Type locality: montagne d’Ambre
|Types||Holotype: MNHN-RA 1893.0207 (holotype by monotypy)|
|Diagnosis||Diagnosis (genus): The genus Paracontias as currently conceived (Brygoo, 1980b) has the following derived character states: supranasals absent; prefrontals absent; pretemporal single; nasal greatly reduced; loreal single (P. holomelas may occasionally have two); preocular single; presubocular single; supralabials five, third subocular; postsupralabial single; infralabials contacted by postmental one; external ear opening absent; limbs absent without external trace of their former position; presacral vertebrae >= 46; sternal ribs <= 2; mesosternum absent; complete inscriptional chevrons >= 19.|
An interesting retained primitive character in Paracontias, especially vis-aÁ -vis many Amphiglossus, including the strongly limb-reduced A. stylus, is the contact between the first supraocular and the frontonasal which thereby excludes the first supraciliary from contacting the frontal.
Three subgenera have been recognized within Paracontias: Angelias (Brygoo, 1980b), Malacontias (Greer, 1970) and Paracontias (Mocquard, 1894). We have not used these taxonomic groups because the two characters used to diagnose them as subgenera ± the position of the nasal opening in relationship to the rostral scale and first supralabial scale, and the number of presacral vertebrae ± do not result in monophyletic groups in all cases. Angelias (two species) is diagnosed on the basis of the primitive state in each character; Paracontias (one species) has as its only derived character the highest number of presacral vertebrae, and Malacontias (two species) is diagnosed on a derived scale arrangement and an intermediate number of presacral vertebrae. Hence only Malacontias or a group combining Malacontias + Paracontias (intermediate to high number of presacral vertebrae) is likely to be a true lineage on these characters (Andreone et al. 2002: 164).
|Comment||Limb morphology: Limbless; |

Type Species: Paracontias brocchii MOCQUARD 1894 is the type species of the genus Paracontias MOCQUARD 1894.
Key: Andreone et al. 2002: 164 provided a key to the species of Paracontias.
|Etymology||Probably named after Paul Louis Antoine Brocchi (1838-1898), a herpetologist who worked at the Museum National d'Histoire Naturelle, Paris, with Milne-Edwards (Mocquard didn’t explain the name but Brocchi is the most likely candidate).|
