Editum editum Fibiger , new species

( Plate 9 , figure 4; male genit. plate 18, figure 4)

Material examined. Holotype: male. Vietnam, 20 km Di Linh (Djiring), 22–28.iv.1960, leg. L.W. Quate, genit. prep. 3333 M. Fibiger, coll. BPBM.

Diagnosis. Imago (external). Wingspan: 10 mm.

Head, patagia, anterior part of tegulae, prothorax, basal part of costa, costal part of medial area, subterminal and terminal areas: blackish brown, costal medial area triangular.

Forewing: ground colour beige.

Abdomen: grey.

Crosslines: untraceable, except terminal line well marked by black interneural dots.

Reniform stigma: whitish, indistinct.

Hindwing: grey, with discal spot.

Underside: forewing brown; hindwing grey, with discal spot.

Male genitalia. Tegumen: extremely thin, threadlike [partly lost during genitalia preparation]; ventral part of tegumen twice as thick, bearing also peniculus.

Peniculus: platelike, 5 times higher than wide (apo.).

Vinculum and saccus: stout, 3 times broader than apical part of tegumen.

Saccus: very short, V shaped.

Diaphragm: almost circular between valvae.

Fultura superior: across diaphragm barlike; laterally fused basally to tegumen; apically free as two asymmetrical, prominent rodlike processes; at tip spined; both processes bifurcate (apo.).

Valvae: short and very wide basally, slightly longer than wide, asymmetrical (apo.).

Clasper: barlike, oblique to valva margins.

Ampulla: very large, bilobed, slightly asymmetrical, apically smoothly rounded, dorsal lobe slightly larger than ventral, almost as long as wide (apo.).

Editum : ovoid, on right side 3 times longer than wide, almost half size of whole of valva, setose; (apo.).

Juxta-anellus plate: small, asymmetrical, located close to saccus in diaphragm.

Phallus: long and narrow; almost equally wide; bent upwards at 2/3; coecum very short, half width of rest of phallus (apo.).

Vesica: with spicules.

Female genitalia. Unknown.

Differential diagnosis. E. editum differs from other Editum species in male genitalia, in:

- narrower and longer peniculus;

- processes of fultura superior: shorter and with less apical spines;

- one curve of phallus.

Distribution. E. editum known only from Vietnam.
