Distribution.

Indonesia (Sulawesi).

Etymology.

The specific name is derived from Sulawesi, the type locality.

Biological note.

Host unknown. Female wasps were, as a whole, caught in Malaise traps except for one individual caught by sweep net, whilst male wasps were caught exclusively by sweep net. On 2nd March, many male wasps were flying around one (unidentified) shrub growing between 500 and 800m.
