The intermediate gearbox is
- an epicyclic gearbox.
- a bevel gearbox.
- a reduction gearbox.
Explanation from PART66Online
The intermediate gearbox in a tail-rotor drive train uses bevel gears to turn the drive shaft through the angle change up the tail boom toward the tail-rotor gearbox. It is a direction-changing unit rather than an epicyclic reduction stage, which is the type used in the high-reduction main rotor gearbox.

I agree. It is a bevel gearbox. I have worked on aircraft with 1:1 ratio IGB's.
