( Plate 9 View PLATE 9 , figure 5; male genit. plate19, figure 4)

Material examined.

Holotype: male, Philippines, Balawan , Mt. St. Paul , Babuyan, Cayasan, 5–6.iv.1995, leg. W. Mey, genit. prep. 3298 M. Fibiger. Coll. ZMHB.

Diagnosis.

Wingspan: 10 mm.

Forewing: narrow, light brown in medial and anterior part of subterminal areas, other areas of forewing blackish brown.

Transverse lines: brown; terminal line marked by black dots between veins.

Reniform: distinct, whitish grey, outlined by black.

Fringes: coloured like terminal area.

Hindwing: unicolorous grey brown with an indistinct black discal spot.

Underside: unicolorous grey brown.

Male genitalia.

Tegumen: narrow.

Vinculum: short, stout.

Saccus: U-shaped, short.

Fultura superior: Y-shaped with long narrow arms, fused medially with tegumen and ventrally fused broadly with juxta-anellus plate; from middle a single, very long, narrow, S-shaped, ventrally directed process arises.

Valve: shorter than wide.

Ampulla: almost symmetrical; long, very narrow, club-like; subapically densely setose with long, hair-like, inwardly bent setae.

Pollex : relatively short, finger-like on right side; left pollex broad medially, then tapered towards tip; both sides subapically densely setose with long, hair-like, inwardly bent setae.

Digitus: huge on right side, strongly curving ventrally, bifurcate towards apex; left ampulla short, apically pointed.

Juxta-anellus plate: higher than wide, hole for phallus positioned medially.

Phallus: long, curved, slightly tapered towards apex; coecum short and narrow.

Vesica: unarmed.

Differential diagnosis.

P. diabolo differs from other species by the long S-shaped process from the fultura superior, the strongly asymmetrical digitus, which is bifurcate, the right ampulla, which is club-like, and the pollex, which is medially broader on the left side.
