Risiocnemis antoniae is a Philippine endemic confined to the east of Mindanao. The species has a very restricted range with an area of occupancy less than 500 km² and it likely to experience a continuing decline is quality and availability of suitable habitat due to mining and logging activities.
|Range Description:||Risiocnemis antoniae is a Philippine endemic species confined to eastern Mindanao, Mindanao Island.|

|Population:||There is no available information concerning the population status of the species. Exploration of several sites between the two areas where records are known did not reveal the presence of the species. It is likely that it has a very narrow area of occupancy (AOO) with a fragmented population.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Based on its congener, the species is probably typical of forest rivulets and springs. It is probably seen perched on leaves and twigs in shaded portions above trickles. It is also possible that this species can be found at waterfalls.|
The locality where Risiocnemis antoniae is recorded is one of the remaining areas with good forest cover in Mindanao. It is also an area where continuous forest destruction has been going on for several years although attempts for conservation of the area are increasing.
The species has a very narrow area of occupancy and a fragmented population, and is therefore at high risk of extinction. Being a forest specialist, probably with strict habitat requirements, places the species in danger extinction in the near future.
The problem of its very narrow area of occupancy is aggravated by rapid increase of settlement of upland areas and conversion of forest habitat to farming land. Recently, mining activity in the known range of the species has expanded significantly. Several small scale and few large company clear forest areas and dug open pit mines in search for precious metals. Mine tailings for some are released directly to creeks and rivers further contaminate downhill habitat.
|Conservation Actions:||No conservation measures for this species are in place.|
