Lasiopogon bitumineus
Lasiopogon bitumineus is a species of robber fly in the family Asilidae, described by McKnight in 2020 as part of a taxonomic revision of the bivittatus section of the genus Lasiopogon. The species was among 13 new species described from Nearctic populations in a comprehensive phylogenetic and systematic study. As a member of the bivittatus section, it belongs to a morphologically defined group of western Nearctic Lasiopogon species.
Micaria foxi
Micaria foxi is a small ant-like spider in the family Gnaphosidae, first described by Gertsch in 1933. It belongs to the M. rossica/M. foxi species group, which forms a phylogenetic clade sister to M. formicaria. Like other Micaria species, it is distinguished by piriform gland spigots similar in size to major ampullate gland spigots. The species is known from North America, with records from the United States and Canada including Alberta and British Columbia.
Syndemis
Syndemis is a genus of tortrix moths comprising approximately ten described species. It serves as the type genus of the tribe Archipini within the subfamily Tortricinae. A phylogenetic study of California populations has documented ancient speciation patterns associated with relictual host trees, with sex-biased secondary contact obscuring historical divergence.
