Since the holotype was collected in 1978 there have been no reports of this species and if it still exists then it has a very low population. The IUCN categorise it as Critically Endangered (Possibly Extinct).
This species reaches a length of 9cm (04inches).
The specific name honours Donn Eric Rosen (1929-1986) of the American Museum of Natural History.[1]
