Figs 114–122 Gen.n. Ven01: Eberle et al. 2018 (molecular data); Huber et al. 2018: fig. 2. Type material . VENEZUELA : ♂ holotype , ZFMK ( Ar 20620), Bolívar , forest near Salto El Sapo at Canaima ( 6°14.5’N , 62°51’W ), ~ 400 m a.s.l. , 9.xii.2002 ( B.A. Huber ) . Other material examined . VENEZUELA : 3♂ 3♀ , ZFMK (Ar 20621), and 4♀ in pure ethanol, ZFMK (Ven02/100-1), same data as holotype . Etymology . The species name is derived from the type locality; noun in apposition. Diagnosis . Distinguished from other New World Ninetinae by the combination of (1) procursus distally widened and provided with sclerotized scales ( Fig. 118 ); (2) genital bulb with small apophysis ( Fig. 117 ); (3) male chelicerae with stridulatory ridges and pair of simple frontal apophyses ( Figs 119–120 ); (4) presence of shallow thoracic furrow ( Fig. 119 ), and (5) male sternum with pair of anterior humps ( Fig. 119 ). Distinguished from sister genus Kambiwa by length of procursus (procursus in Kambiwa consistently short, i.e. shorter than genital bulb) and very short retrolatero-dorsal bulbal apophysis (in Kambiwa consistently long and curved). Description. Male ( holotype ). MEASUREMENTS. Total length 1.12, carapace width 0.52. Distance PME-PME 45 µm; diameter PME 55 µm; distance PME-ALE 20 µm; distance AME-AME 10 µm, diameter AME 30 µm. Leg 1: 2.68 (0.74 + 0.18 + 0.68 + 0.72 + 0.36), tibia 2: 0.58, tibia 3: 0.52, tibia 4: 0.76; tibia 1 L/d: 10. COLOR (in ethanol). Prosoma and legs ochre-yellow, only thoracic furrow slightly darker. Abdomen ochregray, with indistinct darker spots. BODY. Habitus as in Figs 115–116 . Ocular area barely elevated, only posteriorly separated from carapace, thoracic furrow present ( Fig. 119 ); clypeus unmodified. Sternum slightly wider than long (0.36/0.32), with distinct pair of anterior humps ( Fig. 119 ). CHELICERAE. With pair of simple frontal apophyses and stridulatory ridges ( Figs 119–120 ). PALPS. As in Figs 117–118 ; coxa unmodified, trochanter with ventral rounded projection, femur proximally with stridulatory pick (modified hair), tibia widened, procursus distally widened and provided with sclerotized scales, bulb with short hooked apophysis and membranous embolar division ( Fig. 117 ). Legs. Without spines and curved hairs, few vertical hairs; retrolateral trichobothrium of tibia 1 at 58%; tibia 1 without prolateral trichobothrium (present on other tibiae); tarsus 1 with 4–5 pseudosegments. Male (variation). Tibia 1 in 3 other males: 0.67, 0.68, 0.72. Female . In general similar to male but without humps on sternum. Tibia 1 in 7 females : 0.66–0.70 (mean 0.68). Epigynum simple externally ( Figs 114 , 121 ), apparently with pair of small pore plates ( Fig. 122 ). ALS with one widened, one pointed, and several cylindrically shaped spigots. Distribution . Known from type locality only ( Fig. 345 ). Natural history . This species was found in the leaf litter, on the undersides of dead leaves.
