Dictatorships are dangerous because Hitler’s regime was dangerous.
The subjects are different and the predicates are the same, so the argument form is beta (a is X because b is X): “Dictatorships (a) are dangerous (X) because Hitler’s regime (b) was dangerous (X)”.
The conclusion is a universal statement (u) and the premise is a singular statement (s), so the argument substance is ‘us’: “Dictatorships are dangerous (u) because Hitler’s regime was dangerous (s)”.
The keyword EXAMPLE describes the relationship between subjects a and b. The argument lever can thus be formulated as “Hitler’s regime (b) is an EXAMPLE of dictatorship (a)” or “Dictatorships (a) are EXEMPLIFIED by Hitler’s regime (b)”.

Notes
Apart from beta form arguments with substance ‘us’, those with substance ‘up’ or ‘ps’ also fit the scheme, as the scope of the conclusion is broader than that of the premise.
A beta form argument with substance ‘us’, ‘up’, or ‘ps’ that has statements of fact (F) as its conclusion and premise can also be called an ‘argument from species’.
