Contribution to the knowledge of the genus Barsine Walker, 1854 from Xizang, China with description of a new species (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

New information of the genus Barsine Walker, 1854 from Xizang Autonomous Prefecture, China is provided. A new species related to Barsine defecta Walker, 1854, B. gratissima (de Joannis, 1930), B. germana (Rothschild, 1913) and B. kirata Volynkin N. Singh, 2020 is described from Chayu County of Southeastern Xizang: Barsine mahakala S.-Y. Huang Volynkin sp. n. Barsine germana (Rothschild, 1913) and B. atypicobarsine N. Singh, Kirti Joshi, 2016 are newly recorded from China, with the female of the latter described and illustrated for the first time. Adults and genitalia of the aforementioned taxa are illustrated.

Processuridia, a new genus for two new species from China and Indochina (Lepidoptera: Erebidae: Arctiinae: Lithosiini).

A new Nudariina genus, Processuridia S.-Y. Huang Volynkin gen. n. is erected for two new species described herein: Processuridia thangka S.-Y. Huang Volynkin sp. n. from southeastern Xizang, southwestern China and P. oreas Volynkin S.-Y. Huang sp. n. from southeastern Yunnan, southwestern China and Mt. Fansipan, northern Vietnam, with P. thangka sp. n. as the type species of the genus. Based on molecular phylogenetic analysis, the new genus is found to be sister to the clade (Asuridia Hampson + Disasuridia Fang), but it can be easily distinguished from both genera by the unique wing pattern and genitalia features. Adults and genitalia of the aforementioned taxa are illustrated.

Description of a new species and a new record of the genus Nola Leach, 1815 (Lepidoptera, Nolidae, Nolinae) from Tibet, China.

The genus Nola was established with the western Palaearctic species Noctua cucullatella (Linnaeus, 1758) described from Austria as its type species. Nola occurs in all continents except the Antarctica and contains more than 200 valid Eurasian and North African taxa (László et al., 2014). The genus Nola can be easily distinguished from other genera of Nolinae with the distinctive features as the degenerate uncus, the divided valva with the ventral valval lobe bearing the harpe and a curved carina process in male genitalia. In our recent survey, we report a new species Nola senmuzhaensis sp. nov. and a new record of Nola sikkima (Moore, 1888) from Tibet, China. Adults and genitalia are illustrated. The type specimens are deposited in Southwest University of Science and Technology (SWUST).

A new species of the genus Daplasa Moore from China based on morphological and molecular evidence (Lepidoptera: Erebidae: Lymantriinae).

A new species, Daplasa medoga sp. nov., is described from Tibet, China. The new species can be distinguished morphologically from all other known Daplasa species by its male genitalia with a sagittate uncus and distally broadly crotched valvae. The validity of new species is well supported by the molecular phylogenetic analyses of one mitochondrial gene (COI) and two nuclear genes (EF-1α RPS5), with a total length of 2,324 bp.

Description a new species of Nemacerota Hampson, [1893] (Lepidoptera: Thyatiridae) from the Xizang Autonomous Region, China.

A new species of Nemacerota Hampson, [1893], N. paizhenensis sp. n., is described from the Xizang Autonomous Region (= Tibet), China. The male adult and the genitalia of the new species are illustrated and compared with its most similar species: N. inouei László, Ronkay, Ronkay Witt, 2007 and N. pectinata (Houlbert, 1921); an identification key and distribution map for all Chinese Nemacerota species are provided.

New records and their associated DNA barcodes of the butterfly family Hesperiidae in Tibet, China.

The specimens of the family Hesperiidae collected from Tibet during 2016-2018 are identified using morphology. COI sequences of 76 individuals are newly obtained. The result of our morphological study is congruent with COI gene analyses. Maximum likehood (ML) and Bayesina inferences (BI) analyses reveal that individuals identified morphologically as the same species cluster cohesively. The minimum interspecific genetic distance is 1.7% between Halpe aucma and H. filda, and the genetic distance between conspecific individuals ranged from 0 to 0.2% for the genus Halpe. A total of 51 species are recognized, and six of them, Celaenorrhinus consanguineus Leech, 1891, Barca bicolor (Oberthür, 1896), Aeromachus propinquus Alphéraky, 1897, Pedesta bivitta (Oberthür, 1886), Baoris penicillata chapmani Evans, 1937, and Ochlodes brahma Moore, 1878, are reported from Tibet for the first time, and the last species is new to China.
