Remarks.

In the Spinola collection, two specimens from Egypt (D. Waltl) and South Africa (Cap B. [onne] Esp. [ érance]" (D. Klug)) referring to this species are present. Only one specimen belongs to the original type series. However, it is currently impossible to state which one, since both specimens lack locality labels. At present, we cannot identify the specimen that had been collected in Egypt. Both specimens were examined by Dahlbom (1854: 60) and they are found under the name " Hedychrum coelestinum Kl.", a species never described by Klug. Dahlbom (1854) erroneusly assigned this species to Klug and not to Spinola, even though he knew Spinola’s (1838) paper. Furthermore, Dahlbom (1854) named this species " caelestinum ", which we consider an incorrect subsequent spelling ( Madl and Rosa 2012: 96). The two specimens were labelled as lectotype and paralectotype by L.D. French, but the lectotype designation has not been published. The two females have different colours: one is greenish and the second is a deep blue. The blue one was labelled by French as paralectotype, but the colour matches Spinola’s description ("La couleur du corps est d’un bleu plus intense") and we suppose that this one could be the type. In Dahlbom’s collection in LZM, there is another specimen labelled as type by a former curator, not by Dahlbom himself, and that refers to the specimen listed as " caelestinum Kl." ( Dahlbom 1854: 60).
