Yes, Aerfer Ariete is the correct answer.
The plane is a distant relative of Ambrosini SAI.207 posted earlier in this thread. The first stage in its development was fitting a jet engine onto a SAI.7 airframe (which, itself, was a two-seat trainer developed from SAI.207 via its improved variant SAI.403). The resulting Ambrosini Sagittario was then further developed, and end of the line was the Aerfer Ariete.
