Comments on new synonymy

Polydrusus grandiceps

= P. zurcheri ( Schilsky, 1912) syn. nov The following syntype specimen, fully in accordance with the locality given in the original description (Hadjin-Dagh [= Saimbeyli in Turkey, Adana]), is hereby designated as lectotype of P. (Conocetus) zurcheri :

TURKEY: 1 ♂, Hadjin Dagh As. minor // 6 // Ch. Zurcher // Zurcheri * Schils. // Lectotype Polydrusus (Conocetus) zurcheri ( Schilsky, 1912) des. C. Germann 2016 (MFN).

Variability

Specimens vary from dark brownish with scarce and spotty scales to light brown with denser scales. Freshly emerged specimens (where the mandibular scars are still present; these quickly get lost) show denser standing scales.

Ecology

Collected on or nearby Quercus ithaburensis and Quercus sp. in general (sifted from leaf litter; M. Borer oral comm.), but also from Cedrus sp. ( Cupressaceae ). Lives sympatrically in similar habitats with P. transjordanus sp. nov. Collected from April to July, from sea level up to high montane altitudes.
