Type specimens. Holotype male from west side of the Metica river , [La Molinera sector], Villanueva, Casanare, Colombia, 220 m, 4.315584°N, 72.632862°W, 8.I.2016, D. Molina & S. Galvis (ICN-Ar 8305), deposited in the Arachnological Collection of the Instituto de Ciencias Naturales of the Universidad Nacional de Colombia (ICN-Ar, Eduardo Flórez), Bogotá . Paratype: one male from km 4.5 road to San Francisco, El Caduceo Natural Reserve , San Martín, Meta, Colombia, [368 m above sea level], 3,671389°N, 73,659444°W, 30 .IX-4 .X.2013, D.

Etymology. The species epithet ( casanare , noun in apposition) is taken from the type locality, which in words of the indigenous groups of this region, the Sáliva or Sáliba people, of the Piaroa-Saliban family of languages, means blackwater river, in reference to the Metica (or Meta) river, one of the most important rivers in the country.

Diagnosis. The male C. casanare can be easily disguished from C. damborskyae by their more slender and longer retroventral apophysis (RvTA), with the retrolateral tibial apophysis (RTA) longer, more slender and distally quadrangular ( Figures 1 a-d).

Description of male (holotype). Total length: 5.09 (paratype 5.29). Carapace reddish-brown with black borders and a dorsal and medial mark with the shape of an inverted “V” and dispersed orange-brown hairs, 1.95 long (paratype 1.98 long), 1.60 wide, 0.88 high. Dorsal eye field with same color as the carapace but with one anterior median and two lateral pairs of white wide marks, 1.44 long, with anterior and lateral orange-brownish hairs. Anterior eye row 1.44 wide, posterior 1.46 wide ( Figures 1 e-f). Sternum yellow, 0.86 long, 0.59 wide. Labium dark brown, 0.35 long, 0.29 wide. Chelicerae brown, vertical, with three teeth (the median much larger) on promargin and one large tooth on retromargin. Legs IV.I.III.II. Leg segment lengths (from femur to tarsus): I, 1.14 + 0.72 + 0.76 + 0.50 + 0.37; II, 1.00 + 0.58 + 0.63 + 0.49 + 0.34; III, 1.00 + 0.55 + 0.61 + 0.60 + 0.32; IV, 1.31 + 0.58 + 0.88 + 0.89 + 0.42. Leg I reddish-brown with yellowish metatarsus-tarsus. Femur I-II dorsally blackish, femur-tibiae I-II prolaterally blackish, legs III-IV yellowish, coxa I-IV with proximal blackish marks. Leg macrosetae: femur, I d 0-0-1-1-1, p 1 di; II d 0-0-0-1-1, p 1 di; III d 1 di, p 0-0-0-1-1, r 1 di; IV d 1 di, p 0-0-0-1-1; tibia, I v 0-0-0-2-2; metatarsus, I-II v 2-2; III v 1 di, p 1 di, r 1 di. Tibia I with two pairs of ventral bulbous setae in 2-2-0-0-0 disposition. Abdomen ventrally brown, and dorsally brown with a dorsal whitish longitudinal stripe, and some dorsal and lateral white marks, likely guanine accumulations ( Figures 1 e-f). Spinnerets brownish and long.

Known only from the eastern departments of Casanare (Villanueva) and Meta (San Martín), Colombia ( Figure 2 ) .
