Verhoeff, 1938
Californiulus dorsovittatus is a of cylindrical in the Paeromopodidae, to California. The specific epithet "dorsovittatus" refers to a stripe or band, a distinctive feature of this species. Like other members of the order Julida, it possesses a smooth, rounded body with relatively short legs compared to body length. The Californiulus is restricted to western North America.

Identification
Distinguished from other Californiulus by the stripe indicated by its specific epithet. The combination of smooth cylindrical body, short legs, and California distribution separates it from flat-backed millipedes (Polydesmida) and other orders. Within Paeromopodidae, identification to species level requires examination of male . The dorsal vitta pattern is a key visual characteristic for field recognition.
Appearance
A cylindrical juliform with a smooth, polished . The name "dorsovittatus" indicates the presence of a vitta (longitudinal stripe or band) running along the back. Body coloration is generally dark with contrasting lighter markings. are relatively short and clubbed. Males possess modified (copulatory appendages) on the seventh body segment, characteristic of the order Julida.
Habitat
Known from California; specific microhabitat preferences not documented. As a julid , likely inhabits moist terrestrial environments including forest litter, soil, and decaying wood.
Distribution
to California, United States. Distribution records indicate presence in the state, though precise range boundaries are not well documented.
Ecological Role
As a detritivorous , contributes to decomposition of organic matter and nutrient cycling in soil . Serves as a food source for various and vertebrate .
Human Relevance
No documented direct interactions with humans. Like most native millipedes, plays a background role in health without significant economic or medical importance.
