Description

Length of fore wing: „ 22–26 mm; ♀ 26–28.5 mm. Frons and palpus brown, mixed with black, third segment of female palpus elongated to equal one-third length of second segment. Male antennae shortly bipectinate, with antennal branches longer than diameter of flagellum ( Figure 1c, d View Figure 1 ). Abdominal crests pale brown surrounded by black metallic hair-scales. Wings rather broad, hind wing with inner margin a little elongate in male. Outer margins on both wings rounded, without crenulations. Ground colour white, scattered with dense blackish purple scales. Area inside antemedian line of fore wing and terminal area of both wings suffused with olive green. Transverse lines black, gently waved and curved, without any sharp tooth, postmedian line on hind wing generally very faint or invisible. Large reniform discal spot on fore wing always ringed by a black boundary, with

its centre olive green; boundary of hind wing discal spot replaced by an indistinct olive patch. Underside white, markings bright to dark purple, almost identical on both wings; basal area with a quadrate or oval spot in middle of cell, a larger oval or shuttle-like patch below it on fold area (small or wanting in female hindwing), and fold area on fore wing suffused with uniform light violet; discal spots large and distinct on both wings; postmedian line narrow band-like, angled at base of cell, as dark as rings of discal spots; subterminal band a little lighter, extending to outer margin except on apices, which are white on both wings.

Male genitalia ( Figure 62 View Figures 61–64 ). Socii thick and short. Valva strongly produced at middle, much narrower towards apex; basal lobe with its proximal half expanded, terminal half depressed in the middle, in the shape of a peanut. Saccular process thick but somewhat short, apical part expanded, bearing well-developed tiny spines. ‘Y’-shaped cornutus in aedeagus well developed, vesica with an additional small bubble-like sclerite.

Female genitalia ( Figure 75 View Figures 75–78 ). Corpus bursae with evenly tapered sides. Total length of ductus bursae and corpus bursae more than twice as long as apophyses posteriores.

Remarks

Lectotypes for Pachyodes arenaria Leech and Hypochroma danielaria Oberthür are here designated in order to provide certainty and stability. This species, as well as the genus Metallolophia is new to the fauna of Taiwan.

Metallolophia cuneataria Han and Xue sp. nov. ( Figures 28, 29 View Figures 22–43 , 63 View Figures 61–64 , 76 View Figures 75–78 )

Description

Length of fore wing: „ 29 mm; ♀ 32 mm. Very close to M. arenaria (Leech) , but much larger. Frons black in male, pale brown in female, palpus greyish brown. Antennal branches longer than diameter of flagellum in male. Markings of wings similar to arenaria , but differ as follows: discal spot on upperside of fore wing narrower towards costa and expanded near lower end, where it is about twice as wide as at the upper end. Underside with discal spot on fore wing even more sharply expanded toward lower end, becoming pyriform; violet suffusion under cell and Cu 2 more uniform, lacking dark oval patch; subterminal band much weaker.

Male genitalia ( Figure 63 View Figures 61–64 ). Valva less produced at middle and much broadened apically. Basal lobe of valva much broader than in M. arenaria (Leech) . Saccular process slightly thicker than in that species.

Female genitalia ( Figure 76 View Figures 75–78 ). Corpus bursae very long, its total length plus the short ductus bursae more than 3.4 times length of apophyses posteriores.

Diagnosis

Very close to M. arenaria (Leech) , but differs from that species in having the discal spot on the fore wing differently shaped and lacking the dark oval patch beneath the cell on the fore wing underside. The different shape of the valva and its basal lobe in the male and the very long corpus bursae in the female are also distinctive.
