ETYMOLOGY. The specific epithet honours Kasetsart University, the institution that provided a grant under the program “KU Reinventing” for this research. Moreover, the type specimen was collected on 2nd February 2022 which coincides with the 79th anniversary of the founding of Kasetsart University. We would like to express our sincerest gratitude to our beloved Kasetsart University and also to all the teachers who kindly taught, encouraged and supported us.
