ABSTRACT
We describe a new species of satyrine butterfly, Ypthima thao Monastyrskii Lang sp. nov., recently discovered in northern Vietnam and southwestern China. This species is similar to Y. praenubila, which is distributed in the same region, and we speculate on their biogeographic origins.

A new species and eight new subspecies of Papilionoidea discovered in Vietnam between 2002 and 2020 are described and illustrated. The status of two taxa are revised. New taxa include Pieridae: Delias sanaca bidoupa Monastyrskii Vu subspec. nov. and Talbotia naganum aurelia Monastyrskii Vu subspec. nov.; Nymphalidae: Abrota ganga pulcheria Monastyrskii Vu, subspec. nov.; Bassarona recta consonensis Monastyrskii Vu, subspec. nov.; Pantoporia bieti aurantina Monastyrskii To subspec. nov.; Ragadia latifasciata cristata Monastyrskii Vu, subspec. nov.; Ragadia latifasciata crystallina Monastyrskii Vu, subspec. nov.; Faunis indistincta luctus Monastyrskii Vu subspec. nov. Aemona gialaica Monastyrskii, K. Saito Vu, spec. nov. The taxon infuscata Devyatkin Monastyrskii, previously described as the subspecies Aemona tonkinensis infuscata, was elevated to the species level, while the taxon critias (Ragadia critias Riley Godfrey) was reduced to a subspecies. Three Satyrinae species were recorded from Vietnam for the first time: Palaeonympha opalina Butler, 1871; Ypthima motschulskyi Bremer Grey, 1853; and Ragadia latifasciata Leech, 1891.

The Graphium (Pazala) mandarinus group was recently defined and the status of taxa as well as the number of species was revised. We report here the discovery of a new species from Kon Tum plateau of the Truong Son (Annamite) Range of Central Vietnam, which we describe based on morphological and molecular evidence. Molecular phylogeny shows that the new taxon, G. (P.) wenlingae Hu, Cotton Monastyrskii sp. nov., is sister to G. (P.) daiyuanae Hu, Zhang Cotton, 2018 plus G. (P.) confucius Hu, Duan Cotton, 2018. Molecular dating analysis further suggests that this new species diverged from its sister clade in the Pliocene (~3.5 million years ago). The new taxon constitutes the eighth and southernmost species of the mandarinus group.

The Lethe manzorum-group is studied and two new species (L. sisii sp. nov. and L. giancbozanoi sp. nov.) closely related to L. manzorum (Poujade, 1884) from China are described and illustrated.
