Andrianavoay baroni
(Newton, 1893)

The type species, A. baroni, was originally named "Steneosaurus" baroni by ET Newton in 1893 on the basis of a partial skull listed as "NHMUK PV R 1999",[2] and an associated osteoderm from Andranosamonta, Madagascar.[2] In her unpublished 2019 thesis, Michela Johnson coined the nomen (ex dissertatione) Andrianavoay for S. baroni.[3] The genus name was published in 2020.[1]
