Diagnosis.

Dasypolia luxuriosa sp. nov. is externally vaguely reminiscent of D. ultramontana sp. nov. but differs in the shorter rami of the male antenna, the larger size, the broader forewing, the darker grey forewing ground colour, the less sinuous antemedial line, and the narrower, falcate reniform marking lacking the dark core spot. Additionally, unlike in D. ultramontana sp. nov., the inner triangular dashes of the subterminal line of D. luxuriosa sp. nov. are more distinct and longer, and the hindwing is suffused with brownish-grey medially and along the anal margin whereas in D. ultramontana sp. nov. it is paler but with intense grey suffusion along the costal and outer margins. The male genitalia of the two species are similar but in D. luxuriosa sp. nov. the uncus is somewhat longer, the juxta is broader, the sacculus is narrower, and the vesica lacks the ventral diverticulum. As the female of D. ultramontana sp. nov. is unknown, the female genitalia of D. luxuriosa sp. nov. were compared with D. amoena sp. nov., a detailed comparison with which is provided above in the diagnosis of the latter species.

Description.

External morphology of adults (Figs 29–34 ). Forewing length 14.0–15.0 mm in males and 14.0 mm in females. Antenna shortly bipectinate in male and filiform in female. Head and thorax dark grey with admixture of pale grey. Forewing triangular with rounded apex and convex anal margin. Forewing ground colour grey with slight dark grey suffusion. Pattern elements blackish. Subbasal and antemedial lines irregularly sinuous, antemedial one edged with pale ochreous grey inwardly. Costa with series of irregular blackish spots. Orbicular marking elliptical, small, with blackish margins, filled with pale grey or off-white. Reniform marking semilunar, with blackish margins, filled with off-white. Postmedial line question mark-like curved, irregularly dentate on veins, edged with pale ochreous grey outwardly. Subterminal line irregular, interrupted into series of triangular dashes of different sizes. Terminal line thin, interrupted on veins. Cilia dark grey with admixture of pale grey scales. Hindwing pale ochreous grey with slight dark grey suffusion along costal and outer margins. Discal spot semilunar, diffuse. Terminal line thin, ochreous grey. Hindwing cilia grey. Male genitalia (Figs 53 , 54 ). Uncus swollen, elongate, distally tapered and apically pointed. Tegumen with rounded and swollen penicular lobes. Vinculum somewhat longer than tegumen, heavily sclerotised, U-shaped. Valva lobular, slightly tapered distally. Costa distally dilated and reaching cucullus. Cucullus rounded and densely covered with setae. Editum thin, stretching along ventral margin of costa and dorsally fused with it, bearing narrow triangular distal ampulla directed ventrally and not protruding the ventral margin of valva. Sacculus trapezoidal, ~ 1 / 2 of valva width. Clasper oblique, ventrally straight and dorsally dilated and upcurved, bearing clavate harpe protruding beyond dorsal margin of valva. Valvula short but broad, not protruding ventrally. Juxta trapezoidal with short, triangular medio-dorsal process. Phallus cylindrical with rounded coecum, somewhat downcurved postmedially. Proximal section of vesica elliptical, broader than phallus, weakly granulose and bearing two bunch-like clusters of spine-like cornuti on lateral sides. Vesica ejaculatorius tubular and distally directed. Female genitalia (Fig. 66 ). Ovipositor broad and conical. Papilla analis trapezoidal with rounded corners, setose. Apophyses elongate and thin, rod-like, anterior one longer than posterior one. Ostium bursae moderately broad, with membranous margins. Posterior section of ductus bursae funnel-like dilated posteriorly, with medial rectangular sclerotised plate with postero-medial depression. Anterior section of ductus bursae irregularly globular, swollen, gelatinous with two rounded sclerotised plates of different sizes. Corpus bursae membranous, strongly elongate, with tubular posterior and pear-shaped anterior sections. Appendix bursae vestigial, ductus ejaculatorius originating posteriorly at junction with anterior gelatinous section of ductus bursae.

Etymology.

The specific epithet is a Latin adjective meaning luxurious and refers to the beautiful external appearance of the new species.

Distribution.

The new species is currently known from its type locality in southern Xizang, China.
