Northern Pinocchio Treefrog
|Species Description: Oliver PM, R Günther, Mumpuni, and SJ Richards. 2019. Systematics of New Guinea treefrogs (Litoria: Pelodryadidae) with erectile rostral spikes: an extended description of Litoria pronimia and a new species from the Foja Mountains. Zootaxa 4604: 335-348.|
Taxonomic Notes: Following the Australian Society of Herpetology, AmphibiaWeb uses Litoria instead of Ranoidea or Dryopsophus (contrary to Dubois and Fretey 2016 and Duellman et al 2016).
Litoria pinocchio can be set apart from all except for four other Melanesian Litoria by male L. pinocchio have an erectile rostral spike that is at least 2.5 mm in length and the species generally has a relatively slim body, big eyes and relatively small tympana. Litoria pinocchio can be differentiated from the remaining four taxa by the following ways: Compared to L. mareku, L. pinocchio is larger in size, has rostral spikes in males that are longer than it is wide, and has light to medium brown dorsum; Compared to L. havina, L. pinocchio is green and brown and has orange coloration in their groin; Compared to L. murco, they have relatively shorter legs and bigger eyes; Compared to L. pronimia, which is the species that they share the most size and appearance characteristics with, they have shorter limbs, wider tympanum, and differences in coloration (Oliver et al. 2019).
Live L. pinocchio have dorsums that are light brown with some green and dark brown bands, flecking, and spotting. The rostral spike is green. The circular tubercles on the sides of their torso are green. The ventrum and the hidden parts of its thighs and axilla are yellow-orange. The webbing is opaque on both the fingers and toes. Their nuptial pads are brown. When preserved, the dorsal surfaces become light olive green and the transverse blotches on the dorsum are bluish-green. The rostral spike becomes blue and the venter becomes off-white with brown flecks near the lower jaw (Oliver et al. 2019).
At the time of the species description only one male individual was. As a result, individual variation and sexual dimorphism cannot be assessed. However, it is believed that spikes are only present on males (Oliver et al. 2019).
Distribution and Habitat
Country distribution from AmphibiaWeb's database: Indonesia
Life History, Abundance, Activity, and Special Behaviors
Male Pinocchio frogs inflate their nose tip upward when calling (Oliver et al. 2019).
It is assumed that adult Pinocchio frog’s diet primarily consists of insects. Predators of treefrogs, like the Pinocchio frog, include snakes, birds, carnivorous mammals, and fish (Smith et al. 2003).
Trends and Threats
The species epithet “pinocchio” is an allusion to the fictional character created by Carlo Collodi, Pinocchio, whose nose grew longer whenever he was stressed or was being dishonest (Oliver et al. 2019).
