Derivatio nominis: Name refers to the existence of the thorns in the vesica.

Diagnosis ( Fig. 18): Wingspan 10-12 mm; head brush pale yellowish; antennae: scape with same colouration, flagellum darker; labial palpi on outside brown, on inside paler, second segment bristled; thorax and tegulae pale yellowish, only basally darker; forewings with a brown pattern on pale yellowish ground color. Brown are oblique stripes from base to dorsum, at 1/2 from costa to dorsum and at 3/4 from costa to dorsum; hindwings grey. Sometimes the entire coloration is darker, the stripes do not reach dorsum, the entire forewing is covered by some dark brown scales and the hindwings are grey-brown.

Male genitalia ( Figs 59-61 ): Uncus truncated, gnathos arms fused, apically narrow, with rounded tip; tegumen narrow, rod-shaped, strongly sclerotised; vinculum and saccus sub-triangular; valvae as long as vinculum-saccus, basal third more or less parallel-sided, then costal edge narrower to rounded apex, ventral edge straight; phallus basally rounded, pistol-shaped, vesica with numerous pointed thorns.

Female genitalia: Unknown.

Remarks: Superficially similar to P. autochthones and P. merdella , but the pointed thorns in the vesica of phallus are clear different in comparision to these two species.
