Material.

Lectotype (here designated) ♂: Chrysis aequinoctialis Spin. inédite D. Reiche, Bresil.

Catalogue Casolari & Casolari Moreno. Chrysis aequinottialis (sic!), 1, 34, 75, 1 (box 51).

Remarks.

Dahlbom (1854) described Chrysis aequinoctialis based on at least a series of specimens. In the Spinola collection, only a male of this species is currently housed. Bohart pinned a lectotype label under this specimen, but the lectotype designation has not been published. Kimsey and Bohart (1991: 425) placed Chrysis aequinoctialis in synonymy with Chrysis intricata Brullé, 1846 and reported "Syntype male, female; Brazil (Turin)". However, the female syntype is not preserved in the collection. Since the female is possibly lost and the above male of Chrysis aequinoctialis corresponds to Dahlbom’s species description, we here designate the male specimen as lectotype of Chrysis aequinoctialis . We deem Spinola’s collection as the right place for this lectotype designation, since the collection is cited in the original description and the choice of the male is to be preferred since the genitalia dissection can help in a future study of Chrysis aequinoctialis .

Chrysis aequinoctialis is currently considered as synonym of Chrysis intricata Brullé, 1846 ( Kimsey and Bohart 1991). Yet the interocellar distance measured between lateral ocelli (IOD), the length of the malar space and the transversal frontal carina (TFC) are distinctly different between the lectotype of Chrysis aequinoctialis and those specimens described by Bohart and Kimsey (1982: 135). It belongs to the smaragdula group and a worldwide revision this group is needed.

Current status.

Chrysis intricata Brullé, 1846 (synonymised by Kimsey and Bohart 1991: 425).
