Family Scorpiopidae Latreille, 1802

Alloscorpiops troglodytes Lourenço and Pham, 2015 : VIETNAM. Habitat: inside cave, approximately 60 m from entry. Current assessment: hypogean: trogloxene (subtroglophile). Citations: Lourenço and Pham (2015). Remarks: Although Kovařík et al. (2020) transferred this species to Scorpiops Peters, 1861 , it is retained in Alloscorpiops Vachon, 1980 , in the present contribution.

Euscorpiops cavernicola Lourenço and Pham, 2013 : VIETNAM. Habitat: inside cave, 120 m from main entrance, on walls of cave. Previous assessments: presents most features of genus Euscorpiops Vachon, 1980 , but may represent first Scorpiopinae Latreille, 1802 , species exhibiting certain adaptations to cave life (Lourenço and Pham, 2013). Current assessment: hypogean: trogloxene (subtroglophile). Citations: Lourenço and Pham (2013); Pham (2016). Remarks: Although Kovařík et al. (2020) transferred this species to Scorpiops Peters, 1861 , it is retained in Euscorpiops in the present contribution.

Euscorpiops dakrong Lourenço and Pham, 2014 : VIETNAM. Habitat: inside cave, 60–70 m from entrance. Previous assessments: some morphological features indicate certain degree of adaptation to cave life (Lourenço and Pham, 2014b). Current assessment: hypogean: trogloxene (subtroglophile). Citations: Lourenço and Pham (2014a). Remarks: Although Kovařík et al. (2020) transferred this species to Scorpiops Peters, 1861 , it is retained in Euscorpiops in the present contribution.

Plethoscorpiops profusus Lourenço, 2017 : MYANMAR. Habitat: inside cave, about 90 m from entry, hidden in wall crevices. Current assessment: hypogean: trogloxene (subtroglophile). Citations: Lourenço (2017b). Remarks: Although Kovařík et al. (2020) transferred this species to Scorpiops Peters, 1861 , it is retained in Plethoscorpiops Lourenço, 2017 in the present contribution.

Troglocormus ciego Francke, 1981 : MEXICO. Habitat: inside cave. Troglomorphies: median ocelli absent; lateral ocelli reduced; pigmentation and sclerotization reduced; pedipalps and legs attenuate; telson vesicle enlarged. Previous assessments: troglobite (Francke, 1981; Armas, 1994; Volschenk and Prendini, 2008; Sissom and Reddell, 2009); troglobie (Lourenço and Francke, 1985); troglobio (Palacios-Vargas and Reddell, 2013).
