Longiantrum coclea Fibiger View in CoL , new species

( Plate 7 View PLATE 7 , figure 1; female genit. plate 24, figure 3)

Material examined. Holotype. Female. Vietnam N, Ban En Base Camp , 31.x.1998, leg. Frontier VN 9804, genit. prep. 6063 M. Fibiger, coll. HNHM.

Diagnosis. Imago (external). Wingspan: from 11 mm.

Head, patagia, anterior part of tegulae, prothorax, basal part of costa, costal part of medial area, and terminal area, including fringes: black; costal medial area quadrangular.

Forewing ground colour: beige throughout, suffused with few black scales.

Crosslines: all lines indistinct, black, except terminal line marked by black interneural dots.

Reniform stigma: indistinct; white; outlined yellow.

Hindwing: grey, terminal line light brown.

Underside: forewing light brown, hindwing grey.

Female genitalia. Ovipositor: short, smoothly rounded posteriorly and at corners.

Posterior apophyses: 1.25 longer than ovipositor.

Anterior apophyses: 0.8 length of posterior apophyses; arising free from fusion of 7 th and 8 th segment (apo.).

7 th and 8 th abdominal segment: strongly fused (apo.).

Ostium: wide; displaced to left, positioned from middle of 7 th segment to fusion between 7 th and 8 th segments.

Antrum: cylindrical; long and strongly coiled.

Ductus bursae: membranous, long and narrow; strongly coiled from antrum; twice as long as corpus bursae (apo.).

Corpus bursae: globular.

Differential diagnosis. L. coclea differs from other Longiantrum species in female genitalia, in:

- proportion of length between anterior and posterior apophyses;

- 7 th and 8 th segment tightly fused;

- shape and sclerotisation of antrum;

- coiling and length of ductus bursae.

Distribution. L. coclea known only from N. Vietnam.
