Dendrochilum arachnites or wenzelii

[moria0672]

Watching "orchidspecies" I'm not sure about its right identification.
The plant is labeled as Dendrochilum arachnites but flower colour and size doesn't match (2 cm. in the site agaist 0.8 that I've measured, and colour red agains yellow) and coulour is very similar to Dendrochilum wenzelii (but leaves are very similar and there's no size on the site to compare it).
Could someone help me to have the right identification of this plant??
