Not quite... actually, most of the Schomburgkias got classified as Laelia (superbiens, moyobambae, splendida, lueddemannii, and a bunch of others). These have slender, solid pseudobulbs. The ones classified as Myrmecophila have more stout pseudobulbs that are hollow. (the pseudobulbs actually look superficially a lot like Den. speciosum). The most common of these in cultivation is Myrmecophila tibicinis. All of the (former) Schomburgkias have wavy petals and sepals. But the lip of the two groups is quite different. The lip in the photo definitely looks like Myrmecophila, so that is where OP should look to try to get a match.
