Campodea
two-pronged bristletails
Campodea is a genus of small, white, ancestrally wingless hexapods in the order Diplura, commonly called two-pronged bristletails. The genus contains at least 130 described species, with Campodea staphylinus being the most widely known and studied. These blind soil-dwelling arthropods possess remarkable regenerative capacity for lost appendages, including their long antennae. As sister group to Insecta (sensu stricto), Campodea serves as a key reference taxon for understanding early hexapod evolution and the genomic origins of insect innovations.
Evalljapyx anomobris
Evalljapyx anomobris is a species of forceps-tailed dipluran described by Smith in 1960. It belongs to the family Japygidae, a group of small, eyeless, soil-dwelling hexapods characterized by their pincer-like cerci. The species is known from North America, though specific details about its biology remain poorly documented due to the cryptic habits of diplurans and limited research attention to this group.
Evalljapyx hubbardi
forcepstail
Evalljapyx hubbardi is a species of forcepstail, a group of small, soil-dwelling arthropods in the class Diplura. Forcepstails are characterized by their distinctive pincer-like cerci at the posterior end of the abdomen. The species belongs to the family Evalljapygidae, which was historically placed within Japygidae. It has been documented in North America.
Haplocampa
two-pronged bristletails
Haplocampa is a genus of two-pronged bristletails (Diplura: Campodeidae) established by Silvestri in 1912. The genus contains at least five described species, including four named by Silvestri in 1912 and 1933, and one described in 2019 from Vancouver Island, Canada. Species in this genus exhibit varying degrees of cave adaptation, with some showing only slight morphological modification for subterranean life. The genus demonstrates biogeographic connections across the North Pacific, with close affinities to Pacificampa (Japan/Korea), Metriocampa (Siberia), and Eumesocampa (North America), suggesting historical dispersal via the Bering Land Bridge.
Japygidae
forcepstails, japygids
Japygidae is a family of hexapods in the order Diplura, commonly known as forcepstails or japygids. The family is distinguished by unsegmented, hardened, pincer-like cerci at the abdomen tip, which function in prey capture. It comprises approximately 70 genera arranged in seven subfamilies. Japygidae belongs to the superfamily Japygoidea and is sister to Evalljapygidae based on mitochondrial phylogenomic analysis.
Procampodeidae
Procampodeidae is a family of two-pronged bristletails in the order Diplura, class Entognatha. Members of this family are small, soil-dwelling hexapods with reduced or absent eyes and characteristic paired caudal appendages. The family was established by Silvestri in 1948 and belongs to the suborder Rhabdura. Procampodeidae represents one of several families within the campodeoid lineage of diplurans.
