From the IUCN Red List Species Account:

 

Range Description

This species was described from Mao Son in northern Viet Nam (Bourret 1942). A specimen from Tam Dao was subsequently also attributed to it (Inger et al. 1999). It has also recently been found on Mount Tay Con Linh II, in Cao Bo Commune, Vi Xuyen District, Ha Giang Province (Bain and Truong 2004). Clarification of its relationship with Philautus gryllus and Rhacophorus verrucosus might alter its known range. It has been recorded from 700-1,200m asl.

Habitat and Ecology

Specimens attributed with certainty to this taxon originate from forested mountain areas. This is presumably a species that breeds by direct development.

Population

It is either a rare, localized species, known from two animals collected at Mao Son in 1937 and one at Tam Dao in 1995 or 1996, or it is part of a widely distributed abundant species that is not currently recognized.

Population Trend

unknown

Major Threats

Its type locality has now been reduced to grassland and some secondary forest, which has presumably affected it, as a result of smallholder farming and clear-cutting logging.

Conservation Actions

Resolving the taxonomy of the R. verrucosus and P. gryllus species groups is a priority requirement before conservation actions can be formulated for this species. The population in Tam Dao is within a protected area.

Red List Status

Data Deficient (DD)

Rationale

Listed as Data Deficient in view of continuing doubts as to its taxonomic validity, extent of occurrence, status and ecological requirements.

Taxonomic Notes

The taxonomic identity of this species compared to Philautus gryllus and Rhacophorus verrucosus is not certain, and nor is its allocation to the genus Philautus (Bossuyt and Dubois 2001).
