The individuals observed at Pha Daeng were found on humid rock walls, with most inside holes or crevices in the rock.
In the described adult specimens, antennae stretched over the back reach body ring 7 or 8 in males and ring 6 in females.
In the described adult males, a broad, thin, roughly trapezoidal lobe lies between the bases of the fourth pair of legs.
