Diagnosis.

Wingspan: 10–12 mm.

Forewing: narrow, dark brown.

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

Reniform: distinct, whitish grey, outlined by black.

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

Underside: unicolorous dark brown.

Male genitalia.

Tegumen: narrow.

Vinculum: short, stout.

Saccus: U-shaped, short.

Fultura superior: T-shaped with long narrow arms, fused with upper middle part of tegumen and ventrally with juxta-anellus; where three arms meet, a finger-like, ventrally directed, apically bent process arises.

Valve: shorter than wide.

Ampulla: asymmetrical, long, club-like, very broad medially; densely setose with long hair-like setae bent inwards, right ampulla very broad medially.

Pollex : relatively long, finger-like, equally broad throughout; densely setose subapically with long, hair-like setae bent inwards.

Digitus: very long, narrow, tapered, curved, directed ventrally, apically pointed; right digitus very broad medially, almost hooked apically.

Juxta-anellus plate: huge, round, higher than wide.

Phallus: long, straight, slightly tapered and dorsally upturned towards apex; coecum long and narrow.

Vesica: with a large, straight, spine-like cornutus.

Female genitalia.

7 th abdominal segment: heavily sclerotised, asymmetrical.

Anterior apophyses: length 1½ of posterior apophyses.

Position of ostium bursae: ¼ from anterior edge of 7 th segment, displaced to left.

Ostium bursae: heavily sclerotised on ventral side and half of left side.

Antrum: only slightly sclerotised.

Ductus bursae: coils in several loops, membranous, long, twice as long as corpus bursae.

Corpus bursae: elongated, only slightly wider subapically.

Appendix bursae: arising anteriorly from ductus bursae immediately after antrum.

Differential diagnosis.

P.speideli differs from other species by the asymmetrical digitus, subapically curved phallus, and the sclerotisation of the ostium bursae.
