Proboscis

A proboscis was an organ on insects' heads where a human or Time Lord had a nose.

Among others, the beetle-like Attendant, (PROSE: The Secret in Vault 13) Zarbi (PROSE: Doctor Who and the Zarbi) and Wirrn (PROSE: Placebo Effect) had proboscises.

Her Royal Tectrope, ruler of the Tymerian Empire, jammed her fourth proboscis in a suction door, afterwards outlawing all doors, which caused the empire's fall. (PROSE: Forever Autumn)

Jason Clearfield experimented with creating giant insects as hosts for the minds of Wyrresters. The mosquitoes he made had scopolamine in their proboscis to control the local villagers. (PROSE: The Crawling Terror)
