TYPES: Male holotype, 53 8♀ paratypes from Rio Samiria (4°43'S, 74°18'W), Dept. Loreto, Peru GoogleMaps ; May 21–28, 1990 (D. Silva ‘‘& Ernesto ’’), in MUSM .

ETYMOLOGY: The species name is a noun in apposition honoring the Ocaina, who were once a large tribe in northern Peru and southern Colombia. They were devastated by the rubber boom of around 1900, and today number only a few hundred people.

DIAGNOSIS: Close relative of C. paraguaensis , but with additional modified hairs distally on the male chelicerae (fig. 955); further distinguished by details of the procursus (figs. 958–959).

MALE (holotype): Total length 4.4, carapace width 1.8; leg 1: 50.2 (12.3+0.6 +11.9+23.1+2.3), tibia 2: 7.1, tibia 3: 5.1, tibia 4: 6.3; tibia 1 l/d: 74. Habitus very similar to C. fowleri (cf. fig. 962); distance PME-ALE about 50% of PME diameter. Carapace orange-ochre, slightly darker behind ocular area, clypeus slightly darker medially; sternum orange. Chelicerae with pair of large apophyses proximally (fig. 955; not as prominent as in C. paraguaensis , cf. fig. 948), each provided with ~ 40 modified hairs (figs. 19–20); ~ 10 further modified hairs more distally, and pair of small distal apophyses (fig. 955). Palps in general as in C. fowleri (cf. figs. 963–964), procursus simple (figs. 958–959), bulb with conspicuous whitish globular area dorsally on embolar division, and strong apophysis (fig. 956). Tarsal organ exposed. Legs brown, only tips of tibiae whitish, and area around patellae lighter, no dark rings; legs without spines and vertical hairs, with many curved hairs (femur 1 dorsally, tibia 1 dorsally and ventrally, tibia 4 dorsally, not on tibiae 2 and 3, not on metatarsi); retrolateral trichobothrium of tibia 1 at 3%; tarsus 1 with ~ 30 pseudosegments. Opisthosoma monochromous greenish-ochre, shape as in C. fowleri (cf. fig. 962); gonopore without epiandrous spigots (fig. 131); ALS with only one piriform gland spigot each (fig. 179).

VARIATION: Tibia 1 in 7 other males from type locality: 11.3–12.3 (x¯ = 11.6), tibia 1 in 8 males from Manaus: 9.9–10.9 (x¯ = 10.4); some males (apparently more recently molted individuals) with lighter legs and dark spots on opisthosoma.

FEMALE: In general similar to male, but legs with dark rings on femora (subdistally) and tibiae (proximally and subdistally). Tibia 1 in 11 females from type locality: 8.3–9.6 (x¯ = 8.8). Opisthosoma with several dark spots laterally, sometimes also dorsally. Epigynum and internal genitalia as in figs. 960– 961; most females with conspicuous plug.

DISTRIBUTION: Known from northern and central Peru and northwestern Brazil (map 7).
