Diagnosis.

Externally, the male of C. zolotuhini sp. nov. is easily distinguished from other Carriola by its dark grey colour and the absence of a hyaline window on the hindwings (Figs 18 , 27 ). The male genitalia differ from those of the related species by the broad superuncus, the width of which is in a ratio of 2:1 to the length (Fig. 36c ). The valva is rectangular and has the characteristic folds: a curved saccular fold with a downwardly curved process and a broad costal fold. The width of the basal part of the valva has a ratio of 1:2.4 to the length of the valva (Fig. 36a ).

Description.

External appearance. Head. Frons and vertex dark grey and covered with dense, drooping scales, with small tufts at the base of antennae. Eyes large, round. Labial palpi obliquely curved upwards, densely hairy, on underside of the same grey colour as abdomen; dorsally dark brown. Male antennae bipectinate with long branches. Male forewings (Figs 18 , 27a, b ) triangular with pointed tip. Ground colour dark grey, with central hyaline window. Length is 13-13.5 mm (13.2 mm in the holotype). The ratio between the length of forewing margin and costa is 1.2:1. Central hyaline window occupies central cell and covers up to half the length of the cells between veins M2-M3, M3-CuA1, CuA1-CuA2 and CuA2-1+2A. Hyaline windows covered by sparse black scales, which make them appear blurred and without clear boundaries, and bordered by faintly visible antemedial and subterminal lines of black scales; discal spot chevron-shaped. Underside of forewing with dark grey, monochrome background (Fig. 27b ). Male hindwings (Figs 18 , 27a, b ) same coloured as forewing without hyaline window, costal margin brownish. Male genitalia (Figs 36a, b, c ). Superuncus very broad, its width in a ratio of 2:1 to length, slightly divided into two lobes at apex (Fig. 36c ). Uncus (Fig. 36a ) short, with slightly constricted base and apically rounded. Valva rectangular with sclerotised curved fold originating from base of sacculus and ending in downward curved sclerotised pointed process extending to distal ⅓ of valva. Costal margin of valva with additional broad sclerotised pocket-like fold. The ratio of the width of the basal part of the valva to the length of the valva is approximately 1:2.4. Juxta A-shaped, triangular, ratio length to width as 1.5:1. Aedeagus short, strongly bevelled at its anterior and posterior end. Everted vesica round, without cornuti, covered with very small spinules (Fig. 36b ). Female. Unknown.

Biology.

Unknown. The flight period is from February to April. The species occurs in wooded lowlands up to an elevation of 300 m.a.s.l.

Distribution.

(Fig. 53 ). Philippines (Mindanao).

Etymology.

This species is dedicated to the memory of Dr. Vadim V. Zolotuhin, a famous lepidopterist, whose kind help and support was always invaluable to the authors.
