Taxonomy

The status of R. interrupta in relation to R. parva is still a point of discussion. Based on research of Wigham, R. interrupta is considered by many authors as a variety of form of R. parva. Nordsieck and Verduin think however that R. interrupta and R. parva are two different species. Both species have a sympatric appearance.
