Remarks. 1) In the analysis, the genus Ovipennis is found to be a monophyletic group receiving strong support from both methods ( Fig. 1 , UFBS=100, PP=1). Nanarsine milani is embedded in Ovipennis and clustered with Ovipennis multicornuta sp. n. with moderate support from both methods ( Fig. 1 , UFBS=63, PP=0.58), while the type species of the genus Nanarsine Volynkin, 2019 , N. porphyrea ( Snellen, 1880) is grouped with the species of the genera Barsilene Volynkin & Huang, 2019 , Floridasura Volynkin, 2019 and Asura Walker, 1854 and the topology of this part is exactly the same as in Huang et al. (2021). Hence we transfer this species from Nanarsine to Ovipennis , viz. O. milani ( Černý, 2009) comb. n. 2) This species is hereby recorded from Vietnam and China for the first time.

Diagnosis. Ovipennis milani is characterized by the presence of a large golden patch on forewing and a short blackish streak on forewing dorsum. In male genitalia, the species is characterized by the sack-like phallus vesica with two clusters of small cornuti, of which one is positioned basally while the other one is positioned at the surface of a small diverticulum distally.

Distribution. Northern Thailand, Northern Vietnam * and Southwestern China *(Xizang, Yunnan).

FIGURE 1. Molecular phylogenetic tree recovered from the Maximum likelihood inference analysis of the combined dataset with the best-fit partitioning strategy. The clades were mostly folded except for the genus Ovipennis. The branch of the species Nanarsine milani was marked out by red. The order of the values on the nodes is as follows: ultrafast bootstrap values (UFBS) in IQtree / posterior probabilities (PP) of the Bayesian analysis.
