Protoresinacarus brevipedis gen. n., sp. n. from Early Cretaceous Burmese amber: the first fossil record of mites of the Family Resinacaridae (Acari: Heterostigmata: Pyemotoidea)

Abstract

A new genus and species of mites, Protoresinacarus brevipedis gen. n., sp. n. (Acari: Heterostigmata: Pyemotoidea), is described from Early Cretaceous Burmese amber. This represents the first fossil record of a member of the family Resinacaridae. It is represented by 21 phoretic females adjacent to an adult mantidfly (Neuroptera: Mantispidae). This is the first record of phoresy of pyemotid mites on members of the insect order Neuroptera. The fossil mites differ from extant members of the family in possessing distinctly shorter legs I, which do not reach beyond the apex of the gnathosoma, and by the long setae v 1, v 2 and c 2.
