Abstract
A new genus and species of eupodoid mite is described from leaf litter
of lowland tropical rainforest in Costa Rica. Aethosolenia laselvensis
gen. nov., sp. nov. possesses a combination of morphological characters
which does not match the current definition for any eupodoid family.
The decision to place it in the Eupodidae is discussed and an amended definition
of the family proposed. The new taxon is unique amongst the Acari
in having dorsal idiosomal setae h1 in the form of trichobothria.
Key words: Aethosolenia laselvensis, new genus, new species,
Eupodoidea, Eupodidae, Costa Rica
