First records of moss-feeding aphids (Hemiptera: Sternorrhyncha: Aphididae) from Hungary

Four species of moss-feeding aphids were captured by Berlese samples collected in Heves county, NE Hungary. These data are establishing the first Hungarian records of moss-dwelling aphids, all the four species and three genera are reported from the country for the first time. Muscaphis (Aspidaphium) eschirichi (Börner, 1939) was yielded from a colony of Palustriella commutata (Hedw.) Ochyra collected from rock in a karst spring outlet, Muscaphis (Muscaphis) musci Börner, 1933 was yielded from colonies of Hypnum cupressiforme Hedw. collected from bark of Quercus pubescens Wild. in an open karst forest, Pseudacaudella rubida (Börner, 1939) was yielded from both of the above mosses, while a Myzodium sp. was yielded from a colony of Hypnum cupressiforme mixed with a single stem of Brachythecium salebrosum (Hoffm. ex F.Weber & D.Mohr) Schimp., collected from bark of dead trunk of Quercus cerris L. in a mixed deciduous forest. All moss species are new host records for the corresponding species. Myzodium sp. explain some distinctive characters different from the only European species of its genus and probably belong to an undescribed species, but we are avoiding of describing it on the basis of the single adult captured. Distinctive morphological and biological characteristics of the Hungarian specimens of the four aphid species are discussed and illustrated. A list of the accompanying taxa yielded from the Berlese samples are listed in a table.
