Trichopetalum lunatum
Crescent Moon Millipede
Trichopetalum lunatum is a surface-dwelling or troglophilic millipede in the family Trichopetalidae, originally described by Harger in 1872. It is one of seven species in the genus Trichopetalum, which is distinguished from the fully troglobiotic genera Zygonopus and Scoterpes by its non-cave-adapted lifestyle. The species is known to produce a sticky secretion from the bases of its segmental setae, possibly serving a defensive function.
