Etymology
The specific epithet ‘gotamiae’ is in honour of Gotami, Gautama Buddha’s foster mother and the first woman to be ordained a nun or bhikkhuni in the Buddhist monastic order. The name is treated as a noun in the genitive case.
Diagnosis
This species is diagnosed by the presence of a triangular metascutellum which extends over the horn on T1.
