Varanus bitatawa is the third species of  monitor lizard to be recognised by science that belongs to the "Pandan Biawak" group,  all of which are of at least as great a conservation concern as the Komodo dragon, but receive virtually none of the attention. Pandan Biawak occur only in lowland dipterocarp forest. The first species (Varanus olivaceus or Butaan) was discovered in 1845 and not seen alive by a scientist until the late 1970s. The next species (Varanus mabitang or Mabitang) was discovered in 2001 and in 2010 Varanus bitatawa (Butikaw or Bitatawa) was described. Other species of frugivorous monitor lizards may remain undescribed, but many may have  gone extinct without ever having been recognised.
