Publisher's Synopsis
Excerpt from Journal of Hymenoptera Research, Vol. 16: October, 2007
Desirable as it might be to undertake a complete revision of the genus, this is at present not practicable. Rather than to get bogged down in a study which might never be completed and published, it is intended to publish a series of papers describing new species as well as review ing some known species. It is envisioned that a new key to species will complete the series.
