MATERIAL EXAMINED. Russia, Novosibirsk oblast, Novosibirsk, Central

Siberian botanical garden SB RAS, Prunus padus , 10.VII 2012, 1 larva from mine,

NK85, N. Kirichenko; the same locality, Prunus virginiana f. ‘Atropurpureum’,

(herbarium, vol. VII, 2012), 1 pupa from mine, NK87, N. Kirichenko; the same locality, Amelanchier sp. , 1.VII 2016, 1 larva from mine, NK-92-16-1, N .

slide no. NK-25- 16♂, N. Kirichenko; the same locality, Sorbus aucuparia , 1. VII

2016, 5 leaf mines (herbarium, vol. XV, 2016), 1♂, reared from mine (em. 8. VII

2016), gen. slide no. NK-114- 16♂, N. Kirichenko.

DIAGNOSIS. This species was placed into the blancardella group (Triberti,

2007). The forewing pattern is very uniform, with four costal and three dorsal white strigulae more or less bordered inwardly with dark brown; a narrow basal streak is present. The nearly symmetry of the basal processes of the valvae in male genitalia makes this species easy to recognize. Sometimes the female genitalia can be confused with Ph. cydoniella ([Denis et Schiffermüller], 1775) in ventral view but in lateral view the small, subcylindrical projection of the sterigma of Ph. sorbi is evident. This projection also resembles with that in Ph. hostis Triberti, 2007 but in this species it is much wider than in Ph. sorbi .

DISTRIBUTION. Europe: widely distributed (De Prins & De Prins, 2017).

Russia: Kolsk, Karelia, European North-Western, European South-Taiga and

European Central regions (Baryshnikova, 2008); *Novosibirsk oblast; Kazakhstan,

Turkmenistan (De Prins & De Prins, 2017).

NOTES. Records of Ph. sorbi in North America (Oregon) on apple (Pottinger &

LeRoux, 1971) are regarded as misidentifications of P. elmaella (Landry & Wagner,

1995).

HOST PLANTS. Oligophagous species on Rosaceae . In Europe: Chaenomeles ,

Cotoneaster , Crataegus , Cydonia , Malus , Prunus , Pyrus , Sorbus spp. (De Prins &

De Prins, 2017; Ellis, 2017). In European part of Russia: Cydonia sp. (Kuznetsov,

1981) and Sorbus aucuparia (Yefremova et al., 2009) . In Siberia according to our observations: Amelanchier sp. (new host), Sorbus aucuparia , Sorbocotoneaster pozdnjakovii (new host), Prunus padus , P. virginiana f. ‘Atropurpureum’ (new host).
