Trichopetalum uncum is a species of millipede in the family Trichopetalidae. It is endemic to Indiana [1] in the United States. [2] [3] [4] [5]
Millipedes are a group of arthropods that are characterised by having two pairs of jointed legs on most body segments; they are known scientifically as the class Diplopoda, the name derived from this feature. Each double-legged segment is a result of two single segments fused together. Most millipedes have very elongated cylindrical or flattened bodies with more than 20 segments, while pill millipedes are shorter and can roll into a tight ball. Although the name "millipede" derives from Latin for "thousand feet", no species was known to have 1,000 or more until the discovery of Eumillipes persephone, which can have over 1,300 legs. There are approximately 12,000 named species classified into 16 orders and around 140 families, making Diplopoda the largest class of myriapods, an arthropod group which also includes centipedes and other multi-legged creatures.
Myriapods are the members of subphylum Myriapoda, containing arthropods such as millipedes and centipedes. The group contains about 13,000 species, all of them terrestrial.
Trichopetalum whitei, common name Luray Caverns blind cave millipede, is a rare troglobitic millipede of the upper Potomac River drainage in four Virginia counties and three West Virginia counties. It has been recorded from 12 caves across this range, including the Luray Caverns where it was first discovered and described.

The greenhouse millipede, also known as the hothouse millipede, short-flange millipede, or garden millipede, is a species of millipede in the family Paradoxosomatidae that has been widely introduced around the world, and is sometimes a pest in greenhouses.
Titanophyllum spiliarum is a species of cave-dwelling millipede in the family Julidae. The only known species of the genus Titanophyllum, it was described in 2011 from specimens discovered in a cave in Greece. It has several unusual characteristics including eyelessness and a small hook on its hind-most body section that may be involved in keeping the animal ‘locked’ when it coils-up defensively.
