title: [An aphasmid nematode in the ear capillaries of the reindeer, Lappnema auria n. gen., n. sp. (Robertdollfusidae)].
abstract: Lappnema auris n. gen., n. sp. induces the formation of large nodules on the ears of reindeer, Rangifer tarandus, in Finland; it occurs in subcutaneous capillaries of this organ. The morphology is degenerate. Females are viviparous, 5-6 mm long and 20-25 micrometers wide; infective larvae are almost 2 mm long and 10 micrometers wide. Males are unknown and spermatozoa have not been observed; parthogenetic reproduction seems likely. The genus is similar to Durikainema macropi Spratt and Speare, 1982, the only other aphasmidian from blood vessels and a parasite of marsupials in Australia.
