[Herpetology • 2019] Litoria pinocchio • Systematics of New Guinea Treefrogs (Litoria: Pelodrydidae) with Erectile Rostral Spikes: An Extended Description of Litoria pronimia and A New Species from the Foja Mountains


Litoria pinocchio 
Oliver,  Günther, Mumpuni & Richards, 2019

Abstract
A small number of treefrog species (Litoria) from Melanesia are unusual amongst Anura in having distinctive fleshy rostral spikes. Here, we first present an extended description for Litoria pronimia Menzies, a small species that is widespread along the southern edge of the Central Cordillera of New Guinea, and in which males have a long and erectile rostral spike. Second, we describe Litoria pinocchio sp. nov. a new, morphologically similar, yet geographically disjunct species from the Foja Mountains in northern Papua Province, Indonesia. The new species differs from Litoria pronimia in aspects of body shape, proportions and colouration. A review of variation in the size, structure and degree of sexual dimorphism of the rostral spike across different species of Litoria suggests varying function including mate selection and camouflage.

Keywords: Amphibia, Frog, Indonesia, mate selection, rostral ornamentation, sexual dimorphism
