Asterophrys is an amphibian genus of the family -mouthed . It includes two species thatare endemic to Papua New Guinea .

description

The tongue is large and completely attached to the floor of the oral cavity. Palatine teeth are missing. The eardrum is invisible. The front and rear feet are not webbed . There are no precoracoid.

The genus can be distinguished from related genera Asterophryinae by some features of the cranial skeleton and the musculature: for example nasals fused and rough (rugos), frontoparietals with a high, thin bone keel in the longitudinal direction ( sagittal ), squamosum thick and rough. With some related genera (tribe Asterophryini) is u. a. the keeled iliac bone .

Both species are compact, bottom-dwelling frogs with warty skin and a head that is very broad in relation to the body.

Occurrence

The genus occurs only in New Guinea . Asterophrys leucopus has so far only been detected from the type locality : Rainforest on Stolle Mountain ( Sandaun Province , Papua New Guinea ). Asterophrys turpicola is more widespread and is also found in disturbed habitats, including human settlements. Another, previously undescribed species probably lives on the Vogelkop Peninsula ( West Papua , Indonesia ).

Systematics

The genus Asterophrys was first described by Johann Jakob von Tschudi in 1838.

Together with the genera Hylophorbus , Mantophryne , Oninia and Xenorhina , it forms a group of closely related species, the Asterophryinini tribe

According to molecular data (based on homologous DNA sequences), the genus Callulops is next related . According to the data, this may even be paraphyletic (some species are more closely related to Asterophrys than to each other), so that the previous systematics based on morphology must be revised.

species

The species of the earlier genus Metamagnusia ( M. marani and M. slateri ) appear here directly in the genus Asterophrys , as do the species of the earlier genus Pseudocallulops ( P. eurydactyla , P. foja and P. pullifer ).
