Remarks.

Dahlbom (1854) described three variations (a, b, c) of Chrysis alternans . Bohart (in Kimsey and Bohart 1991: 381) designated a lectotype of Chrysis alternans at ZMUC. Dahlbom’s three variations of Chrysis alternans are nowadays considered distinct species, referring to two different species groups. In Spinola’s box 51, there are three specimens placed under the label Chrysis alternans ( Casolari and Casolari Moreno 1980: 79). Two of them belong to var. a, whereas the third refers to var. b and belongs to a different species with a similar colouration. A further specimen of " Chrysis alternans " was found in box 52, under the name Poecilochroa alternans and should be considered as another paralectotype referring to var. b. The examination of the lectotype in ZMUC revealed that it belongs to var. a ( Madl and Rosa 2012: 16). It belongs to the alternans group.
