Like members of the subtribe Coryciinae sensu stricto, Disperis is pollinated by oil collecting bees of the genus Rediviva.

Disperis has independently evolved a floral morphology much like that of Coryciinae s.s. in order to attract these pollinators.

Analysis of the nuclear ribosomal ITS first suggested the polyphyly of Coryciinae as Disperis did not branch with Corycium and Pterygodium.

[8] Moreover, Disperis appeared more closely related to Brownleea than to the subtribe Coryciinae, though this affinity did not receive strong statistical support.

[1] Brownleea and Disperis have a similar pollen structure and an upright labellum that lies over the front of the stigma.
