Apterous Phylloxeroidea [Hemiptera, Sternorrhyncha] from Baltic amber

100%

Wegierek P.

nr Suppl.

Aphids are marked by their high polymorphism, but species reported from Baltic amber are known only from one morph. Aphids most frequently observed in Baltic amber belong to the genus Germaraphis HEIE but only apterous morphs and larval forms are aboundant. On the other hand, the genus Mindarus KOCH is known only from alate morphs. Of superfamily Phylloxeroidea (comprising Adelgidae, Elektraphididae and Phylloxeridae) only the extinct family Elektraphididae is known from Baltic amber. Although as many as 10 species have been described, only alate morphs have been reported. In collection of the Museum of the Earth in Warsaw apterous representatives of Adelgidae (Adelges balticus sp. n.) and Phylloxeridae (Acanthochermes longirostris sp. n.) have been found and described.
