South American dictators, not a model of industry, are lecherous types (6)
I believe the answer is:
satyrs
'lecherous types' is the definition.
(lecherous creatures in Greek myth)
'south american dictators not a model of industry' is the wordplay.
'south american' becomes 'SA'.
'dictators' becomes 'tyrants' (tyrant is a kind of dictator).
'not' indicates named letters should be taken away.
'a model of industry' becomes 'ant' (ants are hard-working or industrious).
'tyrants' with 'ant' removed is 'tyrs'.
'sa'+'tyrs'='SATYRS'
'are' acts as a link.
(Other definitions for satyrs that I've seen before include "Mythical woodland gods half-man and half-goat" , "Greek gods of woodlands" , "Woodland deities who attended Bacchus" , "goat-like characters" , "Woodland gods, part men and part goats" .)
