The genus Pangora Moore (1879) is endemic to south Asia, with four known species distributed in India, Sri Lanka, and Nepal. The current study offers the scientific community the first mitochondrial genome sequence of the known species Pangora matherana (Moore). The phenotypic and phylogenetic tree analysis reveals a new species, Pangora keralaensis Abhilash & Adarsh sp. nov., from India. The male genitalia and morphological analysis of the new taxa are also provided. A preliminary phylogenetic tree based on the mt COI DNA sequence is also provided for the new species and the known species, Pangora matherana (Moore, 1879).

In this study, we reassess the phylogenetic relationships of the genus Sesamia Guenée, 1852 and examine in more detail the members of the nonagrioides species group, for which three distinct species complexes are identified. The calamistis subgroup comprises eight species, of which four new species are described: Sesamia kabirara Le Ru sp. nov., Sesamia kalale Le Ru sp. nov., Sesamia mapalense Le Ru sp. nov. and Sesamia teke Le Ru sp. nov. The incerta subgroup consists of 11 species, of which four new species are described: Sesamia kamba Le Ru sp. nov., Sesamia lalaci Le Ru sp. nov., Sesamia lusese Le Ru sp. nov. and Sesamia msowero Le Ru sp. nov. The nonagrioides subgroup comprises ten species of which two new species are described: Sesamia libode Le Ru sp. nov. and Sesamia satauensis Le Ru sp. nov. Phylogenetic and molecular species delimitation analyses of a multi-marker molecular dataset allow us to investigate and clarify the status of Sesamia species and species complexes. Our results yield a well-supported phylogenetic hypothesis for the genus, which supports the monophyletic nature of all but one species subgroup. The results of 16 distinct molecular species delimitation analyses show some levels of incongruence and, overall, a tendency towards over-splitting. We also present an updated list of species for the genus Sesamia and provide morphological keys based on male and female genitalia to determine the species group of any Sesamia species and to identify all species belonging to the nonagrioides species group.

We analyzed COI barcode sequences from 138 over-a-century old specimens of Calinaga including 36 name-bearing type specimens stored at the Natural History Museum London. These new data, combined with previously available RPS5 sequences, divide the Calinaga samples into four well-supported mitochondrial lineages that together with a novel wing-pattern analysis, support the recognition of six species (lhatso, buddha, brahma, aborica, formosana and davidis), with all other names subsumed either as subspecies or synonyms. One new taxon is described, Calinaga aborica naima Vane-Wright, ssp. n.
