Diagnosis.

Externally (Figs 16 , 25 ) C. shorokhovi sp. nov. can be confused with C. thyridophora , C. witti and C. seminsula , and identification can only be made by examining the genital structures. The male genitalia differ in the shape of the valva. In C. shorokhovi sp. nov., the valva is elongated and pointed from the base to the distal margin as in C. polyakovi , but its tip is not curved upwards (Fig. 34 ). The signum is present, scobinate V-shaped and as large as three quarters of the bursa. The lobes of the signum are thickened and poorly separated and as long as 0.4 times as wide as the signum (Fig. 43 ).

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 and golden brown and pale olive coloured on the underside. Male antennae bipectinate with long branches, female antennae similar in structure but less developed. Forewing (Figs 16 , 25a b) triangular with a ratio of margin to costa of about 1.2:1 in both sexes, tip of forewing rounded. Male forewings with beige-green ground colour and typically with two hyaline windows. Length of forewing 12.5-16.5 mm (13.5 mm in holotype). The central window occupies the central cell and covers up to half the length of cells between M2-M3, M3-CuA1, CuA1-CuA2, and CuA2-1+2A, and bordered by antemedial and subterminal lines. Hyaline satellite oval and located between RS4 and M1, veins and bordered by postmedial and subterminal lines; discal spot chevron-shaped. Underside of forewings with lighter, monotonous background, without pronounced banding pattern, but with distinct brown border around hyaline windows (Fig. 25b ). Male hindwings (Figs 15 , 24a, b ) with arrangement of central hyaline window repeating pattern of forewing. Length of forewing 14.5-17 mm. 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 olive coloured with large hyaline window bordered by clearly visible terminal line (Fig. 25c ). Female hindwings with general outline of pattern colour, and type of arrangement of hyaline window repeated forewing. Male genitalia (Figs 34a-c ). Superuncus subrectangular and slightly divided into two lobes at apex (Fig. 34c ). Uncus (Fig. 34a ) with broad base, gradually tapering towards apex. Valva straight, elongate and tapering from base to distal margin, rounded and toothed at apex. Width of basal part of valva in a ratio of 1:3.5 to the length of valva (Fig. 34a ). Juxta U-shaped, rectangular, ratio length to width 1:1.5. Aedeagus short, wide as half the length, strongly bevelled at anterior and posterior end (Fig. 34b ). Female genitalia (Fig. 43 ). Papillae anales weakly sclerotised, broad and rounded, pseudopapillae small, narrow and clearly separated. Posterior apophyses slender to ⅔ the length of lobes of papillae anales. Antrum cup-shaped, small. Ductus bursae membranous, strongly constricted before antrum, and gradually widened before entrance to corpus bursae. Corpus bursae rounded, rather short and as long as ductus bursae. Signum, scobinated, V-shaped, as large as three quarters of bursa. Lobes of signum thickened, weakly separated, as long as 0.4 times as width of signum.

Biology.

Unknown. The adults are common all year round and can be found in wooded lowlands up to 1140 m.a.s.l.

Distribution.

(Fig. 51 ). Philippines (Mindanao, Mindoro and Leyte).

Etymology.

This species is named after Prof. Sergey E. Shorokhov (Samara Province, Russia), a leading cardiovascular surgeon in the Department of Paediatric Cardiac Surgery and Cardiorheumatology at the Samara Regional Clinical Cardiology Dispensary, who has assembled a team of professional colleagues who save children's lives every day.
