Aniulus
Aniulus is a genus of North American millipedes in the family Parajulidae, comprising at least 20 described species. The genus belongs to the order Julida, characterized by cylindrical bodies and typically inhabiting forest floor habitats. Detailed behavioral studies exist for at least one species, Aniulus bollmani, documenting complex courtship and mating behaviors.
Blaniulidae
Thin Snake Millipedes
Blaniulidae is a family of julid millipedes characterized by extremely elongated, slender bodies with length-to-width ratios reaching 30:1. Members possess distinctive ozadenes (odiferous defensive glands) visible as spots on each segment, and may have eyes present or absent depending on species. The family exhibits diverse habitat preferences including leaf litter, soil, caves, and synanthropic environments. Several genera contain troglobitic species restricted to subterranean habitats, while others are widespread across Europe and have been introduced to other continents.
Blaniulus
Blaniulus is a genus of millipedes in the family Blaniulidae, order Julida. The genus was established by Gervais in 1836 and contains multiple species. Members are characterized by their elongated, cylindrical bodies with numerous segments. The genus has been documented across parts of Europe including Germany, Italy, the Czech Republic, and Croatia.
Bollmaniulus
Bollmaniulus is a genus of cylindrical millipedes in the family Parajulidae, order Julida. The genus was established by Verhoeff in 1926 and contains approximately 14 described species distributed primarily in western North America. Members of this genus are small to medium-sized juliform millipedes characterized by their relatively simple gonopod structure compared to related genera.
Californiulus chamberlini
Californiulus chamberlini is a species of millipede in the family Paeromopodidae, native to western North America. It is one of several species within the genus Californiulus, which is endemic to California and adjacent regions. Like other members of its family, it possesses the elongated, cylindrical body form typical of juliform millipedes. The species was described by Brölemann in 1922.
Californiulus euphanus
Californiulus euphanus is a millipede species in the family Paeromopodidae, described by Chamberlin in 1938. It is endemic to the Pacific Northwest of the United States, specifically found in northwestern Oregon and southwestern Washington. As a member of the order Julida, it belongs to a group of cylindrical, burrowing millipedes.
Julus
Julus is a genus of millipedes in the family Julidae, order Julida. First described by Linnaeus in 1758, it is one of the most historically significant millipede genera. Species occur across Eurasia, with documented populations in the Caucasus, Siberia, and Scandinavia. The genus exhibits notable morphological diversity, particularly in male genital structures and gnathochilarium characteristics.
Okeanobates
Okeanobates is a genus of millipedes in the family Okeanobatidae, order Julida. It was established by Verhoeff in 1939 and is the type genus of its family. The genus has been recorded in Japan and the United States, though specific species-level information remains limited.
Okeanobates americanus
A small millipede species in the family Okeanobatidae, described from North America. The family Okeanobatidae is a small group of juliform millipedes with limited documented natural history. The specific epithet 'americanus' indicates its occurrence in the Americas.
Okeanobatidae
Okeanobatidae is a family of millipedes in the order Julida, established by Verhoeff in 1942. The family contains two genera: Okeanobates and Yosidaiulus. Records indicate presence in Japan and the United States, though specific ecological details remain poorly documented.
Orinisobates
Orinisobates is a genus of millipedes in the family Nemasomatidae, order Julida. It was established by Lohmander in 1933. The genus contains multiple species distributed across parts of Eurasia and has been introduced to North America. Members are small to medium-sized juliform millipedes with the elongated cylindrical body form characteristic of the order.
Orinisobates expressus
Orinisobates expressus is a millipede species in the family Nemasomatidae, first described by Chamberlin in 1941. It belongs to the order Julida, a diverse group of cylindrical millipedes. The species has been documented in Alberta, Canada, with approximately 50 iNaturalist observations contributing to its known distribution.
Ptyoiulus impressus
Flocculent Tailed Millipede
Ptyoiulus impressus is a species of millipede in the family Parajulidae, commonly known as the Flocculent Tailed Millipede. It was described by Thomas Say in 1821 and is found in North America. The species belongs to the order Julida, which contains many common cylindrical millipedes. As a member of the Ptyoiulinae subfamily, it shares characteristics with other Parajulidae including relatively elongated bodies and typical juliform morphology.
Uroblaniulus
Uroblaniulus is a genus of millipedes in the family Parajulidae, order Julida. Members of this genus are cylindrical millipedes with two pairs of legs per body segment, characteristic of the class Diplopoda. The genus was established by Attems in 1901 and is classified within the tribe Uroblaniulini. Observations have been recorded in the eastern United States, particularly Vermont.
