Family Hormuridae Laurie, 1896

Hormurus polisorum (Volschenk et. al., 2001): AUSTRALIA (Christmas Island). Habitat: inside cave. Troglomorphies: median ocelli reduced or absent; lateral ocelli reduced; pigmentation and sclerotization reduced; pedipalps, legs, and metasoma attenuate; telson vesicle enlarged. Previous assessments: troglobitic (Humphreys, 2001); troglobite (Volschenk et al., 2001; Volschenk and Prendini, 2008; Moulds and Bannik, 2012). Current assessment: hypogean: troglobite. Citations: Humphreys (2001); Volschenk et al. (2001); Volschenk and Prendini (2008); Moulds and Bannik (2012).

Opisthacanthus pauliani Lourenço and Goodman, 2008 : MADAGASCAR. Habitat: inside cave, 30 m from entry. Previous assessments: obligate cave-dwelling animal, may represent second tro- globitic scorpion species in Madagascar (Lourenço and Goodman, 2008). Current assessment: epigean, hypogean: accidental. Citations: Lourenço and Goodman (2008). Remarks: The faded coloration of this old specimen is likely due to age and preservation although several epigean Malagasy hormurids are relatively pale in color, e.g., Palaeocheloctonus pauliani Lourenço, 1996 . This species is likely to be conspecific with one of several common epigean Malagasy hormurids.
