Fig. 3

MATERIAL EXAMINED. Russia: Omsk oblast, Omsk, Victory park, Medicago

sp., 23.VII 2015, 1♂, reared from mine (em. 28.VII 2015), gen. slide no. NK-191-

15♂, N. Kirichenko.

DIAGNOSIS. Forewing with basal streak well defined four costal and three dorsal strigulae, the first pair touching but forming an angulated band sometimes interrupted in the middle. This character distinguishes this species from the similar species feeding on Fabaceae – Ph. nigrescentella (Logan, 1851) and Ph. insignitella

(Zeller, 1846), where the first band, always present, is rounded or slightly angulated.

Male genitalia of Ph. medicaginella are simple, symmetrical, whereas the other two species with strongly asymmetrical genitalia, similar to species feeding on Salicaceae .

DISTRIBUTION. Europe: from Belgium and the Netherlands to Ukraine (De

Prins & De Prins, 2017); Russia: Middle Volga and Volga-Don regions (Baryshnikova, 2008), * Omsk oblast; Kazakhstan, Tajikistan, Turkmenistan, Uzbekistan

(Noreika, 1991).

HOST PLANTS. Oligophagous species on Fabaceae . In Europe: Lotus , Ononis ,

Medicago , Melilotus , Trifolium (De Prins & De Prins, 2017; Ellis, 2017), occasionally on Vicia (Szőcs, 1977) . In Siberia the host plant is Medicago sp. according to our observations.
