Diagnosis. Males of Otiothops besotes sp. n. resemble those of O. brevis Simon, 1893 by size of the palpal tibia, which is wider than the bulb ( Figs 2–4 ; see also Platnick 1975, figs 61–62), but can be distinguished by the globeshaped tibia and straight embolus ( Figs 2–4 ). The female internal genitalia ( Fig. 5 ) resemble those of O. birabeni Mello-Leitão, 1945 by the presence of latero-median poreplates ( Fig. 5 ; see also Brescovit and Bonaldo 1993, fig. 4), but differ by the wider anterior portion of the median receptacles, and by the shorter poreplates with a ringed texture.

Etymology. The specific epithet is a noun in apposition referring to the type locality at ‘Los Besostes’, Valledupar, Cesar, Colombia.

Description. Male (holotype, ICN-Ar10652): Total length 3.8. Carapace: 1.85 long, 1.35 wide (at leg II), 0.85 high (at leg II). Leg I: femur 1.24 long, 0.62 wide. Abdomen: 1.95 long, 1.45 wide. Posterior median eyes contiguous. Palp: femur 0.48 long, 0.16 wide; patella 0.24 long, 0.22 wide; tibia 0.26 long, 0.34 wide, cymbium 0.4 long, 0.1 wide; embolus 0.38 long. Sclerotized portions of body dark orange; abdominal scute dark orange, unsclerotized portion of dorsal abdomen grey with light spots. Palpal femur thickened; tibia globe-shaped, 2.0 x wider than bulb; embolus longer than bulb, slightly curved at tip ( Figs 2–4 ).

Female (paratype, ICN-Ar10653): Total length 5.2. Carapace: 2.25 long, 1.64 wide (at leg II), 1.05 high (at leg II). First leg: femur 1.42 long, 0.74 wide.

Sclerotized portions of body dark orange; abdominal scute dark orange, unsclerotized portion of dorsal abdomen grey with light spots. Genitalia ( Fig. 5 ): anterior half of receptacles 2.0 x wider than posterior half, basally joined; pedicel with posterior apodemes; poreplates discoid shaped.
