Guides
Pseudopolydesmus collinus
Rolling Hills Flat-back
Pseudopolydesmus collinus is a flat-backed millipede in the family Polydesmidae, described by Hoffman in 1974. It belongs to the order Polydesmida, characterized by their dorsoventrally flattened bodies. The species is known from limited records in Virginia, United States. As with other members of its genus, it likely inhabits moist forest floor environments typical of polydesmid millipedes.
Pseudopolydesmus paludicolus
Pseudopolydesmus paludicolus is a species of flat-backed millipede in the family Polydesmidae, described by Hoffman in 1950. It belongs to a genus characterized by a flattened body form typical of polydesmidan millipedes. The species epithet 'paludicolus' (from Latin 'palus' meaning marsh and 'cola' meaning dweller) suggests association with wetland or marshy habitats. Documentation of this species remains limited, with few published records beyond original description.
Pseudopolydesmus pinetorum
A small polydesmid millipede species first described by Bollman in 1888. The species name 'pinetorum' refers to its association with pine forest habitats. A laboratory study has documented aspects of its reproduction and growth, though detailed natural history information remains limited.
Pseudopolydesmus serratus
Common Pink Flat-back
Pseudopolydesmus serratus is a species of flat-backed millipede in the family Polydesmidae, commonly known as the Common Pink Flat-back. It was first described by Thomas Say in 1821 and is widely distributed across North America. The species has been the subject of recent morphological research using 3D imaging techniques to study its anatomy and genitalia development.
Scytonotus
Scytonotus is a genus of flat-backed millipedes in the family Polydesmidae, containing approximately 17 described species. The genus was established by C.L. Koch in 1847. Members of this genus are part of the diverse order Polydesmida, which includes millipedes with flattened bodies and lateral extensions of their dorsal plates (paranota). Species in this genus are poorly documented in scientific literature, with limited ecological and behavioral data available.
Scytonotus granulatus
granulated millipede
Scytonotus granulatus, commonly known as the granulated millipede, is a species of flat-backed millipede in the family Polydesmidae. It is native to North America and was first described by Thomas Say in 1821 under the basionym Polydesmus granulatus. As a member of the Polydesmida order, it exhibits the characteristic flattened body form typical of flat-backed millipedes.
