Dermacentor similis
Western Dog Tick
Dermacentor similis is a recently described hard tick species (2021) previously misidentified as western populations of Dermacentor variabilis. Molecular and morphological analyses confirmed it as a distinct species restricted to western North America. Like its eastern counterpart, it is a three-host tick with significant medical and veterinary importance, though its specific vector competence for pathogens remains under investigation.
Willowsia neonigromaculata
Willowsia neonigromaculata is a cryptic springtail species described in 2021 from the United States. It was previously confused with the European species W. nigromaculata due to morphological similarity. Genetic and morphological analysis revealed it as distinct, with diagnostic characters including the number of inner appendages on the maxillary sublobal plate. The species belongs to the family Entomobryidae, one of the most diverse families of Collembola.
