Aldabrachelys[1] is the recognised genus for the Seychelles and Madagascan radiations of giant tortoises, including the Aldabra giant tortoise (Aldabrachelys gigantea).


This name is problematic in that the type specimen is actually represents Chelonoidis denticulata;[2] however, this was discussed and petitioned before the ICZN[3] and accepted: the name Aldabrachelys is therefore the correct name for this genus.


A. g. arnoldi – Arnold's giant tortoise
A. g. daudinii – Daudin's giant tortoise (extinct)
A. g. gigantea – Aldabra giant tortoise
A. g. hololissa – Seychelles giant tortoise

Tortoise remains from over 1,000 years ago, which have been found on the Comoros, are believed to have been from an unknown species of the same genus.[4]
