Walckenaer, 1837: 561 . O. Pickard-Cambridge, 1897: 94 . Simon, 1898a: 313 . Petrunkevitch, 1928: 104 . Type species. Thaumasia senilis Perty, 1833 , by original designation. Diagnosis. The males of Thaumasia can be distinguished from those of Architis ( Santos, 2007b , fig. 2A) and Tinus ( Carico, 1976 , fig. 8) by the well developed distal tegular projection and median apophysis and by the very long embolus ( Figs 34 , 52 , 56 , 76 , 84 , 88 , 98 , 111 , 115 , 125 , 130 , 140 , 144 ). The females can be distinguished from the latter genera by the epigynum with a slightly projected and laterally excavated middle field ( Figs 26 , 44 , 60 , 68 , 80 , 92 , 103, 104, 107 , 119 , 134, 137 ), by the slightly developed lateral lobes ( Fig. 60 , 68 , 80 , 92 , 103, 104, 107 , 119 , 134, 137 ), by the conspicuous copulatory ducts (CD1 and CD2) ( Figs 40 , 45 , 61 , 71 , 81 , 93 , 105, 108 , 121 , 135, 138 ) and by the small, rounded head of spermathecae ( Figs 42 , 62 , 73 , 82 , 94 , 106 ). Description. Small ( Thaumasia argenteonotata ) to large spiders ( Thaumasia oriximina sp. nov. , Figs 7, 8 , and T.velox , Fig. 6 ). Anterior eye row straight to slightly procurved, posterior recurved ( Figs 10–25 ). PLE and PME always larger than other eyes ( Figs 10–25 ). Chelicerae light brown to reddish-brown ( Figs 10–25 ), with a lateral tuft of small to long white bristles in males of most species ( Figs 10–25 ); promargin with three equidistant teeth, the central tooth is twice the size of each lateral; retromargin with three teeth ( Fig. 47 ). Sternum smooth, with scattered bristles. Labium usually smooth and light brown. Legs long and slender, leg III always the shortest. Tibiae I with conspicuous ventral pairs of macrosetae varying from four to five. Trichobothria of metatarsi with a smooth hood ( Fig. 95 ). Superior tarsal claws with eight to eleven teeth ( Figs 43 , 49 , 66 , 75 , 83 , 97 , 102 , 110 , 118 , 124 , 129 , 139 ) and inferior with one or two teeth ( Figs 67 , 129 ). Abdomen longer than wide, dorsum with one to two pairs of sigillae. Male palpi with an elongated cymbium ( Figs 32 , 36 , 52 , 56 , 78 , 85 , 90 , 98 , 113 , 116 , 126 , 132 , 142 , 146 , 150 , 152 ), median apophysis conspicuous and with a large distal tegular projection ( Figs 31 , 34 , 52 , 56 , 76 , 84 , 88 , 98 , 111 , 115 , 125 , 130 , 140 , 145 , 148 , 152 ); retrolateral tibial apophysis divided into an ental and an ectal branches ( Figs 37 , 53 , 59 , 79 , 86 , 91 , 100 , 114 , 116 , 127 , 133 , 143 , 147 , 151 , 153 ). Female epigynum with a slightly projected and laterally excavated middle field and a hood visible in ventral view ( Figs. 44 , 60 , 68 , 80 , 92 , 104, 107 , 119 , 134, 137 , 154 ); copulatory ducts divided in CD1 and CD2 ( Figs 41 , 45 , 61 , 71 , 81 , 93 , 105, 108 , 122 , 135, 138 , 155 ), pocket membranous ( Fig 27 , 45 , 61 , 72 , 81 , 93 , 105, 108 , 122 , 135, 138 , 155 ) and head of spermathecae conspicuous,with apical pores ( Figs 42 , 62 , 73 , 82 , 94 , 106 ). Distribution. Mexico to Argentina ( Figs. 1–4 ). Composition . 17 species, ten of them newly described here.
