Callulops personatus

Callulops personatus is a relatively large species, with males reaching a snout–vent length of 73 mm (2.9 in) and females 71 mm (2.8 in). The head is narrower than the relatively robust body. The snout is truncate. The tympanum is indistinct; the supratympanic fold runs over and behind the tympanum. The finger and the toe tips have grooved terminal discs; no webbing is present. The anterior half of the head is black, contrasting with the reddish brown coloration of the rest of the dorsal surfaces; there are some black dorsal markings that greatly vary in their intensity between individuals. The belly is immaculate white with an orange or gray tint.[3]

Callulops personatus occurs in lowland rainforest, secondary forest, and anthropogenic grassland at elevations of 240–1,000 m (790–3,280 ft) above sea level,[1] perhaps lower.[3] The holotype was collected from the mouth of one-foot deep burrow and was spotted based on its call.[3] Presumably, development is direct (i.e., there is no free-living larval stage[4]). It is a fairly common species that is not experiencing significant threats. Its range includes the Cyclops Nature Reserve.[1]
