape of middle field of epigynum ( Fig. 60), but can be distinguished by the slightly excavated lateral portion of the middle field ( Fig. 60) and by the rounded and thickned border of the copulatory duct 2 ( Fig. 61) and by the short and rounded head of spermathecae ( Fig. 62).

Description. Male (Holotype, Amazonas, Brazil, MNHN). Total length 15.42. Carapace 7.84 long, 7.71 wide, light brown with a broad lateral band of white setae; live specimens present a dark green colouration ( Fig. 6).

Ventral pairs of macrosetae on tibiae: I-4; II-4; III-4; IV-4. Abdomen 5.71 long, dark green with several white spots on dorsum, bristly; with two pairs of sigillae. Venter light brown, bristly. Palpus with a small median apophysis with two rounded tips ( Fig. 57); DTP elongated ( Fig. 56). Ectal branch of RTA with a small lamellar projection at the base ( Fig. 59) and ental branch of RTA with a well developed lamellar base and a short and ventrally curved tip ( Figs 58, 59).

Female (Santarém, Pará, Brazil, MNHN). Total length 15.02. Carapace 7.31 long, 6.78 wide, colour as in male. Clypeus as in male, 0.82 high.
