Holotype.

♂, China, Prov. Yunnan, Puer City, Manxieba, 3.VIII.2018, leg. HL. Han, J. Wu, MR. Li, genit. prep. WuJ-237-1 (NEFU).

Paratypes.

1♂, same data as for holotype, genit. prep. WuJ-236-1 (NEFU); 1♂, Vietnam, Dong Nai, Vinh Cuu Nat. Res., Phu Ly, Dakinde, 11.41203°N, 107.10508°E, 106 m a.s.l., 27.VI.2011, leg. A. Solovyev, S. Pugaev, S. Nedoshivina, genit. prep. 0234 (CASU).

Diagnosis.

The new species can be clearly distinguished from the known species in its appearance: the dark brown area at the base of the forewing has no obvious borderline with the ground colour and has no apical patch. In the male genitalia, the new species is similar to P. chihpyh (Fig. 16 ), but uncus rod-shaped and not divided into two parts apically is the main combination that distinguishes the new species from P. chihpyh and from all other known species in this genus.

Description.

Adult (Figs 7 , 8 , 9 ). Wingspan 14 mm in male. Head brown, with golden scales on the frons; labial palpus up-curved, golden; antenna filiform in male, brown. Thorax golden, mixed brown scales; tegula brown. Scales on legs dark brown to golden. Forewing ground colour yellowish brown, dark brown at ca. 1/3 from wing base and costal margin area and no clear borderline with the ground colour; fringe long, especially in the tornus area, yellow; forewing without other lines. Hindwing ground colour reddish brown; fringe long, yellow to light brown, but dark brown in costal area. Abdomen dark brown, with light brown and golden hairs between each abdominal segment.

Male genitalia (Figs 13 , 14 , 15 ). Uncus short, rod-shaped, slightly enlarged and rounded apically, covered with dense hairs. Gnathos reduced to a small plate. Tegumen broad. Transtilla very developed and strongly sclerotized, wide at base, slightly narrower in apical part and with semicircular depression in middle of apex. Valva strongly modified, clearly divided into two parts: upper part finger-shaped, slightly thin at middle and covered with dense hairs on apex; in basal part, sacculus visibly enlarged, bearing swollen base and eagle-claw-shaped sacculus process; small triangular structure located at base of sacculus process. Juxta shield-shaped. Saccus not obvious. Phallus slender, tube-shaped, slightly curved at middle.

Female genitalia. Unknown.

Distribution.

China (Yunnan), Vietnam (Dong Nai) (Fig. 20 ).

Etymology.

The species is named Pseudidonauton puera (a noun in apposition) after its type locality in Puer City, Prov. Yunnan, China, which is famous for Puer tea.

Bionomics.

The moths fly in late June and August. The Chinese specimens were collected with a light trap close to a coniferous forest; the main vegetation around the collecting site consists of Pinus yunnanensis Franch. ( Pinaceae ).
