Interpretive Summary: This paper describes a new genus, based on genomic and morphological analysis, for two species of Prominent Moths that had been misclassified. This work developed from analyses of genomic data that identified the problem and the need to describe a new genus, which we support with morphological data of adult specimens. This resolves one of the last remaining genus-level problems that followed the revision of the North American taxonomy. This work is of interest to entomologists, biogeographers, and evolutionary biologists.

Technical Abstract: We propose the name Millerocampa gen. n. in the Notodontidae (Heterocampinae) for two Central and South American species originally placed within the Cerurinae on the basis of reflective white scales and black zigzagging patterns on the forewing dorsum. Based on phylogenomic data and morphological analyses, we show that three names recently placed in the Heterocampinae genus Tecmessa form a morphologically and phylogenetically distinct heterocampine genus, Millerocampa gen. n., resulting in the following new combinations: Millerocampa gonema (Schaus), comb. n., type species of Millerocampa, and Millerocampa laqueata (Schaus), comb. n. The name Cerura olindata syn. n. is a synonym of M. gonema. Images of male and female adults, including all types, and genitalia of both recognized species of Millerocampa are presented.
