Meri zeteki spec. nov.
Figs 309–314, 317
Type material. Holotype: PANAMA: Panama Oeste: ♀, Barro Colorado Island [9.1636, ‑79.8378], Canal Zone, 1–4 July 1950, A.M. Chickering leg. (MCZ 99617).
Etymology. The specific name honors Dr. James Zeteki, Founding Director of the Canal Zone Biological Area, located on Barro Colorado Island in Panama; name in genitive case.
Diagnosis. Females of M. zeteki comb. nov. resemble those of M. sanctivincenti comb. nov. (Figs 250–252) and M. tapirapeco spec. nov. (Figs 257–259) by the epigyne with EP opening medially on MS. They are distinguished from both species by the epigyne with transversal anterior groove, MS with anterior margins bottlenecked (Fig. 309) and by the vulva with FW postero laterad, liver-shaped (Figs 310–311) (anterior groove absent in the latter species; MS with lateral margins diverging and FW posteriad in M. sanctivincenti comb. nov.; MS with anterior margins gently converging and FW U-shaped and laterad in M. tapirapeco spec. nov.). Males are unknown.
Description. Female (holotype): Total length 18.8. Prosoma 6.9 long, 6.2 wide. Opisthosoma 11.5 long, 7.3 wide. Eyes: diameters: 0.50, 0.40, 0.33, 0.37; interdistances: 0.40, 0.24, 0.65, 0.70, 0.35, 0.25. Legs: I: 26.8 (7.7, 3.2, 7.0, 7.1, 1.8); II: 28.6 (8.3, 3.5, 7.5, 7.4, 1.9); III: 19.6 (6.4, 2.7, 4.9, 4.7, 1.6); IV: 24.0 (7.5, 2.6, 6.0, 6.0, 1.9). Spination follows the generic pattern except metatarsus IV: r1-1-2. Epigyne: EF wider than long; MAB present, embedded in epigynal field; MS longer than wide, roughly drop-shaped; EP roughly as long as wide with lateral margins extending posteriorly to lateral margins of MS (Fig. 309, 313). Vulva: GP longer than wide, antero-mediad; SP elongate with few surface folds; FD antero-mediad (Figs 310–311, 314).
Male: Unknown.
Distribution. Only known from the type locality (Fig. 317).
