TAXONOMY

Led by the MLSG members VALTER WEIJOLA, ANDRÉ KOCH & MARK AULIYA


Here the number of monitor lizard species currently recognized are listed and allocated to their specific subgenera, followed by their describers and the year of description.

Species are taxonomically named in GENUS – SUBGENUS -SPECIES – (SUBSPECIES).

  • Currently 11 subgenera are recognized, some of which can be allocatted to species-groups (indicating very closely related species), however these groupings may change due to e.g., novel phylogenetic research.
  • At present 86 species and 18 subspecies (incl. the nomino-typic taxon) are subordinated to the GENUS Varanus described by MERREM in 1820. In contrast to the reptile database, where 85 species are listed, we list Varanus ornatus with reservations; more recent genetic studies remain to be seen.
  • For more recent publications on taxonomic and phylogenetic research > see on the right.
