Vidius felus O. Mielke, 1968 and Cobalopsis dorpa de Jong, 1983 are junior subjective synonyms of Vidius dagon (Evans, 1955) and Vidius catocala (Herrich-Schäffer, 1869), respectively

Genomic sequencing of the holotypes of Vidius felus O. Mielke, 1968 (type locality in Brazil: Minas Gerais) and Cobalopsis dorpa de Jong, 1983 (type locality in Suriname) and a syntype of Cobalus catocala Herrich-Schäffer, 1869 (type locality not specified) and three specimens from Brazil that we identified as Vidius dagon (Evans, 1955), comb. nov. (type locality Paraguay: Sapucay) (Fig. 7 blue), reveals two pairs of synonyms. COI barcodes of V. dagon, comb. nov. and V. felus and of V. catocala, comb. nov. and C. dorpa are 100% identical among the four specimens we sequenced in each group, but those between groups, i.e., of V. dagon, comb. nov. and V. catocala, comb. nov. differ by 6.2% (41 bp). Therefore, we propose that Vidius felus O. Mielke, 1968, syn. nov. is a junior subjective synonym of Vidius dagon (Evans, 1955) and Cobalopsis dorpa de Jong, 1983, syn. nov. is a junior subjective synonym of Vidius catocala (Herrich-Schäffer, 1869) .

To stabilize nomenclature and the synonymy proposed here, and to objectively define V. catocala with a single specimen, we designate its syntype that we sequenced, in the MFNB collection, bearing the following seven rectangular labels, 1 st purple, others white: [Origin.], [catocala], [Coll. H.—Sch], [Coll. | Staudinger], [Catocala | H-Sch.], [{QR code} http://coll.mfn-berlin.de/u/ | 44a010], and [DNA sample ID: | NVG-15036G03 | c/o Nick V. Grishin] as the lectotype of Cobalus catocala Herrich-Schäffer, 1869 . This specimen is in poor condition, lacking abdomen and antennae, wings and the head appear to be glued to the thorax, all wings have tear and, except the right forewing, are missing some pieces. However, whole genome shotgun dataset obtained from the lectotype is of a good quality for a specimen of this age and unambiguously defines this name, e.g., its COI barcode is 100% identical to the holotype of C. dorpa suggesting no errors in either sequence.
