Family Chactidae Pocock, 1893

Broteochactas trezzii (Vignoli and Kovařík, 2003) : VENEZUELA. Habitat: under a stone inside Sima Aonda, a long narrow gorge, ca. 50 m deep, the remains of a cave, the ceiling of which collapsed; the biotope was characterized as dark and extremely humid. Troglomorphies: median ocelli reduced; pigmentation and sclerotization reduced; pedipalps, legs, and metasoma attenuate; prolateral and retrolateral pedal spurs absent; telson vesicle enlarged. Previous assessments: troglobite (Vignoli and Kovařík, 2003; Rojas-Runjaic, 2004; Galan and Herrera, 2006; Vignoli and Prendini, 2009); perhaps a troglobite (Volschenk and Prendini, 2008). Current assessment: endogean. Citations: Vignoli and Kovařík (2003); Rojas-Runjaic (2004); Galan and Herrera (2006); Volschenk and Prendini (2008); Ochoa et al. (2010); Rossi (2018a); Ochoa and Rojas-Runjaic (2019). Remarks: A monotypic genus of dubious validity, Antridiscalceatus Rossi, 2018 , was erected to accommodate this species; it is retained in the genus Broteochactas Pocock, 1893 , in the present contribution.

Chactas vilorai Rojas-Runjaic, 2004 : VENEZU- ELA. Habitat: under stones, hypogean, twilight zone. Previous assessments: trogloxene (Rojas- Runjaic, 2004); troglóxenas y troglófilas (Galan and Herrera, 2006). Current assessment: hypogean: troglophile (eutroglophile). Citations: Rojas-Runjaic (2004); Galan and Herrera (2006).

Chactas vanbenedenii (Gervais, 1843) : COLOMBIA, VENEZUELA. Habitat: inside cave; surface. Previous assessments: troglófila (Galan and Herrera, 2006). Current assessment: epigean, hypogean: accidental. Citations: Galan and Herrera (2006).

Chactas yupai González-Sponga, 1994 : VENEZUELA. Habitat: high altitude tropical forest and savanna. Previous assessments: troglóxenas y troglófilas? (Galan and Herrera, 2006). Current assessment: epigean: accidental. Citations: González-Sponga (1994); Galan and Herrera (2006).
