You can try a simple way: search for the -, then the : and the word after that is captured.

[^-] -[^:] :\s*([^\s] )

[^-] finds characters which are not the -
- finds the - after
[^:] finds characters which are not the :
: finds the : after
\s* makes us ignore white-space
([^\s] ) finds the word as "everything but white-space"

You can play around with it here:
