Aphid species and morphs new to the fauna of Finland (Homoptera, Aphididae, Macrosiphini)

Osmo Heikinheimo

Heikinheimo, 0. 1990: Aphid species and morphs new to the fa un a of Finland (Homoptera, Aphididae, Macrosiphini).- Entomol. Fennica 1:65-98. Collecting data are represented on 26 species and subspecies new to Finland and some morphs are described for the first time. Comments on some species are given and new characters of diagnostic value are described for several species. Acyrthosiphon aurlandicum Heikinheimo, 1966 is a junior synonym of A. brachysiphon Hille Ris Lambers, 1952. A new subgenus, Metobion, with typus subgen. Acyrthosiphon (Metopolophium) graminearum Mordvilko, 1919, is erected in the genus Sitobion Mordvilko, 1914. 0.

Since my latest report on new aphid species from ovip. oviparous female (sexual) Finland was published (Heikinheimo 1984 ), fur­ segm. = segment ther materials have been examined of aphids urs. ultimate rostral segment captured with wind net traps (loc. cit .), suction viv. viviparous female (parthenogenetic) traps or other means. This paper lists 26 taxa of the IIIbd basal diameter of ant. segm. III tribus Macrosiphini which are new for the fauna VIa basal part of ant. segm. VI (up to di stal of Finland. Each record includes the abbreviation margin of primary rhinarium) of the biological province, the name of the munici­ VIb processus terminalis (distal part of ant. pality, the code of the square mile of the uniform segm.

If the collector's name is not mentioned, Index of species, see p. 98. the sample has been collected by the author. The aphid samples include some hithe11o undescribed morphs, for which descriptions are presented.
