Searching through materials at the Natural History Museum in Paris, Simon van Noort recently came across a long-neglected field box of wasp specimens. Collected 80 years earlier by André Seyrig in Madagascar, the box contained several specimens of wasp in the Paramblynotus genus. The big surprise: wasps in this genus had never before been seen in Madagascar.

"Discovering the field box full of unusual wasps was reminiscent of excitement around opening presents as a child," says can Noort with the Natural History Department, Iziko South African Museum. "There is a huge diversity of undiscovered species in Africa and Madagascar and every new sample contains species unknown to science. [André] Seyrig was a prolific collector of wasps. It was a privilege to be able to work on some of his specimens that had not been examined by specialist taxonomists since they were collected in the 1930's."

The discovery of the field box has led to the description of two new species of wasp for Madagascar, including one named after Seyrig, and the first ever wasps in this genus for the island-country. A recent paper in the open-access Journal of Hymenoptera Research describes these new Malagasy species, as well as six other new Paramblynotus wasps.

Found only in tropical Africa, Paramblynotus wasps are tiny, but look something like gall wasps. Researchers believe that the wasps are parasites of wood-boring beetle larvae, but that has yet to be confirmed.
