Papillae anales broad and thick, nail-shaped. Apophyses anteriores thick, while the apophyses posteriores thin and approximately equal in length. Ostium bursae relatively straight. Ductus bursae slightly short, with thick anterior half. Antrum cylindrical, strongly sclerotized, extending to membranous and spirally twisted posterior end. Corpus bursae slender, slightly curved, and tie-shaped, covered with fine folds. Remarks. This species was initially described in Sikkim (now a state in India) and later discovered in the Malay Archipelago and mainland Southeast Asia. Its distribution is the broadest among the four species in the genus, ranging from the northeastern Himalayas to Sumatra and Borneo. Compared to other species, C. pilcheri displays a wider variation in appearance with regionally specific phenotypes. This is mainly seen in the presence or absence of certain small spots (Figs 19, 20, 21): specimens from the Himalayan region (India: Sikkim, China: Xizang, Nepal and Bhutan), have a black-dot orbicular spot; one subbasal line; and two or three black spots near the inner margin of the forewing subterminal line. In specimens from mainland Southeast Asia (China: Yunnan, Thailand), these black spots are often absent. In specimens from the Malay Archipelago, only the black spots on the subbasal line near the inner margin are present. However, specimens collected from Xizang, Yunnan, and Borneo have only slight differences in genitalia, particularly in the smooth, small cornuti row located at the posterior part of the dorsal side of the vesica, which is a distinctive feature of the species. The variations in appearance are not significant enough to warrant interspecific differentiation. Therefore, in this article, they are considered geographical variants of the same species, and their relationship needs further clarification in conjunction with molecular data. Distribution. China (Yunnan, Xizang); India, Nepal, Bhutan, Thailand, Malaysia, Indonesia.
