Remarks.

Spinola (1840: 202) gave the diagnosis of a male belonging to Chrysis fasciata Fabricius, 1804 (nec Olivier, 1790), collected at Cayenna in French Guyana by Leprieur and received via Buquet. In the same diagnosis, Spinola (1840: 203) described Chrysis intricans Spinola, 1840 ("n. sp.?", giving a complete description), based on a second specimen: "Celle-ci ne fait pas partie des récoltes de M. Leprieur, et elle est étrangère au sujet de ce Mémoire; je me contenterai d’en constater l’existance, et de signaler les traits qui la distinguent de notre n°50". Therefore, there should be theoretically both a specimen of Chrysis fasciata Fabricius sensu Spinola as well as a holotype of Chrysis intricans Spinola in the Spinola collection.

Dahlbom (1854: 211) described Chrysis distinctissima based on one specimen examined in 1847 at LZM and on a second specimen loaned by Spinola under the name Chrysis intricans . He considered as Chrysis distinctissima also Chrysis fasciata Spinola (nec Fabricius). In particular, Dahlbom listed in the type series: " Chrysis fasciata Spinol. Annal. Ent. 1840. 202: 50"; then the specimen from Lund; lastly the specimen known as Chrysis intricans " Mus. Spinolae", without further remarks. Two pages after, Dahlbom (1854: 213) listed under the name Chrysis coerulans Fabricius a second specimen from the Spinola collection named Chrysis intricans collected at Cayenne and received by Buquet. This specimen should correspond to the holotype of Chrysis fasciata Spinola (nec Fabricius). The Spinola collection does not house any sample labelled " Chrysis intricans ", but it houses two specimens label " Chrysis distinctissima Dlbm - Chrysis fasciata m.[ihi]". The first is severly damaged, having no metasoma. The second is in good condition. The first was labelled by Bohart as holotype of Chrysis intricans and lectotype of Chrysis distinctissima ; the second specimen was labelled by Bohart as Chrysis excavata Brullé, 1846. The lectotype designation of Chrysis distinctissima has not been published. In Dahlbom’s collection in LZM, there are no labels referring to Chrysis distinctissima Dahlbom and there is only one specimen lablled Chrysis fasciata Fabricius. Unfortunately, we currently cannot confidently infer which specimen could be the type of one species and which one could be the type of the second species, since Spinola’s descriptions are ambiguous. According to Kimsey and Boahrt (1991) it belongs to the Chrysis intricans group.
