Pollex ( Pollex) crispus View in CoL Fibiger, new species

( Plate 11 View PLATE 11 , figure 7; male genit. plate 21, figure 1)

Material examined.

Holotype: male, Indonesia, Sulawesi N, Dumoga Bone National Park , 12.ii.1985, genit. prep. 4463 M. Fibiger. Coll. BMNH.

Diagnosis.

Imago (external).

Wingspan: 13 mm.

Forewing: narrow, dark brown, terminal area blackish brown.

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

Reniform: distinct, whitish grey, outlined by black.

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

Underside: unicolorous brown.

Male genitalia.

Tegumen: narrow.

Vinculum: short, stout.

Saccus: V-shaped, short.

Fultura superior: Y-shaped with short narrow arms, fused medially with tegumen and ventrally broadly with juxta-anellus plate.

Valve: longer than wide.

Saccus: much longer than wide.

Ampulla: asymmetrical; long, very narrow, curved, especially towards apex, much shorter than pollex, densely setose with long hair-like, inwardly bent setae.

Pollex : asymmetrical; enormously long, upturned, slightly broader subapically, densely setose with long hairlike, inwardly bent setae especially along ventral and outer margin.

Digitus: reduced to a costal, semi-circular, irregular knob.

Juxta-anellus plate: much higher than wide.

Phallus: extremely long and narrow, broadest by ductus ejaculatorius; sharply curved medially and apically; slightly tapered towards apex; coecum long and pointed.

Vesica: unarmed.

Differential diagnosis.

P. ( P.) crispus differs from the other species of the genus by almost all genital features (see under the subgenus), from the related species of Pollex ( Pollex) furca by the much shorter fultura superior, the smoothly curved ampulla, the large pollex, the abortive digitus, and the longer, narrower phallus.

Diagnosis.

Wingspan: 13 mm.

Male genitalia.

Tegumen: narrow.

Vinculum: very short, stout.

Saccus: U-shaped, very short.

Fultura superior: enormously long, reaching far beyond top of tegumen; with a spine-like process apically on each side; ventrally narrowly, fused with juxta-anellus plate.

Valve: much longer than wide.

Saccus: much longer than wide.

Ampulla: asymmetrical; huge, narrow, right ampulla straight, slightly upturned and club-like apically; densely setose with long hair-like, inwardly bent setae; left ampulla mainly fused with pollex; left ampulla and pollex with free, blunt apices.

Pollex : asymmetrical; huge, broad, right pollex straight, slightly upturned apically; densely setose with long hair-like, inwardly bent setae, especially on outer margin; left pollex mainly fused with ampulla; left pollex and ampulla with free, blunt apices.

Digitus: right digitus a small, medially broad, apically pointed process; left digitus like two thin twigs fused together, outer one longer.

Juxta-anellus plate: higher than wide.

Phallus: extremely long and narrow, broadest by ductus ejaculatorius, smoothly curving through 180°, slightly tapered towards apex; coecum relatively short and apically rounded.

Vesica: unarmed.

Differential diagnosis.

P. ( P.) furca resembles P. ( P.) crispus ; the differences are described under P. ( P.) crispus .
