Zones of contact and (restricted) hybridization are: – I. middle Amur valley, E Siberia (P. majorsensu stricto and P. minor); – II. SW Mongolia, Bulugun valley (major Sektor and bokharensis Sektor of P. majorsensu stricto); – III. Kyrgystan and Kazakhstan (man-made sympatry of major Sektor and bokharensis Sektor of P. majorsensu stricto), – IV. trans-Caspian area of south Turkmenistan and north Iran (major Sektor and bokharensis Sektor of P. majorsensu stricto and P. cinereus). – V. South China and parts of Indochina (P. minor and P. cinereus, hybridization resulting in P. minor ‘commixtus’,full extent of hybridization unknown). – Slightly modified from Päckert et al.
