A New Neosuidasia Species (Sarcoptiformes: Suidasiidae) from The Netherlands: Life Stage Morphology

The family Suidasiidae Hughes (Acari: Sarcoptiformes: Acaroidea) comprises a small but ecologically diverse group of mites. The genus <i>Neosuidasia</i> is currently monotypic, containing only the species <i>Neosuidasia faini</i> Ranganath & ChannaBasavanna. Although this genus exhibits a wide geographic distribution, ontogenetic research into it remains scarce. This study describes a new species, <i>Neosuidasia sjorsvandenbergi</i> sp. nov., found in domestic poultry in the Netherlands and comprehensively presents the morphological changes across all known life stages, including the adult female, male, tritonymph, protonymph, larva, and egg stages. By documenting the developmental changes and setal patterns throughout ontogeny, this study addresses a significant gap in the understanding of suidasiid mite development.
