Notes.

Dahlbom (1845) described Chrysura sulcata based few specimens from Rhodes " Chrysura sulcata nob. Rhodus rar. Hedenborg. ". Since Dahlbom wrote " rar. " and not " rariss. " he examined at least two specimens. The original diagnosis ( Dahlbom 1845) is quite different from the description given in 1854 and the current interpretation of the species. Dahlbom (1845) described sulcata as a species with red sternites " Divis. 2. Abdominis dorsum totum aureum. Venter igneus ", whereas the species today identified as Chrysura sulcata has blue or blue-green sternites, which is a useful characteristic to separate it from Chrysura rufiventris Dahlbom, 1854 in south Europe. Moreover, he described Chrysura sulcata with green mesosoma (" Thorax viridis "), whereas all the specimens studied have blue mesosoma, with green reflections on the lateral sides of the mesonotum.

In the general collection, under the name Chrysura sulcata , two specimens were found. These are a specimen of Chrysura sulcata and a second specimen (without head), which belongs to Chrysis aestiva Dahlbom, 1845, also described from Rhodes. It bears the same labels: [Rhodes] [Hedb.]. This specimen is obviously different, since it has two small teeth along the anal margin; but we noticed that the position of the ovipositor somehow hides the two small teeth. Perhaps it is possible that Dahlbom did not see these two small teeth and considered this specimen as a syntype. The latter has red sternites and green mesosoma.

Later Dahlbom (1854: 116), after the examination of a Sicilian specimen housed at the NHMW, gave a better and detailed description of the species, which was accepted by all the following authors and is currently recognised. The specimen examined at the NHMW is lost and was considered as a syntype by Kimsey and Bohart (1991). Since the original description is ambiguous and the species could be described from several specimens, in accordance with the ICZN (Art. 73) we hereby designate the lectotype of Chrysura sulcata on the male specimen bearing the label [Type] and characterised by the broken last tergite (Plate 26D). The designated lectotype matches the current interpretation of the species given by Dahlbom (1854) and Linsenmaier (1959).
