Type species: Pluma shuni Liang, Solovyev & Wang sp. nov., by present designation.

Diagnosis. The genus is diagnosed by the following characters: (1) bipectinate antennae up to the tip with long rami; (2) hardly separable obscure dark postmedial fascia running from wing apex to 2/3 dorsum; (3) male genitalia with unmodified uncus, gnathos, valvae and juxta, short and robust aedeagus, vesica with two or three large clusters of bristle-shaped cornuti.

Description. Male adults ( Figs 2–5 View FIGURES 2–5 ). Small sized moths. Forewing length 8–14 mm, wingspan 17–28 mm. Head. Antennae strongly bipectinate, each ramus with many trichoid sensilla ( Fig. 6 View FIGURES 6–7 ). Frons flattened with beige-brown bristles. Labial palpus pale straight, about 1.5–2.0 times as long as diameter of compound eyes ( Fig. 7 View FIGURES 6–7 ). Ocellus absent, and proboscis reduced.

Thorax. Tibia spur formula: 0-2-4. Forewing ground color gray or brown, uniform, with hardly separable obscure dark postmedial fascia running from wing apex to 2/3 dorsum.

Venation ( Figs 12–13 View FIGURE 12 View FIGURE 13 ): Frenulum developed. Forewing: Sc and R 1 almost parallel, R 2, R 3 and R 4 stalked, the discal cell split with M 1. Hind wing: in Sc+R1, R 1 is partially or completely fused with Sc; Rs and M 1 on the short base, vein M bisecting the cell.

Male genitalia ( Figs 8–11 View FIGURES 8–11 ). Uncus well developed, with sclerotized apical spur. Gnathos strong and slender. Valvae elongate without saccular process, rounded apically. Juxta simple and flattened. Aedeagus short and wide. Vesica with two or three large clusters of bristle-shaped cornuti.

Female unknown.

Etymology. The specific name is given after the Latin “ Pluma ” — feather, meaning adults of this genus with strongly bipectinate, feather-like antennae.

Comments. The phylogenetic relationships of the genus and the corresponding lineage within south-east Asian Limacodidae (sensu Holloway, 1986; Holloway et al., 1987) are not clear as no data on immature stages and female morphology.
