Figures 25–32, 46, 82–98, 102

TYPE: Male holotype, female allotype and one male paratype from Berlese and sifted leaf litter of a littoral forest at an elevation of 25 m, Forêt d’Ampombofofo, 21°5′58″S, 49°20′19″E, Antsiranana Province, Madagascar (21–22 November 2007, B.L. Fisher et al.), deposited in CASC (PBI_OON 36120).

ETYMOLOGY: The species epithet, a noun in apposition, is taken from the Malagasy word for cow, omby.

DIAGNOSIS: N. omby can be differentiated from other Noideattella species by the reduced size of the eyes covering less than half of the cephalic area; except from N. tany and N. sylvnata that have similar eye size and arrangement (Álvarez-Padilla et al., 2012: figs. 1, 201); but differ from these two species by the presence of a cuticular rectangular apophysis on the embolar lamella (figs. 46, 95–98) and the smooth carapace dorsal surface (figs. 25, 27, 82).

DESCRIPTION: Male (PBI _ OON 3564). Total length 1.2. Body color pale orange (figs. 25–27). Cephalothorax: Carapace pale orange, ovoid in dorsal view, pars cephalica flat in lateral view, anteriorly narrowed to 0.49 times its maximum width or less, posterolateral edge without pits, surface of elevated portion of pars cephalica smooth, sides finely reticulate; lateral margin without denticles (figs. 25, 27, 82, 83). Sternum surface and furrows cuticle smooth (figs. 26, 88). Clypeus straight in front view. Ocular area equal than the clypeus height (fig. 29). Eyes well developed, ALE largest; posterior eye row straight from front; ALE-PLE separated by less than ALE radius, PLE-PME separated by less than PME radius (figs. 29, 94). Sternum longer than wide, pale orange (fig. 26), without pits, microsculpture absent, anterior margin 2001 to Apr. 14, 2001, Fisher et al., 1♀ (CASC PBI _ OON 3878). Toliara: Forêt d’Petriky, 12.5 km W Tolagnaro, littoral rainforest, 10 m, -25.06216°, 46.86933°, Nov. 22, 1998, Sylvian, B.L. Fisher, 2♀ (FMNH PBI _ OON 36302).
