Family Pseudochactidae Gromov, 1998

Aemngvantom lao (Lourenço, 2012) : LAOS. Habitat: inside cave. Troglomorphies: median and lateral ocelli absent; pigmentation and sclerotization absent; pedipalps, legs, and metasoma attenuate; tibial spurs absent; telson vesicle enlarged. Previous assessments: troglobiont (Lourenço, 2012a); troglobite (Lourenço, 2012b; Beron, 2015; Lourenço et al., 2018); troglobitic element (Pham et al., 2017); strong troglomorphic features (Steiner, 2013). Current assessment: hypogean: troglobite. Citations: Lourenço (2012a, 2012b); Steiner (2013); Beron (2015); Pham et al. (2017); Lourenço et al. (2018); present contribution.

Aemngvantom thamnongpaseuam , sp. nov.: LAOS. Habitat: inside cave. Troglomorphies: median and lateral ocelli absent; pigmentation and sclerotization absent; pedipalps, legs, and metasoma attenuate; tibial spurs absent; telson vesicle enlarged. Current assessment: hypogean: troglobite. Citations: present contribution.

Troglokhammouanus steineri Lourenço, 2007 : LAOS. Habitat: inside cave. Troglomorphies: pigmentation and sclerotization present (two individuals partially or entirely depigmented). Previous assessments: troglobite (Lourenço, 2012b; Beron, 2015); found 2000–3000 m from main cave entrance, but its morphological characteristics are not those of a troglobitic element (Lourenço, 2012a); morphological characteristics do not correspond to a troglobitic element (Lourenço and Pham, 2012); found in caves and considered troglomorphic or troglobitic (Soleglad et al., 2012); troglobitic element (Pham et al., 2017); although this species was found inside a cave, its morphological characteristics do not correspond to a totally troglobitic element (Lourenço et al., 2018). Current assessment: hypogean: troglophile (eutroglophile). Citations: Lourenço (2007a, 2007b, 2012a, 2012b, 2017a); Lourenço and Pham (2010, 2012); Soleglad et al.

Vietbocap canhi Lourenço and Pham, 2010 : VIETNAM. Habitat: inside cave. Troglomorphies: median and lateral ocelli absent; pigmentation and sclerotization absent; pedipalps, legs, and metasoma attenuate; tibial spurs absent; telson vesicle enlarged. Previous assessments: troglobite (Lourenço and Pham, 2010; Lourenço, 2012a, 2012b; Lourenço and Pham, 2012; Soleglad et al., 2012; Beron, 2015; Lourenço et al., 2018); strong troglomorphic features (Steiner, 2013); troglobitic element (Pham et al., 2017).
