Scorpion, for example, found in parts of Iran and Chad (8)
I believe the answer is:
arachnid
'scorpion for example' is the definition.
(scorpion is a kind of arachnid)
'parts of iran and chad' is the wordplay.
'parts of' indicates anagramming the letters.
'and' is a charade indicator (letters next to each other).
'iran'+'chad'='iranchad'
'iranchad' is an anagram of 'ARACHNID'.
'found in' acts as a link.
(Other definitions for arachnid that I've seen before include "web designer" , "Spider or scorpion, e.g." , "Spider in a chard" , "Animal class including spider, scorpion etc" , "Group including spiders and scorpions" .)
