Meioneta oculata Millidge, 1991: 103, figs. 413, 414 (Female holotype from Dantas, La Molina, Huanuco, Peru, 270m, May 30, 1987, D. Silva col., deposited in MUSM, examined); Platnick, 2012.
Diagnosis. The male palp of Meioneta oculata Millidge, 1991 resembles that of M. noronhensis Rodrigues, Brescovit & Freitas, 2008 (Rodrigues et al. 2008: figs. 1–4) by the absence of a conical projection of the dorsal cymbial surface and presence of a single distal arm of the paracymbium, but differs by the basal projection of dorsal surface of cymbium and more highly developed mesobasal surface (Figs. 11, 13), more distally developed and ventrally elongated lamella characteristica (Figs. 11, 12) and absence of a retrolateral tibial apophysis (Fig. 11).
Description. Male (MUSM ENT 00503951): Total length 1.26. Carapace length 0.56, width 0.48. Clypeus height 0.10. Sternum length 0.33, width 0.33. Chelicerae length 0.27. Abdomen length 0.73, width 0.46, height 0.48. Leg formula I/IV/II/III; segment lengths (I/II/III/IV): femora 0.67/0.56/0.52/0.63; patellae 0.18/0.14/0.12/0.14; tibiae 0.71/0.65/0.46/0.60; metatarsi 0.63/0.54/0.42/0.60; tarsi 0.44/0.42/0.31/0.37; total 2.63/2.31/1.83/2.34. Palp (femur, patella, tibia, cymbium): 0.25/0.08/0.10/0.29. Coxa IV bases well separated (0.08). Metatarsal trichobothria I–III present, IV absent. TmI 0.30. Eye diameters and interdistances: AME 0.03, ALE and PLE 0.06, PME 0.07; AME–ALE 0.01, PME–PLE 0.02, AME–AME 0.01, PME–PME 0.03. Eyes margined with black (Fig. 14). Carapace pale orange, with setae behind eyes, longer than wide. Chelicerae and endites pale orange. Labium olive. Sternum olive-green. Coxa, sternum and endites with setae. Chelicerae promargin with three teeth, retromargin with three small teeth. Legs pale orange. Abdomen yellow, posteriorly brown, longer than wide, venter brown. Spinnerets and colulus dark brown. Colulus well developed. Palp with cymbium basally elongate and with vertical mesobasal portion very broad and triangularly produced proximally (Figs. 12, 13). Embolic membrane present (Fig. 11). Lamella characteristica well developed, projected ventrally (Fig. 11). Distal suprategular apophysis short, hook-like (Fig. 11). Paracymbium ectally with an excavation sclerotized next of tibia (Figs. 11, 13).
Variation. Males (n=3). Total length 1.26–1.28; carapace length 0.56–0.58. The color pattern is quite variable from pale orange to orange-brown in carapace and abdomen yellow to yellow-brown in males.
