Metallolophia devecisi Herbulot View in CoL

( Figures 36–39 View Figures 22–43 , 52, 65, 78) Metallolophia devecisi Herbulot, 1989: 171 , Figures 2, 3 View Figures 2–21 . Holotype „, West Malaysia [Peninsular Malaysia]: Cameron Highlands, Strawberry Park ( ZSM).

Description

Length of fore wing: „ 26 mm; ♀ 27 mm. Very similar to the previous species M. ocellata (Warren) . Frons and terminal part of palpus blackish brown. Abdominal crests almost without blackish hair. Wings, especially inner margin of hind wing, narrower and more elongate than ocellata . Fore wing with pale band below costa more conspicuous, hind wing with olive-green much extended along veins. Underside similar to ocellata , except that postmedian fascia on fore wing is rounded from costa to M 3, then continuous to Cu 2, where it bends outwards and forms a distinct angle at its inner margin.

Male genitalia ( Figure 65 View Figures 65–67 ). Very similar to those of M. ocellata . Valva not narrowed towards apex; basal lobe of valva a little smaller.

Female genitalia ( Figure 78 View Figures 75–78 ). Ductus bursae not clearly differentiated from corpus bursae, with a distinct sclerotized ring. Corpus bursae small and pyriform, with weakly sclerotized ridges on the posterior half.

Remarks

G. Orhant (personal communication) stated that ‘ Metallolophia devecisi Herbulot, 1989 is certainly a synonym or a ssp of M. ocellata (Warren) . I have in my collection 2 males of M. ocellata . It is really the same’. Mr Sommerer (personal communication) found, based on his collection from Sumatra, significant differences in the postmedian fascia on the fore wing underside. However, he was only able to compare his males with the type female in BMNH. With the kind help of both parties, we have been able to compare males from the subcontinent and South-East Asia more meticulously, in respect of both facies and genitalia. On the basis of the male antenna, the general aspect and the distribution range, we believe that the male specimens from North-East India collected by G. Orhant are true M. ocellata (Warren) , while the male specimens from Sumatra collected by Mr Sommerer are specifically distinct, and referable to M. devecisi Herbulot. The latter differs from M. ocellata (Warren) in many respects, most notably the different male wing shape, and should be considered as distinct at the specific level. There are also two males in coll. A. Pinratana, Bangkok, from Doi Inthanon, Chiangmai Province, North Thailand, collected in November 1997. These have been checked by Dr D. Stüning, who also provided digital images. We believe that these are also devecisi . The female of this species is described here for the first time.
