<p class="Body"><strong>A contribution to the knowledge of the enigmatic Tanaupodidae (Actinotrichida: Trombidiformes, Parasitengona)</strong>—<strong>description of a new species of <em>Lassenia</em> and a new host record</strong></p>

A new tanaupodid mite, Lassenia newelli sp. nov. is described based on a larva parasitising the aphid Myzocallis coryli (Goeze, 1778) (Aphididae) in Scotland, Great Britain. It ninth species of known from larval stage, second host association for genus and first one which specific affiliation both parasite its provided. The finding contributes to taxonomy biology Tanaupodidae have been considered form basal clades Parasitengona. discovery elongate seta dorsal surface tarsus III L. newelli, characteristic also shared by monotypic Amphotrombium, supports hypothesis possible links between tanaupodids amphotrombiids as early derivative taxa parasitengone mites.
