Need help identifying orchid from Sulawesi

[euplusia]

We have this orchid in a friend's nursery since decades. The tag says Sulawesi, former Celebes, Indonesia. It flowers here in November. 1-3 spikes with multiple small flowers emanate from the leaf axils of the lower leaves on the last mature pseudobulb. Each flower measures 5mm. They last a few days. I don't even have a clue of the tribe or genus.
I know that here is the place to find some crafty clever experts. Please tell me what it is, or where i can direct my search to.

Pretty sure that's an Eria, look at section Urostachya (multiflora, floribunda, pachystachya, etc.). To return all the IOSPE records in that section w/out navigating through the site, do a google search like "site orchidspecies.com: eria urostachya", minus the quotes. I'm not sure how accurate their IDs are and I don't know any other online sources of info on this genus, but I'm at my parents' house this weekend so if I have time I'll see if my Dad has any relevant books in his library.

Wow, great. Must be an Eria/Pinalia. Thank you very much, gnathaniel. I'll do a deeper search later.
