Taxonomy [top]

Kingdom Phylum Class Order Family
ANIMALIA CHORDATA AMPHIBIA ANURA RHACOPHORIDAE

Scientific Name: Philautus maosonensis
Species Authority: Bourret, 1937
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).

Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Peter Paul van Dijk, Nguyen Quang Truong
Reviewer(s): Global Amphibian Assessment Coordinating Team (Simon Stuart, Janice Chanson and Neil Cox)
Justification:
Listed as Data Deficient in view of continuing doubts as to its taxonomic validity, extent of occurrence, status and ecological requirements.

Geographic Range [top]

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.

Population [top]

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

Habitat and Ecology [top]

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.
Systems: Terrestrial

Threats [top]

Major Threat(s): 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 [top]

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.
