Euphlyctina butvilai sp. nov.

( Figs 7, 8 , 18 )

Type-material. Holotype: ♂, [ China, Zhejiang] “ West Tien-mu-shan | Prov. Chekiang | 18.6.1932, H. Höne [leg.]” ( ZFMK, genital slide № 10-41) . Paratype: 1♂, China, NW Yunnan, Nu Jiang valley, Fugong / Gongshan , 27˚18.24’’ N, 98˚53.20’’, 1800 m, 17.v.2018, leg. Butvila & Saldaitis ( CASV, genital slide № CAS-20-04) .

Description. Male. Forewing length 8.0– 9.5 mm ( Figs 7, 8 ). Antenna filiform. Ground color ochre to bronzy brown. Forewings bronzy brown, with contrasting white large subapical mark, discal white spot (located at the base of the veins M2 and M3), and very small apical black comma-like mark. Hindwing greyish brown. Abdomen yellow. Sternite VIII with a pair of long strongly sclerotized piliform processes.

Genitalia. Uncus broad, with apical small papilla ( Fig. 18 ). Gnathos slender, sickle-shaped, widened apically. Valvae elongated, with large sickle-shaped saccular processes. Juxtal lateral processes long, slender, approximately equal in size, medially enlarged. Aedeagus small, slender, sinuous.

Female. Unknown.

Diagnosis. This species is well separated from its only congener, Euphlyctina phaeopasta ( Hampson, 1906) ( Fig. 9 ) by the forewings with a white large subapical mark, a large white discal spot and a black apical comma-like mark. The male genitalia are also diagnostic: the juxta bears two pointed and slender lateral processes, approximately equal in length, and medially enlarged; whereas these processes are broad, unequal in length, crescent-shaped, and without the enlarged medial part in E. phaeopasta ( Fig. 19 ). The saccular processes of valva are located more distally in E. phaeopasta with a distance from the valvar apex equal in length to the saccular process, while in E. butvilai sp. nov. this distance is equal to 1.5 the length of the saccular process.

Distribution. China (Zhejiang, Yunnan).

Phenology and habitat. The holotype specimen was collected on the 18th of June, whilst the paratype was collected at ultraviolet light in mid May. The new species was collected at an altitude of approximately 1,800 m asl in primary mountains mixed forest, dominated by various deciduous trees, bamboo and shrubs ( Figs 34, 35 ).

Etymology. The new species is named after our colleague and prominent Lithuanian collector Rimantas Butvila (Joniškis, Lithuania).

Remarks. The male from Yunnan designated as paratype has minor differences compared to the holotype, including shape of the forewings and coloration, however, at this stage, these differences are regarded as intraspecific variations.
