Diagnosis (genus): Worm-like gymnophthalmids, with body and tail cylindrical, elongate, and rudimentary limbs that may bear from zero to four clawed or clawless digits. Ear-opening absent. Lower eyelid with undivided semitransparent disc. Fronto-parietals absent, prefrontals, supraoculars, and interparietal present or absent. Dorsals and ventrals mostly in continuous transverse rows. Dorsals keeled or smooth, ventrals smooth (from Avila-Pires 1995: 342).

|Comment||Type species: Chalcides dorbignyi DUMÉRIL & BIBRON 1839 is the type species of the genus Bachia GRAY 184 (see Dixon 1973: 14). Bachia is the type genus of the tribus Bachini (Castoe et al. 2004) or the subfamily Bachiinae (Colli et al. 2015, Pyron et al. 2013). Murphy et al. 2019 erroneously gave the type species of Bachia as Chalcides flavescens BONNATERRE 1789.|
