( Plate 6 View PLATE 6 , figure 6; male genit. plate 16, figure 2)

Material examined. Holotype: female, Thailand, Prov. Nakhon Nayok, Khao Yai Nat. Park , ca. 700 m, 29.ix.– 6.x.1984, leg O. Karsholt et al., genit. prep. 2936 M. Fibiger, coll. ZMUC.

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

Head, patagia, anterior part of tegulae, prothorax, basal part of costa, triangular patch of medial area, outer part of subterminal area, and terminal area, including outer half of fringes: black (apo.).

Forewing: long and narrow, with pointed apex; white ground colour (apo.).

Abdomen: dark grey, with dorsal tuft on basal segment.

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

Reniform stigma: white, ovoid, brown outlined.

Hindwing: grey; with narrow brown terminal line and indistinct discal spot; fringes basally beige, outwards grey.

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

Male genitalia. Tegumen: narrow.

Vinculum: relatively narrow.

Saccus: short; strongly built, V shaped with rounded tip.

Fultura superior: membranous.

Valvae: slightly asymmetrical; extremely long and narrow (apo.).

Clasper: sickle shaped (apo.).

Ampulla: bilobed; ventral lobe almost circular; dorsal lobe large, fingerlike, curved; setose at tip (apo.).

Digitus: present; triangular (apo.).

Juxta-anellus plate: inseparable (phallus on left side); anellar plate extremely long and stout; outwards from middle straight, longitudinally setose along crest (apo.).

Phallus: very short, broad, and almost straight; with short carina spine; a prominently long, forward directed process arising near ductus ejaculatorius (a stop-function connected with juxta-anellus ventral processes) (apo.).

Vesica: with spinules, platelike cornutus present (on photo visible inside vesica above ductus ejaculatorius) (apo.).

Differential diagnosis. F. papei closely related to F.s-forma but differs from this and other Fustis species in:

- white ground colour;

male genitalia, in

- clasper sickle shaped;

- ampulla bilobed, ventral part round, dorsal part fingerlike;

- anellus long, curved, subapically and apically setose, pointed anellus;

- phallus short, almost straight, with medial process; and

- vesica with small, short, rectangular, heavily sclerotised plate; and spinules.

Distribution. F. papei known only from Thailand.
