Diagnosis.

Externally (Figs 15 , 24 ) the male of C. polyakovi sp. nov. differs from other Carriola by the presence of a hyaline window at the base of the forewing, which sometimes merges into the central window. The female can only be identified by examination of the genitalia. The male genitalia are characterised by the shape of the valva. It is strongly elongated and tapers from the base to the distal margin, with its tip strongly curved upwards. The tip is rounded and serrated. (Fig. 33 ). The female genitalia differ from those of related species by the signum, which is as large as ⅓ of the corpus bursae, and distinctly V-shaped with pronounced lateral lobes, which have the same width at the point of closure as along their entire length. The length of lobe is 0.4 times the width of the signum. (Fig. 42 ).

Description.

External appearance. Head. Frons and vertex golden brown, and covered with dense drooping scales, with small tufts at the base of the antennae. Eyes large and round. Labial palpi bent obliquely upwards, densely hairy, pale on the underside and of the same pale olive colour as the abdomen; dorsally golden brown. Forewing (Figs 15 , 24 ) triangular with rounded apex. The ratio between the length of the forewing margin and costa about 1.2:1 in both sexes. Male forewings of beige-green ground colour and typically with three hyaline windows (Figs 15 , 24a, b ). Length of forewing 12.8-16.8 mm (13.5 mm in holotype). Central window occupied central cell and extended to half of the cells: M2-M3, M3-CuA1, CuA1-CuA2, and CuA2-1+2A and bordered by clearly visible antemedial and subterminal lines. Basal hyaline window located at wing root and bordered by basal and antemedial lines. Hyaline satellite oval and located between RS4-M1 and bordered by postmedial and subterminal lines; discal spot chevron-shaped. Underside of forewing with lighter monotonous background, hyaline windows lined with brown scales (Fig. 24b ). Male hindwings (Figs 15 , 24a, b ) triangular with rounded tip. General outline of pattern, colour and type of arrangement of central hyaline windows repeat the forewing. Two triangular hyaline satellite windows present, one between veins Sc+R1 and Rs, and the second between veins Rs and M1 (Fig. 15 ). Female forewings of olive colour and with large hyaline window bordered by clearly visible terminal line (Fig. 24c ). Length of forewing 14-17 mm. Female hindwings triangular with rounded tip. The general outline of pattern, colour and type of arrangement of hyaline window repeat the forewing. Male genitalia (Figs 33a-c ). Superuncus rectangular and slightly divided into two lobes at apex (Fig. 33c ). Uncus (Fig. 33a ) short and rounded. Valva elongated and strongly tapered from base to distal margin, its tip curved upwards, with small teeth at the end. Width of basal part of valva in a ratio of 1:3.5 to length of valva (Fig. 33a ). Juxta U-shaped. Aedeagus short, wide as half the length, strongly bevelled at its anterior and posterior end (Fig. 33b ). Female genitalia (Fig. 42 ). Papillae anales weakly sclerotised, broad and rounded, pseudopapillae small and narrow, membranous. Posterior apophyses slender to ⅔ the length of papillae anales. Antrum bowl-shaped, small. Ductus bursae membranous, strongly constricted before antrum and gradually widening before corpus bursae. Signum scobinate, V-shaped, large as ⅓ of the corpus bursa with distinct elongate, outwardly curved lateral lobes as long as 0.4 times as wide as the signum.

Biology.

Unknown. The flight period is from January to December. The species has been collected at elevations ranging from 50 to 800 m.a.s.l.

Distribution.

(Fig. 50 ). Philippines (Luzon, Panay, Negros and Samar).

Etymology.

The species is dedicated to the memory of Prof. Viktor P. Polyakov (Samara Province, Russia), an outstanding cardiovascular surgeon, a scientist in the field of cardiology and an organiser of the regional school for training in cardiovascular surgery, which is based on the Samara Regional Clinical Cardiology Dispensary named after V.P. Polyakov and the Samara State Medical University.
