Comments on new synonymies
Based on all specimens examined and their identical internal sacs (see Fig. 9A–C), P. siculus and P. vodozi are hereby regarded as junior synonyms of P. kahri.
Magnano (1964) resurrected P. siculus from synonymy, mainly based on the differences given by Desbrochers des Loges (1872) in the original description. However, upon examination of specimens from various localities for the present study, these characters do not support a species status, therefore Polydrusus siculus = Polydrusus kahri.
In the case of P. vodozi, the synonymy with P. kahri proposed by Hoffmann (1950) and Schott (2014) is formally approved here (Polydrusus vodozi = Polydrusus kahri). The type specimen in the collection of Desbrochers was examined by L. Schott and confirmed as conspecific with P. kahri; furthermore, a male specimen from Corsica was examined (see below).
Remarks
Polydrusus kahri is a widespread species reported from France (Alpes Maritimes), including Corsica (Vizzavona: Hoffmann 1950; Schott 2014), Austria to Dalmatia, Bosnia-Herzegovina, Macedonia, Montenegro (Yunakov 2013; no specimens presently examined and not included in Fig. 10), Greece, and all of Italy including Sicily, but apparently excluding Sardinia (mentioned by Hoffmann 1950, but not included in Colonnelli 2003, nor in Abbazzi & Maggini 2009). Records by Yunakov (2013) from Cyprus are highly dubious and may refer to misidentifications. Polydrusus kahri shows large variability in size and density of vestiture.
