Bazillozonium Verhoeff, 1935 Sinocybe Loomis, 1942 Brachycybe (Greek for "short head") is a genus of social millipedes with species in the United States and East Asia.

Species in this genus are often referred to as "feather millipedes" due to their shape.

[1] In a rare example of paternal care in invertebrates, males of most species guard the eggs until they hatch.

[1] Individuals attain lengths up to 1 inch (25 mm) and range in color from orange to tan to pink.

Studies of genetic differences suggest the genus originated in California around 50 million years ago.
