The mystifying lip

Found this small Phalaenopsis growing plentifully on trees just beside a stream which used to be clear but now has turned dirty brown due to construction and erosion upstream.
Not totally sure what species it is - Phalaenopsis lamelligera ? Perhaps pantherina...or even a spotted cornu-cervi. I decided to zoom in on the complicated lip to assist identification. In orchids, the lip is usually the landing pad for insect pollinators. I wonder what the 2 small hair-like appendages are for - tickle the pollinator ? And what about the erect structure with narrow via like the eye of a needle ? Quite baffling.

Hopefully, an expert can come along and throw some light on this.
