“…This paper adds a further four species to the 52 currently known in the genus Litoria on the New Guinea mainland (Zweifel and Tyler 1982) and brings the total number of amphibian species in the region to over 200. In view o f the area o f land still zoologically unexplored in New Guinea, especially in the western half, one may expect this number to increase considerably.…”

“…Since New Guinea with approximately 200 species o f frogs approaches parts o f South America in its anuran diversity, lack o f reproductive diversity may be because the majority o f frogs in the hill and montane forests are land-breeding microhylids rather than hylids with aquatic tadpoles and so do not compete for egg sites near water (Menzies 1976;Zweifel and Tyler 1982).…”

Systematics of Litoria-Iris (Anura, Hylidae) and Its Allies in New-Guinea and a Note on Sexual Dimorphism in the Group

Four new species (Litoria havina, L. mucro, L. pronimia and L. ollauro), whose morphology and known or assumed breeding behaviour suggest that they are related to Litoria iris, are described. Three of these species show marked sexual dimorphism in that the snout of the male bears a dermal 'spike', whereas the snout of the female is truncate. The anatomy of this structure is described and it is speculated that glands on the snout are involved in olfactory stimulation during courtship.

“…The geologically recent emergence of the Vanuatu Archipelago (2 mya) explains some of the reptile and amphibian faunal discontinuities previously identified in Vanuatu such as the absence of frogs (Platymantis) and elapid (Ogmodon) snakes (Schmidt 1930, Zweifel andTyler 1982). In addition, the absence of Ogmodon and Platymantis from Vanuatu-as well as the presence of Perochirus lizards in Vanuatu-has been suggested to result from the north to south counterclockwise rotational geologic movement of this archipelago (Gibbons 1985).…”

Biogeographic Breaks in Vanuatu, A Nascent Oceanic Archipelago

2010

The study of distinct biogeographic demarcations has played a pivotal role in our understanding processes responsible for patterns of species distributions and, importantly, the role of geologic processes in promoting biotic diversification. Biogeographic barriers such as Wallace's line have been shown to be the result of old geologic processes shaping ancient faunal or floral diversification events. Based on distributions of birds, bats, reptiles, plants, and invertebrates we identify a distinct biogeographic disjunction in Vanuatu, a geologically nascent oceanic archipelago. We discuss mechanisms contributing to this concordant pattern across these disparate taxonomic groups in light of geologic history, ocean currents, vegetation, soil, and bioclimatic data, and propose the name Cheesman's line to indicate the faunal and floral discontinuity between the northern and southern islands of Vanuatu.

“…The reproductive behaviour of most of the about 30 described Oreophryne species is unknown (Menzies, 1976; Zweifel & Tyler, 1982; Price, 1992; Johnston & Richards, 1993). Zweifel (1956) reported that Oreophryne anthonyi deposits its eggs in moist cavities of epiphytic Hydnophytum and both parents may take care of eggs and hatchlings.…”

“…Like all Australopapuan microhylids, members of this subfamily do not have free‐living tadpoles, but their yolky rich terrestrial eggs are deposited in moist, sheltered places and develop directly into froglets. Guarding of eggs and/or of newly hatched froglets by one parent has been observed in several species of the genera Callulops , Xenobatrachus and Hylophorbus (Méhely, 1901; Zweifel & Tyler, 1982; Blum & Menzies, 1988; Bickford, 2004), but there are no reports of froglet transport in this subfamily. I documented juvenile transport by a Callulops species in the Wondiwoi Mountains.…”

Derived reproductive modes in New Guinean anuran amphibians and description of a new species with paternal care in the genus Callulops (Microhylidae)

The diversity, distribution, ecology and reproductive biology of the New Guinean anuran amphibians are still poorly known. Recent fieldwork in the western part of New Guinea (Papua, Province of Indonesia, formerly West Irian or Irian Jaya) has documented many new species and revealed derived reproductive modes in some taxa. These strategies are all associated with the liberation of early developmental stages from permanent water. Litoria cf. havina attach comparatively few eggs on the leaves of shrubs or herbs above the water surface. Larvae of Litoria arfakiana have strongly reduced jaws, and at least some older individuals occupy semiterrestrial habitats. Oreophryne clamata deposits its eggs on leaves c. 2 m above the ground, making it the third species known to have arboreal eggs in this speciose genus. In addition to guarding terrestrial eggs, a male of Oreophryne cf. wapoga transported juveniles on its back. The same behaviour was observed in a species of Callulops (the first case in the subfamily Asterophryinae, family Microhylidae), which is here described as new to science. This new species is closely related to C. eurydactylus and was found in lower montane tropical rainforest at the base of the Wandammen Peninsula. Despite having unusually large terminal discs on the fingers and toes for its genus, it was never found climbing on vegetation. Its terrestrial eggs are probably guarded by the male parent and hatchlings are carried around by the male for some days. Through this paternal care, the offspring have a greater chance of survival than do unattended eggs and froglets, and guarding males have, in this way, a greater genetic fitness than males who do not provide this care. It may be supposed that the latter fact was chiefly responsible for the evolution of paternal care in frogs.
