However, I just finished a study which found 8-10 apparently new species of
unrelated invertebrates which live in hollow stems and have never been
collected although their home range has been collected for 150 years (Sri
Lanka).  They apparently don't venture out of the stems much.  Using the
English language, I suggest these are cryptic species.  It does get
confusing, because the lizards noted above do not seem to be sub-, sister,
or sibling.
