TYPE: Female holotype from Arima Valley , Trinidad ; 800–1200 ft elev., Feb. 10–22, 1964 ( P. Wygodzinski & J. Rozen ), in AMNH , examined . DIAGNOSIS: Distinguished from C. merida by the more proximal cheliceral apophyses (fig. 1321), and the broad procursus with its two short distal projections (fig. 1323). MALE (Simla, Arima Valley): Total length 1.1, carapace width 0.53; leg 1: 7.10 (1.84+0.19+1.97+2.29+0.81), tibia 2: 1.08, tibia 3: 0.84, tibia 4: 1.06; tibia 1 l/d: 42. Habitus and prosoma shape as in figs. 1315– 1318. Entire prosoma light brown. Carapace with distinct thoracic groove (fig. 1317); six eyes on slightly elevated ocular area; distance PME-ALE about 60% of PME diameter. Sternum with pair of anterior humps (fig. 1318). Chelicerae with very short entapophyses, and pair of simple anterior apophyses (fig. 1321; see also fig. 33). Palps as in figs. 1319–1320; with distinct retrolateral coxal apophysis, femur proximally with rounded protrusion, distally with apophysis on ventral side (fig. 1322); procursus relatively simple, with two distal protrusions (fig. 1323), bulb with distinct apophysis on embolar division (figs. 1319, 1324). Tarsal organ exposed. Legs light brown; without rings, without spines and curved hairs; with few vertical hairs on femur 1 and tibia 1; retrolateral trichobothrium of tibia 1 at 26%; tarsus 1 with ~ 15 pseudosegments. Opisthosoma globular, grayish; ALS with only one piriform gland spigot each. VARIATION: Tibia 1 in 12 males : 1.77–1.90 (x¯ = 1.83). Opisthosoma rarely with some faint dark spots dorsally. FEMALE: Very similar to male, but without humps on sternum. Epigynum light brown, small in relation to opisthosoma, very simple externally (figs. 1325–1326); internal genitalia as in fig. 1327. Tibia 1 (N = 10) 1.26– 1.35 (x¯ = 1.28); tibia 1 in female holotype : 1.24. DISTRIBUTION: Known only from Trinidad .

Left palp, prolateral view. 1320 . Left palp, retrolateral view. Scale lines: 0.5 mm (1315), 0.2 mm (1316–1320). m elev., cloud forest, June 24–Aug. 2, 1989 (S. & J. Peck), in AMNH . ETYMOLOGY: Named for the city close to the type locality. The specific name is a noun in apposition. DIAGNOSIS: Distinguished from C. arima by the more distal cheliceral apophyses (fig. 1330), and the procursus with its two black tips (fig. 1331). MALE ( holotype ): Total length 1.4, carapace width 0.72; leg 1: 10.1 (2.5+0.3+2.7 +3.6+1.1), tibia 2: 1.5, legs 3 and 4 missing; tibia 1 l/d: 50. Habitus very similar to C. arima (cf. fig. 1315), but with slightly higher ocular area (more like that of Blancoa piacoa , cf. fig. 1333); distance PME-ALE about 60% of PME diameter. Entire prosoma light brown. Sternum with pair of anterior humps. Chelicerae orange-ochre with very short entapophyses, and pair of blackish anterior apophyses (fig. 1330). Palps as in figs. 1328– 1329; orange-ochre to light brown, with distinct retrolateral coxal apophysis, femur proximally with rounded protrusion, distally widened with sclerotized rim ventrally; procursus relatively simple, with two blackish distal tips (fig. 1331), bulb with distinct apophysis on embolar division (figs. 1328– 1329). Legs ochre-yellow, without rings; without spines and curved hairs; with few vertical hairs on tibiae; retrolateral trichobothrium of tibia 1 at 26%; tarsus 1 with ~ 15 pseudosegments. Opisthosoma slightly shrunken, apparently globular as in C. arima (cf. fig. 1315), dark greenish-gray with large dark spots dorsally. Figs. 1321–1327. Canaima arima (Gertsch) . 1321 .
