MATERIAL EXAMINED. Russia: Novosibirsk oblast, Novosibirsk, Central

Siberian botanical garden RAS, Malus baccata, 1.VII 2016, 2 leaf mines (herbarium,

vol. XV, 2016), 1♀, reared from mine (em. 6.VII 2016), gen. slide no. NK 28(1.1) ♀,

N. Kirichenko; Krasnoyarsk krai, Krasnoyarsk, dacha community “Pobeda”, Malus

sp., 29.VI 2016, 2♂, reared from mine (em. 2-5.VII 2016), gen. slide EA-1- 15♂,

EA-2- 15♂, E. Akulov; Krasnoyarsk, V. M. Krutovsky botanical garden, Malus sp .,

29. VI 2016, 3♂, reared from mine (em. 1-5.VII 2016), E. Akulov.

150μm (4).

DIAGNOSIS. This species was placed in blancardella group, mining Rosaceae

(Triberti, 2007). Forewing pattern is very similar to Ph. blancardella (Fabricius,

1781) and Ph. hostis (Triberti, 2007) and only the genitalia allow separating these species. Male Ph. pyrifoliella can be identified easily by lacking of the basal processes on valvae. Female genitalia are characterized by a projected sterigma forming a truncate cone, extended just beyond the posterior margin of 8th sternum,

very similar to hostis .

DISTRIBUTION. Europe: from Austria to Ukraine (De Prins & De Prins,

2017); Russia: European central, European Central Chernozem, Middle Volga and

Volga-Don regions (Baryshnikova, 2008), * Novosibirsk oblast, * Krasnoyarsk krai.

HOST PLANTS. Typically monophagous species on Malus (Rosaceae) . In

Europe: Malus sp. , M. domestica , M. sylvestris , occasionally Pyrus communis (De

Prins & De Prins, 2017). In Siberia the host plant is Malus sp. and M. baccata according to our observations.
