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.
