Material examined . RUSSIA : Krasnodarskiy Territory : Mostovskoy district, Caucasian Nature Reserve, right bank of river Malaya Laba, env. homestead Chernorechje, 600 m a.s.l., 24.v.2014 , D. Zherebilo ( 1 ♂ , KSU). Remarks . In the original description of P. negrobovi , described from the Apsheronskiy district of Krasnodarskiy Territory, the authors indicate that vertical bristles are not prominent. However the study of the above additional specimen, which was collected in 2014 from Mostovskoy district, bears distinct vertical bristles on the occiput. Obviously this feature is variable in the species. In the key to Caucasian species, P. negrobovi is therefore included twice taking into account these differences.
