The growth habit of that plant you posted is very Myrmecophilia like. They have 1, 2 or 3 leathery leaves. Pseudobulbs are broadest at the base and gradually get thinner or tapered at the apex. Many of them have a low growing growth habit which make them natural contenders for either mounted or basket culture.
I believe that the Schomburgkia genus is now the group of species that grow more upright, thicker, yet tapered pseudobulbs with the same, but larger 1-3 leathery leaves. And these species have the hollow pseudobulbs which are often inhabited by ants. Their flowers are densely clustered at the end of a long inflorescence. The smaller Myrmecophilia have the flowers spread out a bit more on a shorter inflorescence.
