Etymology

The species is named after the common tropical reddish soil type laterite, on which the species was collected.

Condition of type material

In the holotype, the proximal margin of the gvc is slightly deformed but condition still allows precise descriptions. The flagellomeres are deformed, thus the width specifications are not precise. The left hind leg is missing (except coxa). Both fore wings and the right hind wing are detached. The metasoma is slightly deformed and detached, thus the body length measurement is not precise.
