Abstract.—Uda Mäliboda Trail is an unstudied, remarkable forest located in the northwest region 

of Samanala Nature Reserve (SNR) in Sri Lanka’s wet zone. Here we report the first record of D. 

kotagamai from Uda Mäliboda Trail and the lowest elevation records of four highland Rhacophorid 

frogs: Pseudophilautus altoP. asankaiP. femoralis, and Taruga eques. Further, we present results 

of a preliminary study of herpetofaunal diversity in Uda Mäliboda Trail. Thirty-four amphibian (26 

endemic and 19 Threatened) and 59 reptile (32 endemic and 19 Threatened) species were observed. 

This wet zone forest supports high herpetofaunal diversity; however activities such as deforesta-

tion, human encroachment, mining, agriculture, dumping, road construction, and a hydroelectric 

power station threaten the ecology of this biologically diverse forest.

Key words. Amphibians, awareness, conservation, Duttaphrynus, global biodiversity hotspot, Pseudophilautus

Introduction 

Western Ghats and Sri Lanka have collectively been des-

ignated a global biodiversity hotspot (Mittermeier et al. 

2004; Myers et al. 2000). Favorable environmental fac-

tors such as high rainfall, humidity, and a high density 

of undergrowth vegetation in this region have assisted in 

sustaining regional diversity and distinctness (Bossuyt et 

al. 2005; Gunawardene et al. 2007). Sri Lanka comprises 

the smaller portion of the hotspot, with a total land area 

of 65,610 km

2

. Despite its small size, the region has a 



spectacular assemblage of amphibians and reptiles. Re-

cent molecular studies on amphibians (Rhacophorids 

and Caecilians) and Uropeltid snakes have shown that 

Sri Lanka has maintained a fauna distinct from the In-

dian mainland (Bossuyt et al. 2004; Meegaskumbura et 

al. 2002; Pethiyagoda 2005), yet these subregions are 

separated only by about 300 kilometers (direct distance).

Of Sri Lanka’s three major climatic zones (wet, in-

termediate, and dry) the wet zone harbors a significant-

ly high level of herpetofaunal diversity and endemism 

(Bambaradeniya et al. 2003; Senanayake et al. 1977; 

Wijesinghe and Dayawansa 2002). The wet zone receives 

abundant rainfall (annual average 3,000 mm), has con-

siderable forest cover, and maintains favorable humid-

ity and temperatures to support such high herpetofaunal 

diversity. Previous studies have noted that some herpeto-

faunal species as well as the wet zone forests themselves 

are threatened due to a variety of human activities (e.g., 

IUCN-SL and MENR-SL 2007). Many wet zone forests 

have yet to be studied. Uda Mäliboda in the Kegalle dis-

trict (Sabaragamuwa Province) is one such unstudied wet 

zone forest.

Kotagama’s dwarf toad (Duttaphrynus kotagamai

is endemic and Endangered and is one of the rarest 

bufonids in Sri Lanka (De Silva 2009). Originally de-

scribed from the Sinharaja World Heritage Site in 1994 

by Prithiviraj Fernando and Nihal Dayawansa (Fernando 

et al. 1994) this toad is known only from the Kitulgala, 

Massena, Erathna, and Delwala forest areas (Dutta and 

Manamendra-Arachchi 1996; Goonatilake and Goonati-

lake 2001). It favors a few primary lowland rain forests 

in the wet zone with elevations below 1,070 m (IUCN-

SL 2011). According to Manamendra-Arachchi and 

Pethiyagoda (2006) the holophoront (USNM 311595 H) 

has been lost from the National Museum of Natural His-

tory, Washington, D.C. (USA). Herein we describe new 

localities and a range extension for D. kotagamai from 

a lowland rain forest in the northwestern boundary of 

the Samanala Nature Reserve (SNR) and further provide 

a preliminary checklist of herpetofauna from the Uda 

Mäliboda Forest area.

Materials and methods

We used visual encounter survey methods (Crump and 

Scott 1994) to conduct herpetofaunal surveys for a to-

tal of 17 days and nights between 2006 and 2011. Night 

searches  were  performed  using  headlamps  and  flash-

lights. We searched specific microhabitats including un-

derneath stones and decaying logs, inside tree holes, and 

other potential herpetofaunal retreats. Road kills and data 

from animals dispatched by villagers were also used as 

sources of information. Specimens were hand captured, 

photographed, identified using field guides and scientific 

publications (Ashton et al. 1997; De Silva 2009; Dutta 

and Manamendra-Arachchi 1996; Maduwage et al 2009; 

Manamendra-Arachchi et al. 2007; Manamendra-Arach-

chi and Pethiyagoda 2006; Meegaskumbura et al. 2010; 

Somaweera 2006; Somaweera and Somaweera 2009; Vo-

gel and Rooijen 2011; Wickramasinghe et al. 2007a, b), 

and then released back to the original capture site without 

injury. Species nomenclature was based on Frost et al. 

(2006), Kotaki et al. (2010), Sumida et al. (2007), and 

Senaratna (2001), and conservation status was evaluated 

on the IUCN-SL and MENR-SL (2007).



Study area and habitats

The Samanala Nature Reserve (SNR) is one of the larg-

est and most important forest areas for endemic biodiver-

sity in Sri Lanka and is owned by the Central Highlands 

World Heritage Centre (UNESCO 2011). The Study area 

lies between 6°53’01.58’’ N and 80°26’31.18’’ E with 

elevations ranging from 300-700 m (Fig. 1). This forest 

area is part of the Kegalle district in Sabaragamuwa Prov-

ince. Average annual rainfall ranges from 3,000-4,500 

mm and the average annual temperature is 27.9 °C (Fig. 

2). The vegetation of Uda Mäliboda Trail is categorized 

as lowland wet evergreen forest (Gunatilleke and Guna-

tilleke 1990) and is comprised of the following dominant 

genera: DoonaStemonoporusCalophyllumSyzygium



ShoreaDipterocarpusCullenia, and Mesua (Table 1). 

Pilgrims use four main trails annually between Decem-

ber and April to reach Adams Peak to worship. The Uda 

Mäliboda Trail starts from the “Uda Mäliboda village” 

and continues through Madáhinna (Kuruwita trail) via 

Adams Peak (elevation 2,245 m). This is the longest trail 

and is seldom used by pilgrims since it consists of rough 

terrain and narrow foot paths (Karunarathna et al. 2011).

Results and discussion

New record for D. kotagamai

We report the occurrence of the Endangered, rare, and 

endemic D. kotagamai (Fernando and Dayawansa 1994) 

from Uda Mäliboda forest (Uda Mäliboda Trail) in the 

northwest region of the Samanala Nature Reserve (SNR 

= Peak Wilderness Sanctuary). According to Fernando 

et al. (1994), this species is distinguished from other 

Duttaphrynus species known from Sri Lanka and south-

ern India by combination of the following characters: 

prominent parietal ridges on the head; long and narrow 

unlobulated parotoid glands; most areas of the anterior 

back are smooth; warts present on upper flank, supraor-

bital, and parietal ridges; tips of digits and tips of spinous 

warts black; first finger slightly longer than second finger 

(Fernando et al. 1994). Coloration in life is described as: 

orange-brown on dorsal surface mottled with dark brown 

(juveniles dorsal color is light golden); light cross band 

between eyes and distinct dark cross band on forearm, 

forefoot, tarsus, and tibia; less distinct cross band on up-

per arm and femur; lower jaw with alternate dark and 

light markings; ventral surface whitish mottled with dark 

brown, especially over sternum.

Eleven D. kotagamai were encountered during our 

survey. These toads were only found in primary forest 

and absent from human-disturbed areas. Except for one 

specimen, all were found within ~10 m of a small stream. 

(Fig. 3), and all but four individuals were observed at 

night. Three individuals from Uda Mäliboda measured: 

two males SVL 32.6 mm, 35.2 mm, and a female SVL 

38.5 mm. We also found D. kotagamai in another previ-

ously unknown locality on an adjacent mountain in De-

raniyagala in Kegalle district (Table 2). This mountain 

is located about five km north of Uda Mäliboda. There 

are no previous records of D. kotagamai from the Uda 

Mäliboda Trail (SNR; see De Silva 2009; Dutta and 

Manamendra-Arachchi 1996; IUCN-SL 2011; Mana-

mendra-Arachchi and Pethiyagoda 2006; Goonatilake 

and Goonatilake 2001). The Uda Mäliboda locality is 

approximately six km (direct distance) from “Eratne” 

(Kuru river basin), the nearest published location. The 

direct distance between the onymotope and the new loca-

tion is about 80 km. All of these areas have closed cano-

pies with wet and cool habitats (Fig. 4).

Peabotuwage et al.

Based on the infrequent calls heard during our sur-

vey periods this species is presumably rare in Uda Mäli-

boda. It is aggressive when handled and releases a low-

pitched distress call “crick, crick, crick…”. With two 

new locations and a subsequent range extension, we can 

trace the probable distribution of D. kotagamai prior to 

fragmentation. The new locations indicate a larger distri-

bution than previously concluded. As a result of severe 

fragmentation and habitat degradation in the area, local 

extinctions of previous populations have likely occurred 

in the past with current populations known only from a 

few isolated primary forest patches.



Herpetofaunal diversity

During the study we encountered 34 amphibian species 

representing 15 genera and seven families (Table 3). 

Among those genera AdenomusLankanectesNannoph-



rys, and Taruga are endemic to Sri Lanka. Our results 

show that at least 31% of Sri Lanka’s extant amphib-

ians occur in the Uda Mäliboda area (Fig. 5). Twenty-

six of the 34 species encountered (76%) are endemic, 

five (14%) are considered Near Threatened, four (11%) 

are Vulnerable, and ten (29%) are classified as Endan-

gered (IUCN-SL and MENR-SL 2007). Families with 

the greatest number of endemic species include Rhaco-

phoridae (16 species) and Dicroglossidae (six species), 

while the family Ichthyophiidae, Ranidae (two species 

each) and Nyctibatrachidae (one species) show the low-

est rates of endemism. When considering the 34 species 

by their primary mode of living, 15 (44.1%) were arbo-

real, 10 (29.4%) terrestrial, seven (20.6%) aquatic, and 

two (5.9%) fossorial species.

Most amphibian species observed after brief peri-

ods of rain since many species frequently use temporary 

pools created by these showers. Two large streams course 

forest acting as barriers that restrict some species to par-

ticular habitats. Among the most commonly encountered 

amphibians were Pseudophilautus  folicola, found on 

low growing woody vegetation near water bodies under 

closed canopy, and Fejervarya  kirtisinghei, occurred 

near water bodies lacking canopy. Four Endangered and 

endemic highland species: P. alto (1,890-2,135 m eleva-

tion),  P.  asankai (810-1,830 m), P.  femoralis (1,600-

2,135 m), and Taruga eques (1,750-2,300 m; Manamen-

dra-Arachchi and Pethiyagoda 2006) were encountered 

at this study site, approximately 700 m elevation (lowest 

elevation ever recorded for these species).

We report a range extension for Pseudophilautus 

sarasinorum, an Endangered species previously known 

only from the following localities: Peradeniya (07°16’ 

N, 80°37’ E; Onymotope); Bogawanthalawa-Balangoda 

road (near 25th km post), elevation 1,300 m (06°45’ N, 

80°2’ E); Corbett’s Gap, elevation 1,000 m (07°22’ N, 

80°50’ E); Hunnasgiriya, elevation 367 m (07°23’ N, 

80º41’ E); Agra Arboretum, elevation 1,555 m (06º50’

N, 80º40’ E; Manamendra-Arachchi and Pethiyagoda 

2005). Sumida et al. (2007) suggested the Sri Lankan 

population of F. limnocharis (in Dutta and Manamendra-

Arachchi 1996; Manamendra-Arachchi and Pethiyagoda 

2006) could be F. syhadrensis. However, recent molecu-

lar evidence revealed the Sri Lankan population of F. cf. 



syhadrensis is a separate and unnamed population be-

longing to a unique clade, together with F. granosa and 



F. pierrei (Kotaki et al. 2010). Therefore, we refrain from 

referring to the third Fejervarya species in Sri Lanka 

as F. limnocharis (in Dutta and Manamendra-Arachchi 

1996; Manamendra-Arachchi and Pethiyagoda 2006) 

and instead refer it to as F. cf. syhadrensis.

Fifty-nine species of reptiles representing 37 gen-

era from 11 families were recorded during these surveys 

(Table 4). Among those genera Aspidura,  Balanophis



Ceratophora,  Cercaspis,  Haplocercus,  Lankascincus

Lyriocephalus, and Nessia are considered endemic to 

Sri Lanka. Twenty-eight percent of Sri Lanka’s extant 

reptiles were recorded in the study area (Fig. 5) includ-

ing 28 species of lizards and 31 species of snakes. Of 

these 59 reptile species 32 (54%) are endemic, six (10%) 

Data  Deficient,  ten  (17%)  Near  Threatened,  five  (8%) 

Vulnerable, and four (7%) Endangered (IUCN-SL and 

MENR-SL 2007). Families with the greatest species rep-

resentation include Colubridae (17 species), Scincidae 

(11 species), and Gekkonidae (nine species), while the 

least represented family were Cylindrophidae, Pythoni-

dae, and Typhlopidae (one species each). The highest 

number of endemic species were in the family Scincidae 

(nine species) and Colubridae (seven species), while the 

lowest number were in Cylindrophidae, Elapidae, and 

Typhlopidae (one species each). When considering the 

59 species by  primary mode of living: 24 (40.7%) were 

terrestrial, 21 (35.6%) arboreal, 11 (18.6%) fossorial, and 

three (5.1%) aquatic species.

Among the reptiles, Otocryptis wiegmanniLankas-



cincus greeriDendrelaphis schokari, and Hypnale zara 

were the most commonly encountered species in and 

around footpaths. One unidentified species from the ge-

nus Cyrtodactylus was recorded during this survey and 

may be new to science. Several species of lizards (Cne-

maspis scalpensisC. silvulaHemiphyllodactylus typus

Eutropis beddomii, and Varanus bengalensis) and snakes 

(Boiga beddomeiCercaspis carinatusHaplocercus cey-



lonensis,  Aspidura guentheri,  Balanophis ceylonensis

and  Typhlops mirus) are noteworthy records. The Uda 

Mäliboda forest area also supports three highly venom-

ous snakes: Bungarus ceylonicus (Sri Lanka krait), Da-



boia russelii (Russell’s viper), and Naja naja (Indian co-

bra). Hence, both venomous and non-venomous snakes 

are frequently killed in this area due to fear and igno-

rance as a precautionary measure against snakebites. We 

failed to record any turtle species in the area, possibly 

due to low water temperatures in streams.

Threats and conservation

We believe the high diversity in wet zone forest habitats 

is due mainly to availability of abundant suitable micro-

habitat features (e.g., tree holes, caves, tree barks, rock 

boulders, crevices, water holes, decaying logs, loose soil, 

and other small niches) which create favorable environ-

mental conditions for herpetofauna. According to our re-

sults, Uda Mäliboda area has a rich herpetofaunal diver-

sity and endemism compared with other wet zone forests 

in Sri Lanka. A large number of people including tourists, 

devotees, and laborers annually visit Adams Peak via 

Uda Mäliboda Trail located within the SNR. As a result 

endemic and Threatened species, like many other fauna, 

are seriously affected by increasing pressure caused by 

habitat loss and degradation in montane forests, lower 

montane forests, and marshes. Major threats identified in-

clude illegal timber harvesting, illegal human encroach-

ment, slash and burn forest clearing for human settlement 

and monoculture plantations (especially for tea cultiva-

tion), and gem mining. According to interviews with il-

legal timber harvesters, some rare tree species may be 

new to science are being harvested. Therefore, a further 

comprehensive study of flora is recommended.

Present human activities, the most severe being the 

construction of a hydroelectric power plant, continue to 

degrade and erode the remaining vestiges of this lush pri-

mary forest. Additionally, garbage (polythene) disposal 

along the Uda Mäliboda Trail by visitors and devotees is 

a threat that must be duly monitored by the Department 

of Wildlife Conservation (DWC) and the Forest Depart-

ment (FD) of Sri Lanka. The Young Zoologists’ Associa-

tion (YZA) together with the Central Environmental Au-

thority (CEA) has conducted annual polythene removal 

programs on other trail (Hatton) of SNR for the past 10 

years. This has prompted other Government institutions 

and non-governmental organizations to engage in similar 

activities. We recommend that such programs be initiated 

on this trail in order to prevent further degradation of this 

lush forest.

Some human-altered landscapes such as tea planta-

tions and PinusEucalyptusCyprus, and Casuarina for-

est plantations are located in the foothills of the SNR. 

Most of these altered landscapes can be found up to 

about 800 m in elevation. There is an ongoing hydroelec-

tric power plant development project in the study area 

(Fig. 6) and increased road traffic further threatens the 

area’s fauna. Since a considerable area of the forest is 

altered by human activity, herpetofauna face increased 

threats because, in general, they are often highly sensi-

tive to even slight environmental changes (e.g., McCal-

lum 2007; Pough et al. 2004; Spellerberg 1991). Thus, 

the  identification  and  designation  of  forest  reserves  on 

the perimeter of the SNR could function as suitable buf-

fer zones. Additionally, public awareness programs are 

needed to help guide local people and policy makers de-

Peabotuwage et al.

velop agendas that consider the importance of herpeto-

fauna in maintaining a balanced and healthy ecosystem.

There is no doubt that SNR provides habitat for a 

high number of amphibian and reptiles species (many 

endemic  and  Threatened).  We  affirm  that  it  is  one  of 

the most important herpetofaunal diversity areas in Sri 

Lanka, especially when considering the future conserva-

tion of endemic and threatened herpetofauna. Sri Lanka 

is known as an important herpetofaunal global hotspot 

(Bossuyt et al. 2004; Gunawardene et al. 2007; Meegas-

kumbura et al. 2002; Pethiyagoda 2005) and harbors an 

unusually high number of endemic species. Therefore, 

scientists and policy makers are strongly encouraged to 

make efforts conducting further research on other fau-

nal groups, vegetation, and the forest’s ecosystem as a 

whole. Furthermore, preserving the valuable herpetofau-

nal resources of the Uda Mäliboda Trail is paramount to 

the conservation of global biological diversity.

Acknowledgments.—We would like to express our 

sincere gratitude to Thasun Amarasinghe (Taprobanica) 

for reviewing the earlier draft of the manuscript. We 

also thank Mendis Wickramasinghe (HFS), Aruna Ka-
