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 .
