Cophixalus hosmeri
Family: Microhylidae
Common names: Rattling Nurseryfrog; Hosmer's Frog
Description: This frog is grey-brown on its back with darker flecks. There is often a /\ shaped mark between the shoulders. A dark streak runs behind each eye and the snout and upper eyelids are dark in many individuals. There is often a light stripe that runs down the spine. The throat, chest and sometimes the belly are dark grey with pale spots. The belly can also be yellowish, as are the thighs. The skin on the back is smooth or slightly granular and the skin on the belly is smooth. The fingers and toes have visible pads and no webbing.
Size: 15 mm
Habitat: This frog lives in montane forests in northern Queensland.
Call: Sounds like 15-17 clicks rapidly repeated and lasting approximately one second. Call available in 
Windows Media or 
Quicktime audio. Recording Copyright © David Stewart.
Similar species: This frog can be distinguished from Cophixalus concinnus by its smaller size and Cophixalus ornatus by its smaller finger and toe pads.
Conservation Information
Suspected threatening processes
- None stated
Population size: An estimate of the total number of adults present in the species entire range is 10001-50000 individuals, or size is unknown but suspected to be large. Factors affecting population size and distribution are unknown or unsubstantiated.
Population trend in Australia over the past 50 years: Population size stable or suspected to be stable or increasing.
Knowledge of population trend in Australia: Not currently monitored.
Population concentration: Not known to concentrate or exist in discrete locations. (e.g. the number of sites in which individuals group together either seasonally, such as breeding sites, or they may occupy discrete habitat patches within the broader landscape, such as discrete water bodies or drainage units.)
Ongoing management activities in Australia: Management mostly related to enforcement of conservation laws.
Reproductive potential for recovery: The average number of eggs deposited per adult female per year is 1-50 eggs/female/year. Minimum age at which females are known or suspected to first reproduce is 2-3 years.
Range size in Australia: The size of the geographic area over which the taxon is distributed: 101-1000 km².
Distribution trend: Area occupied is stable or has increased. (This is an estimate of change in the portion of the total range that is occupied or utilised; it may not equal the change in total range.)
Knowledge of distribution in Australia: Broad range limits or habitat associations are known, but local occurrence cannot be predicted accurately.
