New species, records, and a synonymy of African Sisyridae (Neuroptera Author Oliver S.

Esben-Petersen (1915) described a species of Sisyra from various localities in Sudan that he believed to be the European S. terminalis Curtis. Much later Tjeder recognized these were not the true S. terminalis , and gave the name S. nilotica to the Sudanese material, and designated a male from Lake Ambadj (Bahr el Ghazal) as the type . He apparently did not have any examples in front of him as he gave no further description or figures, as almost certainly he would have had he actually seen any material. The type material of S. nilotica was supposedly in the collection of the Museum Koenig, Bonn, Germany . In an attempt to obtain examples so that the species could be illustrated in more detail, I contacted authorities at this museum. Dr. Netta Dorchin, the curator in charge, was unable to locate any examples in their collection. She also wrote colleagues in Denmark and Sweden (where Esben- Petersen and Tjeder worked, respectively), with no positive results. I must assume, unfortunately, that the type series is lost, and the species will remain a species inquirenda , at least until new material is found from these regions in Sudan .
