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.
