Homziak et al 2023 used molecular and ecological analyses to confirm the relationships within Catocala and between Catocala and Ulotrichopus . . .

Abstract
. . . . Here we reconstruct the first comprehensive molecular phylogeny for the genus based on 685 anchored hybrid enrichment loci sampled from 161 Catocala species (99 Nearctic, 62 Palearctic), four species of Ulotrichopus Wallengren and 33 outgroups. Phylogenetic analysis unambiguously recovers Catocala and Catocala + Ulotrichopus as monophyletic with strong support and resolves many backbone relationships within Catocala. . . . .
Phylogenetic analyses
Maximum likelihood trees of the concatenated nucleotide dataset (Figures1, S1, S2) and amino acid dataset (Figures S3, S4) recovered strong support for the monophyly of Catocala+Ulotrichopus (UFBoot/SH-aLRT=100/100; node 1), African Ulotrichopus (node 2) and Catocala (node 3; Figures1, 2). Similarly, ASTRAL analyses recovered strong support for the monophyly of Catocala+Ulotrichopus (LPP=1), African Ulotrichopus (LPP=1) and Catocala (LPP=1; Figures S5, S6). The nucleotide analysis placed the Asian U. macula as sister to Catocala with moderate support (UFBoot/SH-aLRT=88/91.4). This relationship was also recovered in the ASTRALanalysis but with low support (LPP=0.73), while the amino acid analysis placed U. macula as sister to the African Ulotrichopus clade with moderate support (UFBoot/SH-aLRT=89/94.6). We did not findsupport for a paraphyletic relationship between Catocala and Ulotrichopus as indicated by Mitter and Silverfine (1988) and Kühne (2005). Our results suggest that Catocala and African Ulotrichopus may be monophyletic sister taxa.
