<strong>Near</strong> <strong>Threatened</strong> <strong>Amphibian</strong> <strong>Species</strong> 625lives in closed-canopy forests, and breeding occurs in small, clear, rocky streams. The main threat to this species isclearance of its forest habitat. It is found in several large parks in Sabah, Sarawak and east Kalimantan.Bibliography: Dubois, A. (1987), Inger, R.F. and Stuebing, R.B. (1997), Inger, R.F., Stuebing, R.B. and Tan, F.-L. (1995), Malkmus, R. etal. (2002), Matsui, M. (1997)Data Providers: Robert Inger, Indraneil Das, Robert Stuebing, Maklarin Lakim, Paul YambunLeptolalax gracilis (Günther, 1872)This species has been recorded mainly from Borneo, where there are records from Sarawak (Malaysia), Kalimantan(Indonesia) and Brunei Darussalam. In peninsular Malaysia, records from two mountain peaks (Gunung Tahan andGunung Benom) have been assigned to this species (Grandison 1972; Berry 1975). In Peninsular Thailand there arerecords from Thong Pha Phum Forest, in Kanchanaburi Province, but these require verification. It probably occurs morewidely on Borneo than current records suggest. It has an altitudinal range of 150 to above 1,500m asl. In Borneo itappears to be abundant at some sites in some years and much less common in others, while in Peninsular Malaysiait appears to be an uncommon species. It is confined to primary and old secondary rainforests. Adults and juvenileslive in the floor litter and in the herb and shrub strata. Breeding occurs in streams with clear water and sandy to rockybottoms. Larvae live amid the rocks on the bottom of the watercourse. Deforestation is the principal threat to thisspecies, while siltation of streams following deforestation is a threat to the larval habitat. In mainland SoutheastAsia one population is securely protected in Taman Negara National Park, and this species is also found in at leastthree protected areas in Borneo.Taxonomy: Dubois (1983) suggested that the Peninsular Malaysian populations might be taxonomically distinct from Bornean Leptolalaxgracilis.Bibliography: Berry, P.Y. (1975), Dubois, A. (1983), Grandison, A.C.G. (1972a), Inger, R.F. and Stuebing, R.B. (1997)Data Providers: Peter Paul van Dijk, Robert Inger, Jeet Sukumaran, Yodchaiy ChuaynkernLeptolalax maurus Inger, Lakim, Biun and Yambun, 1997This species is currently known only from Gunung Kinabalu, Borneo, at 1,850m asl. There is no information on its populationstatus. All known specimens were found on the ground in montane forest (oak-chestnut); breeding presumably takesplace in streams. There are currently no major threats to this species. It is found in Gunung Kinabalu National Park.Bibliography: Inger, R.F et al. (1997), Inger, R.F. and Stuebing, R.B. (1997), Malkmus, R.

(2002)Data Providers: Robert Inger, Indraneil Das, Robert Stuebing, Maklarin Lakim, Paul YambunMegophrys kobayashiiMatsui and Malkmus, 1997KOBAYASHI’S HORNED FROGThis species is restricted to Gunung Kinabalu National Park, the Crocker Range, and Mount Trus Madi, Borneo,from 1,300-1,600m asl. It is recorded infrequently. It is a terrestrial species of montane forests, and breeding takesplace in small forest streams. There are currently no major threats to this species. All known populations are withinprotected areas.Bibliography: Malkmus, R. et al. (2002), Malkmus, R. and Matsui, M. (1997)Data Providers: Robert Inger, Djoko Iskandar, Indraneil Das, Robert Stuebing, Maklarin Lakim, Paul YambunOreolalax lichuanensis Hu and Fei, 1979This species is known from Sichuan, Hubei, Hunan, Guizhou and Chongqing Provinces in central China, from 1,790-2,300m asl. It is uncommon. It occurs in forest and shrubland habitat, and breeding takes place in small, shallowgradientstreams. The major threats to this species are very rapid habitat destruction and degradation, through loggingin particular. Its range overlaps several protected areas.Bibliography: Fei, L. et al. (1999), Liu, C.-C., Hu, S.-Q. and Fei, L. (1979), MacKinnon, J. et al. (1996)Data Providers: Fei Liang, Ye ChangyuanOreolalax rugosus (Liu, 1943)This species is known from southern Sichuan and northern Yunnan Provinces, China, from 1,800-3,300m asl. It appearsto have a small population. It inhabits riparian habitats, and breeds in small- to medium-sized hill streams. The majorthreats to this species are habitat destruction and degradation due to clear-felling and agricultural expansion. Therange of this species overlaps with several protected areas.Bibliography: Fei, L. et al. (1999), Liu, C.C. (1943), MacKinnon, J. et al.

(1993)Data Providers: Fei Liang, Wu GuanfuOreolalax schmidti (Liu, 1947)This species is endemic to central Sichuan Province in China, and occurs from 1,700-2,520m asl. It is known fromonly seven or eight locations and its population appears to be small. It occurs in shrublands and coniferous forest,and breeding takes place in small streams and marshes. Habitat destruction and degradation are possible threats tothis species. Its range overlaps several protected areas.Bibliography: Fei, L. et al. (1999), Inger, R.F. et al. (1990), Liu, C.C.

(1996), The Comprehensive ScientificExpedition to the Qinghai-Xizang Plateau (1997)Data Providers: Xie Feng, Wu GuanfuVibrissaphora ailaonica Yang, Chen and Ma, 1983This species is restricted to Ailaoshan and Wuliangshan in central Yunnan Province, China, from 800-2,600m asl. Itis rare and difficult to find. It inhabits evergreen broadleaf forests and breeds in slow-flowing streams. Its habitat iswell protected, and it is not facing any known threats. The entire known range of this species is within Ailaoshanand Wuliangshan National Nature Reserves.Bibliography: MacKinnon, J. et al. (1996), Yang, D.-T. (1991b), Yang, D.-T. et al.

There are no estimates of the status of its subpopulations but it does not appear to be abundant. It is restricted tomontane forests, where adults and juveniles have been found in leaf-litter on the forest floor. Breeding is thought totake place in slow-flowing regions of clear, rocky streams. There are no major threats to this species. The two protectedareas in which it is found, namely Gunung Kinabalu and Tama Negara National Parks, are well protected.Bibliography: Inger, R.F. and Stuebing, R.B. (1997), Malkmus, R. et al. (2002)Data Providers: Robert Inger, Djoko Iskandar, Indraneil Das, Robert Stuebing, Maklarin Lakim, Paul YambunXenophrys dringiInger, Stuebing and Tan, 1995DRING’S HORNED FROGThis species is known only from Gunung Mulu National Park, Borneo, at 1,800m asl, and has not been found inKinabalu National Park despite intensive sampling there, so its range appears to be genuinely restricted. There isvery little information on population status. The only known specimens were found along a small, clear, rocky streamin montane forest. Larvae presumably develop in slow-flowing parts of these streams. There are no major threatsto this species since its habitat is well protected. Continued protection of Gunung Mulu National Park is required toensure the long-term conservation of this species.Bibliography: Inger, R.F. and Stuebing, R.B. (1997), Inger, R.F., Stuebing, R.B. and Tan, F.-L. (1995)Data Providers: Robert Inger, Djoko Iskandar, Indraneil Das, Robert Stuebing, Maklarin Lakim, Paul YambunXenophrys longipes (Boulenger, 1886)This species is only known from the mountain ranges of southern Peninsular Thailand and Peninsular Malaysia, from300-1,000m asl. Records from Cambodia remain unconfirmed. It probably occurs more widely than current recordssuggest. This is an uncommon species even in prime habitat. It inhabits undisturbed evergreen rainforest andmontane moss forest. Larvae live in small, clear, swift-fl owing streams. Some subpopulations might be threatenedby local forest clearance, although overall its montane forest habitat is reasonably secure. It occurs in a numberof protected areas in Thailand, including the Hala-Bala Wildlife Sanctuary, but stronger protection of its habitat inPeninsular Malaysia is required.Taxonomy: Records of Xenophrys longipes from northern Viet Nam (Tran et al. 1992) are provisionally placed under Megophryslateralis; while these animals might represent a taxon distinct from M. lateralis, they are unlikely to be conspecific with X. longipesfrom Peninsular Malaysia.Bibliography: Berry, P.Y.

It is a very rare species. It inhabits forests and streams (in which it breeds). The major threats to this species arehabitat destruction and degradation, arising from smallholder agriculture and dam construction. It is recorded fromat least one protected area, Mangshan National Nature Reserve.Bibliography: Fei, L. et al. (1999), Fei, L., Ye, C.Y. and Huang Y. Z. (1990), MacKinnon, J. et al. (1996)Data Providers: Michael Wai Neng Lau, Bosco ChanXenophrys omeimontis (Liu, 1950)OMEI HORNED TOADThis species is known from six locations in southern Sichuan, China, from 700-1,500m asl. Records tentatively referredto this species were reported from Fan Si Pan Mountain, Lao Cai Province, northern Viet Nam, at 1,400-1,900m asl, byOrlov et al. (2000), but the identity of these records has not yet been confirmed. This is a common species. It inhabitshill streams and forests, and breeding takes place in streams. The habitat of this species is threatened by smallholderfarming activities and tourism. Part of the range of this species falls within protected areas in China. The one locationin Viet Nam from which it has been tentatively recorded is within Hoang Lien Son National Park.Bibliography: Fei, L. et al. (1999), Inger, R.F. et al. (1990), Liu, C.C.

It occurs at high densities. It inhabitsmoist vine forest, and calls from sticks, logs and low vegetation, and from under leaves on the forest fl oor. It appearsto have persisted in areas selectively logged within the past 15 years. Breeding is believed to take place by directdevelopment. The major threat to this species is surface water extraction and resulting changes in flow regimes. Itonly occurs in a small area of state forest (McDonald 1992), which provides protection for its habitat, although thespecies does not occur in a national park.Bibliography: Barker, J., Grigg, G. and Tyler, M.

It has a large population, spread over a moderate area, despitebeing known only from a single location. This species is confined to vine forest within tropical rainforest. It breedsby direct development. The main threat to this species is habitat degradation resulting from tourist activities. Itsrange is within a protected area.Bibliography: Barker, J., Grigg, G. and Tyler, M. (1995), Hoskin C.J. (2004), Zweifel, R.G. (1985)Data Providers: Jean-Marc Hero, Ross Alford, Michael Cunningham, Conrad Hoskin, Keith McDonaldCophixalus exiguus Zweifel and Parker, 1969SCANTY FROGThis Australian endemic is found in a small area south of Cooktown, north-eastern Queensland, where, after a gap of25 years, it was recently collected from Big Tableland, between 555 and 620m asl. It is an abundant species within itsrestricted range. This species is found beneath cover (logs, stones, and leaf-litter) in rainforest comprising vine forest,including areas with Acacia. It calls from beneath leaves and in hollow tree trunks. Breeding takes place by direct development.Threats to this species arise mainly from human impacts on the national parks it inhabits, including for example:erosion following human traffic, and development of walking tracks and other tourist facilities. Improved managementof the protected areas in this species’ range is necessary to limit the disturbance caused by tourist activities.
