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 .
