discussion
Normally considered part of the R. tumida complex, but recent molecular studies based on mtDNA and using nDNA markers found that this species and R. mira form a sister clade to the tumida complex; this similarity between R. parvula and R. mira was also observed in external and skull morphology. Two subspecies recognized.
