Chrysis (Trichrysis) invisa Linsenmaier, 1984: 210 . Holotype ♀; Argentina: Tucuman (NMLU, examined). Synonym of

Caenochrysis armata ( Mocsáry, 1889) according to Kimsey & Bohart (1991: 301); Lucena et al. (2024: 16). Caenochrysis invisa ( Linsenmaier, 1984) : present paper: stat. resurr.

Material examined. Holotype of Chrysis invisa , ♀: Argentinien I.53 S.P. Colalao Tucuman Coll. Linsenmaier / NML_ENT GBIF_Chr0041155 ( NMLU) . Paratypes: 2♀♀: same data / NML_ENT GBIF_Chr0041152-41153 ( NMLU) ; 1♀: Argentina: Tuc. Horco Molle, c. 12km. W of Tucuman. 700m 17.III.1974 C.R.

Both Chrysis invisa Linsenmaier, 1984 and Chr. aptata Linsenmaier, 1984 were synonymized with Caenochrysis armata ( Mocsáry, 1889) . However, Linsenmaier’s (1984) description of Cae. invisa and its type material does not match the description of Cae. armata , nor specimens identified as Cae. armata by Ducke and deposited at European collections. In particular, compared to the diagnosis of Cae. armata given above under Cae. aptata , Cae. invisa has the first flagellomere 1.4 × as long as the second ( Fig. 1D ); the transverse frontal carina is weak, concolorous with the rest of the head, and irregularly arched with two short, barely visible branches ( Fig. 1D ); the metasoma is uniformly green to blue, with a narrow dark black stripe at the base of the first and second terga ( Fig. 1E ); the metasomal punctation is dense and uniform, with small punctures covering the entire tergum ( Fig. 1E ). Caenochrysis invisa can also be distinguished from Cae. aptata as detailed above under Cae. aptata . Based on these characters, we consider Caenochrysis invisa ( Linsenmaier, 1984) stat. resurr. a valid species.
