| Comment | HabitaT: forest in hilly areas from sea level to at least 700 m in elevation. This species does quite well in disturbed forests and is commonly found on man-made structures. The holotype and paratypes from Kirirom National Park (FMNH 261851–54) were all found during the day (1400–1630 h) on or near the exterior walls of a building on a grassy plateau within open pine forest. FMNH 261851 was found on the branch of a large tree abutting an exterior wall, FMNH 261852 was found beneath a layer. of paint peeling off the exterior wall of the building approximately 2.5 m above the ground, and FMNH 261853–54 were found on the exterior walls. |
| Etymology | The specific epithet tokehos is the Khmer (Cambodian) word used for Ptychozoon. |
