Notes.

Morphological as well as phylogenetic analyses, based on nrITS and nrLSU sequence data of the specimens PREM61214, PREM61216, PREM61218, PREM61219, PREM61862 and PREM61875 collected from V. natalitia and V. permixta , respectively, supported conspecificity and their placement in R. macowaniana . Therefore, we report V. natalitia and V. permixta as new hosts for R. macowaniana .
