Metallolophia medullosa Inoue

( Figures 16, 17 , 59 , 73 ) Metallolophia medullosa Inoue, 1988: 97 , Figures 1a, b , 2a . Holotype „, [ Philippines]: Mindanao, Davao, Upper Baracatan, Apo Range , Mt Talomo , 1100 m ( NSMT).

Description

Length of fore wing: „ 22–24 mm; ♀ 24 mm. Antennae in both sexes filiform. Differs from congeners in broader wings, reminiscent of Pingasa . Wings white, basal and terminal area olive-green. Fore wing with a double wave in the antemedian line, inner margin of discal spots deeply concave; postmedian line olive-green, dentate; an indistinct white patch at the middle of the terminal dark band. Hind wing with discal spot very faint. Underside white, fore wing with purplish tinge, a dark purple spot proximal to discal spot and a shuttle-like patch below the origin of Cu 2; hind wing underside with a very small discal spot; terminal area of both wings underside occupied by a dark purple band, with white spots at apex and middle.

Male genitalia ( Figure 59 ). Near M. subradiata (Warren) . Socii narrower than in that species. Terminal half of valva triangular; basal lobe very narrow and small. Stick-like saccular process much broader at terminal half. Aedeagus shorter than in M. subradiata (Warren) . Male abdomen lacking setal patches on third sternite.

Female genitalia ( Figure 73 ). Close to those of M. albescens Inoue. Ductus bursae shorter and broader, lamella postvaginalis smaller.
