Metallolophia inanularia Han and Xue sp. nov.

( Figures 30, 31 , 77 )

Description

Female. Length of fore wing: 30 mm. Large. Frons black, palpus brown, mixed with grey. Body and wings scattered with extensive olive green. Outer margins of both wings weakly crenulate. Fore wing with transverse lines much thicker than in the two previous species; antemedian line deeply curved convexly, not with a double undulation as in its allies; postmedian line angled on M 3 (curved in the previous two species); large olive green discal spot almost without ring. Hind wing with discal spot very weak, the black postmedian line thin and clear. On underside, discal spots large, especially on hind wing, where spot expanded on both sides, proximally touching the patch in the cell and distally extending to the band-like postmedian line, which on both wings placed more proximally than in the allied species; subterminal band dark purple but much reduced, becoming a row of joined spots below M 3 on both wings; without light violet suffusion below cell and Cu 2 on fore wing, which is present in allied species.

Female genitalia ( Figure 77 ). Ductus bursae and corpus bursae very short, pyriform, total length a little shorter than length of apophyses posteriores. Lamella postvaginalis broad, rectangular.

Male. Unknown.

Diagnosis

Weakly crenulate outer margins of both wings, absence of black ring on fore wing discal spot, curved antemedian and angled postmedian lines all distinguish this species from allied species. The female genitalia are very different from the previous two species, more similar to those of M. albescens Inoue , the markings of which are however different.
