Sphex ignita Linnaeus, 1758 (currently Chrysis ignita) has a unique record.
As far as I know, it's the only species with 3 lectotypes.
At Burlington House, four specimens are found under the name Sphex ignita.
One is bearing the lectotype labels of Blüthgen and Linsenmaier, while a third lectotype designation was given by Bohart.
Blüthgen (1959: 14) and Linsenmaier (1959a: 156) contemporary designated the lectotype of ignita. According to Day (1979: 65) neither appears to have examined the specimen himself. Both authors designated the lectotype based on the information provided by Yarrow.
Bohart (in Kimsey & Bohart, 1991: 420) designated again an other lectotype. However there are no labels by Bohart under the specimens found in the collection and I do not consider valid this designation.
Pictures of the types and other specimens in the Linnean collection can be found here

Since Yarrow selected the same specimen for the lectotype designation of Blüthgen and Linsenmaier, there's no doubt on which is the lectotype.
However, I don't know who should be considered as the first revisor.
Linsenmaier published the lectotype designation on July 31, 1959.
I don't know when Blüthgen published his designation in 1959, therefore I don't know which one has the priority.
Blüthgen published his article here:
Mitteilungen der Deutschen Entomologischen Gesellschaft, 1959, vol. 18 (6).
Does anyone know when this issue was published?
Many thanks,
