Editum editoides Fibiger , new species

( Plate 9 , figure 3; male genit. plate 18, figure 3)

Material examined. Holotype: male, Vietnam S, Mt. Ngoc Linh , 900–1400 m, 10–25.viii.1996, leg. Siniaev & Afonin, genit. prep. 3334 M. Fibiger, coll. ZMHB.

Paratype: 1 male, Vietnam, Prov. Kon Tum, Ngoe Linh Nature Reserve , 1750 m, -. iii.1998, leg. A. Monastyrski, genit. prep. 5925 M. Fibiger, coll. MF .

Diagnosis. Imago (external). Wingspan: 12 mm.

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

Forewing: ground colour light brown.

Abdomen: grey, with dorsal tuft on basal segment.

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

Reniform: beige, indistinct.

Hindwing: grey, with discal spot.

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

Male genitalia. Tegumen: extremely thin, threadlike; ventral part of tegumen twice a thick, bearing also peniculus.

Peniculus: platelike, 1.5 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, prominently long, rodlike processes; at tip spined; left process with 5 spines; right process clublike, with spines on club (apo.).

Valvae: shorter than wide, asymmetrical (apo.).

Clasper: barlike, oblique to valva margins.

Ampulla: very large, bilobed, slightly asymmetrical, basally and apically sides almost parallel, dorsal lobe slightly larger than ventral one, twice as long as wide (apo.).

Editum : enormous, ovoid, twice as long as wide; almost half size of whole of valva; setose.

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

Phallus: long and narrow; almost equally wide; bent two times: downwards by ductus ejaculatorius, at 2/3 upwards/backwards; curved between bends; coecum very short, half width of rest of phallus (apo.).

Vesica: with spicules.

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

- broader peniculus;

- processes of fultura superior: longer and more apical spines;

- broader valva;

- ampulla shorter, almost parallel basally and apically;

- shorter editum;

- two curves of phallus.

Distribution. E. editoides known only from Vietnam.
