Chrysis distinctissima Dahlbom, 1854

Chrysis distinctissima Dahlbom, 1854

Chrysis distinctissima Dahlbom, 1854: 211 . Syntypes; “America meridionali” (type depository unknown).

Material examined. 1♀: Obidos 18.1.1904 Ducke / Brazil Estado do Pará / Chrysis ♀ distinctissima Dlb. <handwritten by Ducke> / ex Coll. Gribodo Brasile Pará A. Ducke ( MSNG); 1♂: Obidos 22.12.1904 Ducke / Brazil Estado do Pará / Chrysis ♂ distinctissima Dlb. <handwritten by Ducke> / ex Coll. Gribodo Brasile Pará A. Ducke ( MSNG); 1♀: distinctissima det. Mocsáry ( HNHM); 1♀, Suriname Paramaribo V.1958 P.H. v. Doesburg Jr. / Chrysis L. distinctissima Dhlb. Linsenmaier det. 60 ( NMLU).

Mocsáry and Linsenmaier’s concept of Chrysis distinctissima differs from Ducke’s, as the specimens they examined are closely related to or even conspecific with Chr. excavata Brullé, 1846 . Kimsey & Bohart (1991: 405) reported MRSN as the depository of the type series of Chr. distinctissima , but Rosa & Xu (2015) noted that the types and depositories are unclear. In Spinola’s collection at MRSN, two possible syntypes exist, one of which, severely damaged and lacking the metasoma, was selected by Bohart as the lectotype, although its designation was never published. Bohart identified the second specimen as Chr. excavata . Considering that the descriptions provided by Spinola (1840) and Dahlbom (1854) are ambiguous, and that the specimen selected by Bohart as lectotype lacks the metasoma, which bears diagnostic characters such as the teeth shape on the apical margin and the sternal black spots, the designation of a neotype after further research should be considered to properly establish the species concept for this taxon.
