This millipede is known from Phang Nga Province in southern Thailand.
The adults observed alive had black bodies, yellow to whitish-yellow extensions along the sides, and yellow legs.
Most individuals studied in Phang Nga Province were found on rock walls near a cave; some were crawling on leaf litter lying on the rock.
In the described adult specimens, antennae stretched over the back reach body ring 8 or 9 in males and ring 6 or 7 in females.
In the described adult males, a long, forked lobe with sharp tips lies between the bases of the fourth pair of legs.
