Diagnosis

The females of this species most closely resemble Selenops isopodus found in Colombia and Selenops arikok sp. n., of which the males are unknown. Females can be distinguished from these species by the epigyne, as Selenops curazao has a narrow septum, and the internal copulatory organs are quite different (Figs 5–6). The male is easily differentiated from other species by the angular cymbium, the long twisted stalk of the conductor, and the shape of the tibial apophyses (Figs 3–4)

Natural history

This species has been collected under wood, rocks, cactus and other debris on the ground, as well as on, in, and near buildings, including houses. In houses it is common at night around the ceiling molding where it hides during the day. It has been found in dry, thornscrub habitat, dominated by Acacia (Fig. 196). The egg sac is flat, white, and disc-shaped, and is guarded by the female. One specimen laid 30–40 eggs which hatched about 2 weeks later. After about a week, the spiderlings emerged from the egg sac. The mother died about a week later.

Distribution
