We collected two female specimens (DHMECN 14423-14424) with body sizes of 21.33 mm up to 22.40 mm and two male specimens (DHMECN 14421-14422) with body sizes of 15.58 mm up to 16.73 mm; the specimens were found on bush, palm and cyclanth leaves between 20 cm and 50 cm from the ground in montane Machay Reserve forests at 2290 m elevation. This species is characterised by having a distinctive pattern of irregular white marks on the black venter, conical tubercles on the upper eyelid, one interorbital tubercle and a row of ulnar and tarsal tubercles.
