Classification

The morphology of Andalucia broadly resembles that of other jakobids. Molecular data has not always been conclusive, but recent phylogenomic analyses indicate that Andalucia is a sister group to the other jakobids, in other words more closely related to them than to the Heterolobosea or Euglenozoa (the other two groups in the Discoba).[2] The α-tubulin gene of Andalucia more closely resembles that of opisthokonts and diplomonads than its closer relatives, the apparent result of horizontal gene transfer.[3]

Species

As of 2009, the genus contains two species:[1][3]

  • A. incarcerata was until 2006 known as Jakoba incarcerata. It lives in sulfide-rich sediments, especially marine intertidal ones.[3] Currently it is the type species of the genus Stygiella Pánek, Táborský & Čepička 2015.[4]
  • A. godoyi is a soil heterotroph.

Analysis of DNA sequences from the environment suggest at least two additional species which have not been isolated or formally described.[3]
