I knew I'd heard the word before, in the distant past:

Main Entry: fren·u·lum
Pronunciation: 'fren-y&-l&m
Function: noun
Inflected Form(s): plural fren·u·la
Etymology: New Latin, diminutive of Latin frenum
1 : a connecting fold of membrane serving to support or restrain a part (as
the tongue)
2 : a bristle or group of bristles on the front edge of the posterior wings
of some lepidoptera that unites the wings by interlocking with the
retinaculum of the forewings
