Figs 257–259 , 263–264 , 317 Type material. Holotype : BRAZIL : Amazonas : , Barcelos [ 1.1833 , ‑64.9667 ], Serra do Tapirapecó , 2 October 2006 , A.A. Nogueira leg. ( INPA ). Etymology. The specific name refers to the type locality; noun in apposition. Diagnosis. Females of M. tapirapeco spec. nov. resemble those of M. sanctivincenti comb. nov. ( Figs 250–252 ) and M. zeteki spec. nov. ( Figs 309–311 ) by the epigyne with EP opening medially on MS. They are distinguished from both species by the MS wider than long ( Fig. 257 ) and internal ducts with FW U-shaped and laterad ( Figs 258–259 ) (MS as long as wide and FW sinuous and posteriad in M. sanctivincenti comb. nov. ; EP longer than wide and FW postero laterad in M. zeteki spec. nov. ). Description. Female ( holotype ): Total length 10.8. Prosoma 3.9 long, 3.7 wide. Opisthosoma 6.5 long, 4.1 wide. Eyes: diameters: 0.34, 0.25, 0.19, 0.23; interdistances: 0.25, 0.20, 0.48, 0.41, 0.25, 0.19. Legs: I: 19.4 (5.3, 2.1, 5.2, 5.3, 1.5); II: 20.3 (5.7, 2.2, 5.5, 5.4, 1.5); III: 14.4 (4.3, 1.6, 3.7, 3.5, 1.3); IV: 16.1 (4.6, 1.5, 4.2, 4.4, 1.4). Spination follows the generic pattern. Epigyne: EF wider than long, MAB short and narrow; MS drop-shaped, with lateral margins gently converging anteriorly; LL almost touching posteriorly ( Fig. 257 ). Vulva: GP slightly longer than wide, mediad, arising from ducts at first turn; SP irregular-shaped, with folds; FD antero laterad ( Figs 251–252 , 256–257 ). Male: Unknown. Distribution. Only known from the type locality ( Fig. 317 ).
