The genus Phrixolepia Butler, 1877 is revised and its diagnosis is given. At present, the genus comprises 10 species, three of which are described
as new (all the holotypes and paratypes are deposited in MWM): Ph. pudovkini Solovyev, sp. n., LT: “China, Shaanxi prov., Taibai Shan, Tsinling Mts., Houzhenzi, 33°53′ N; 107°49′ E, 1500 m,” genital
slide 11389; Ph. sinyaevi Solovyev, sp. n., LT: “N.
... [Show full abstract] Vietnam, Cuc. Phuong, 60 km SW Hanoi, 20°15′ N; 105°20′ E, 400 m,” genital slide 11386; Ph. nigra Solovyev, sp. n., LT: “China, prov. Yunnan, Yunlong, Fengshuining Mts., 13 km N of Caojian, 2460 m,” genital slide 11391.
All the species are very similar externally, except for differences in size, tints of the coloration, and the presence of
a semi-ovoid bright apical spot in the fore wing. The features of the male genitalia are diagnostic. A key to the species
is given. The phylogenetic relationships between the species are examined. The genus is closely related to Olona Snellen, 1900 and Phobetron Hübner, 1825, based on the characters of larval morphology. A similar larval morphology also found in the family Dalceridae
could be a synapomorphy of the families Limacodidae and Dalceridae.
