Figs 125–138 ; Map 2

Type material: Holotype: male from Parque Nacional Natural El Tuparro , Cumaribo, Vichada, Colombia (05°21'15.14"N, 67°51'47.3"W), 800 m, forest associated with rocky outcrop, 12–21 March 2011, D. Luna & C. Romero leg. ( ICN 6480, PBI _OON 44554).

Etymology. The specific name is a toponym in apposition referring to the type locality.

Diagnosis. The male is distinguished from all other species of Neoxyphinus by the embolus with an additional, retrolateral process and long spermatic duct, extended beyond the small apical process ( Figs 136, 138 ) and by the presence of spines on leg II.

Description. Male (PBI_OON 44554): total length 1.62. Cephalothorax: carapace dark red-brown, broadly oval, pars cephalica strongly elevated, posterolateral surface without spikes, surface of elevated portion and sides smooth; lateral margin with blunt denticles ( Fig. 129 ); posterior part with two pairs of small tubercles ( Figs 128– 129 ); recurved set of setae on posterior surface with eight small tubercles ( Fig. 128 ). Clypeus margin slightly reborded, straight in frontal view; high ( Fig. 130 ). Sternum as long as wide, orange-brown ( Fig. 131 ); surface smooth. Chelicerae, endites and labium orange-brown. Abdomen: book lung covers large, elliptical. Dorsal scutum dark red-brown, middle surface finely reticulate, sides smooth ( Fig. 133 ), anterior half without projecting denticles. Epigastric and postepigastric scutum orange-brown. Legs: orange-brown. Leg spination: tibia I v6-2 -2; II v2-2 -2; metatarsus I v4-2 -0; II v0-2-2. Genitalia: epigastric region with pore small and narrow. Palp with proximal articles, cymbium and bulb pale orange. Embolus elongated ( Fig. 136 ), with an anterior retrolateral process ( Fig. 138 ) and apical process displaced basally ( Figs 136, 138 ).

Female: Unknown.

Other material examined. None.

Distribution: Known only from the type locality.
