Heterarthrus flavicollis (Gussakovskij, 1947)

Phyllotoma flavicollis Gussakovskij, 1947: 179-181. Syntypes 10♀, 9♂, in ZISP (Lectotype designated below). Type locality: Georgia, Tbilisi.

Type material examined.

Lectotype Phyllotoma flavicollis , here designated: ♀ “DEI-GISHym4753”, "Tbilisi, 1946, iz min na klena, T. Zhizhilashvili", " Phyllotoma flavicollis , sp. nov. ♀ (typus) Gussakovski det. 1947", "Lectotype Phyllotoma flavicollis Gussakovskij, 1947 designated A. Liston 2010" (ZISP). Paralectotype ♂: “DEI-GISHym4754”, same data as lectotype (ZISP). Further paralectotypes in ZISP were not examined.

Other material examined.

Sweden: 6♂, Skåne (see Liston 1993) .

Remarks.

Apart from its darker head, H. flavicollis is very similar to H. cypricus . The slightly different number of antennomeres given in the key as distinguishing these species needs to be checked in a greater number of specimens.

Host plants and biology.

Acer platanoides L. ( Altenhofer and Zombori 1987). Mine starts near leaf centre ( Liston 1995). Cocoon falls from leaf before the leaf falls from tree. Univoltine.

Distribution.

Central Europe, north to southern Sweden ( Taeger et al. 2006), but rarely recorded, and occurrence apparently very local; Georgia ( Gussakovskij 1947).
