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.

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
.
Forewing: narrow, light brown, subterminal area dark 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 brown with an indistinct, black discal spot.
Underside: unicolorous brown.
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.
