Chrysis (Trichrysis) scyphiphora Linsenmaier, 1984: 223 . Holotype ♀; Brazil: Santa Catarina (NMLU, examined). Synonym of

Caenochrysis parvula ( Fabricius, 1804) according to Kimsey & Bohart (1991: 304); Lucena et al. 2024: 20. Caenochrysis scyphiphora ( Linsenmaier, 1984) : present paper: stat. resurr.

Material examined. Holotype of Chrysis scyphiphora , ♀: Brasilien, Nova Teutonia 27°11’B–52°23’L Fritz Plaumann I.1960 300-500m / ♀ Type Chrysis L. scyphiphora Lins. Linsenmaier det. 1973 / NML_ENT GBIF_ Chr0041389 ( NMLU). Allotype: ♂: Brasilien, Nova Teutonia 27°11’B–52°23’L Fritz Plaumann 6.X.1960 300- 500m / NML_ENT GBIF_Chr0041390 ( NMLU).

Chrysis scyphiphora Linsenmaier, 1984 was synonymized with Caenochrysis parvula ( Fabricius, 1804) together with Chr. chrysofacialis and Chr. turmalina by Kimsey & Bohart (1991).

Caenochrysis scyphiphora can be differentiated from Cae. parvula by the coarse punctation on the mesosoma ( Fig. 2B ); the metasomal sculpture with wide interspaces ( Fig. 2E ); the second tergum fully punctate, with sparse punctures on the posterior half ( Fig. 2E ); the apical margin of the third tergum rounded laterally ( Fig. 2E ); whereas in Cae. parvula the punctation on the mesosoma is relatively dense and uniform ( Fig. 2A ); the first tergum is fully punctate ( Fig. 2D ); the second tergum has a wide, impunctate longitudinal median stripe ( Fig. 2D ); and the apical margin of the third tergum is distinctly tridentate, with two small, acute lateral angles ( Fig. 2D ).

Caenochrysis scyphiphora can be differentiated from Cae. turmalina by the coarse punctation on the mesosoma ( Fig. 2B ) and the elongate black spots on the second sternum ( Fig. 2H ), whereas in Cae. turmalina the mesosomal punctures are small and sparse ( Fig. 2C ) and the black spots on the second sternum are ovoid and apically convergent ( Fig. 2I ).

Pending a revision of all of the species synonymized with Cae. parvula , based on the different sculpture, shape of the apical margin of the third tergum and of the black spots on the second sternum, we consider Caenochrysis scyphiphora ( Linsenmaier, 1984) stat. resurr. a valid species.
