Abstract and Figures

Eight new species of Pseudophilautus (Pseudophilautus bambaradeniyai, P. dayawansai, P. jagathgunawardanai, P. karunarathnai, P. newtonjayawardanei, P. puranappu, P. samarakoon, and P. sirilwijesundarai) were discovered as a result of a survey carried out to study the herpetofaunal diversity with the changes in elevation in the Sripada World Heritage Site (Peak Wilderness), Central Hills of Sri Lanka. Detailed descriptions of new species along with colour photographs and line drawings for each species are provided herein. The new species possess unique morphological characters and are well distinguishable from one another that could be easily identified in the field. The conservation status of all species described here, have been considered Critically Endangered, except for P. newtonjayawardanei, as all the new species are recorded from single locations, and their habitats are under severe threat.

The genus Pseudophilautus consists of 65 known
species currently, all of which are endemic to Sri
Lanka (Manamendra-Arachchi & Pethiyagoda 2005;
Meegaskumbura & Manamendra-Arachchi 2005, 2011;
Meegaskumbura et al. 2007, 2009). These direct
developing rhacophorids (Bossuyt & Dubois 2001;
Meegaskumbura et al. 2002; Bahir et al. 2005; Grosjean
et al. 2008; Li et al. 2008, 2009; Biju & Bossuyt 2009; Yu
et al. 2009) previously belonged to the genus Philautus
which were widely distributed throughout tropical Asia
(Bossuyt & Dubois 2001; Bossuyt et al. 2004; Frost et al.
2006; Yu et al. 2009). But later, considering molecular
phylogenecs, the populaons in Sri Lanka and India
were found to be a separate radiaon belonging to a
separate genus known now as Pseudophilautus (Li et al.
2009; Yu et al. 2010; Meegaskumbura & Manamendra-
Arachchi 2011). The most recent publicaon of this genus
by Meegaskumbura & Manamendra-Arachchi (2011) in
the country described two species which brought the
total number to 65 species. But sadly, a considerable
poron of the total number of idened species, have
already vanished (17 species) (Manamendra-Arachchi &
Pethiyagoda 2005; Meegaskumbura et al. 2007) where
most have not even been sighted aer their inial
descripons, showing an urgency to conserve the few
remaining habitats.
Peak Wilderness as part of the Central Hills was recently
designated as a World Heritage Site. Geographical area
of the sanctuary is about 240sq.km, of which 211.75sq.
km comprises natural or semi natural vegetaon; the
rest is no longer forest and includes tea estates and
village selements. The sanctuary lies in the center
of the western ridge of the Central Highlands, north-
east of Ratnapura and spanning the border of Central
and Sabaragamuwa provinces. Its eastern boundary
is conguous with Horton Plains Naonal Park. Peak
Wilderness occupies the escarpment that rises steeply
from the lowlands to the south and west. Much of the
terrain is very rugged, with altudes ranging from 600m
near Ratnapura to 2,238m at Sripada Peak, Sri Lanka’s
fourth highest peak. It is an important watershed for
three major river systems, the Kelani Ganga, the Kalu
Ganga, and the Walawe Ganga (DWC 2007).
The last vertebrate species discovered from
the studied area were Cnemaspis samanalensis
(Wickramasinghe & Munindradasa 2007); Lankascincus
munindradasai and Lankascincus sripadensis
(Wickramasinghe et al. 2007), depicng its diversity.
Because of relavely high altudes, dicult
trails, heavy rainfall, and steep geographic variaons,
proper eld surveys in this region were lacking. Due
to this reason inspite of the geographical and climac
variaons the region was considered to have a lower
faunal diversity. Hence, we carried out the survey with
the intenon of seng a basis for the actual diversity
of herpetofauna of Peak Wilderness. The novel species
described here from the Peak Wilderness, Central Hills,
of Sri Lanka, as results of the preliminary two phases of
an extensive eld survey of the region which lasted for
a period of two years (end of 2009-end of 2011), were
based on morphological and morphometric characters.
Sripada Peak is the highest point in this mountain range,
and because of its religious importance, and aesthec
beauty, pilgrims and travellers have idened six major
trails leading to the top. For the 1st phase, sampling was
carried out in the trail leading from Palabaddala to the
Sripada peak, and in the 2nd phase we chose Kuruvita to
the Sripada peak. Our work here describes a collecon
of eight new species, with each species having a detailed
descripon based on strong morphological characters,
accompanied by colour photographs.

The approximate total distances of the 1st trail (from
Palabaddala to the Sripada peak) was 10km, and the 2nd
trail (from Kuruvita to the Sripada peak) was 10km. The
eld survey commenced at the end of 2009, and the
Phases I and II were completed in December 2011. The
sampling sites were selected considering the accessibility,
representave habitats and spaal distribuon in the
Naonal Park, through an inial reconnaissance survey.
Fieen eld visits were made, each sampling session
spanning eight connuous days. Sampling was done
mostly nocturnally, and photographs of most species
were done in the wild to avoid any confusion of change
in colour aer capvity and to avoid over collecon of
the same species. Specimens collected in the eld were
rst xed in 90% ethanol for two hours and stored in
70% ethanol.
Sex and maturity were determined by examining
secondary sexual characters, or when absent, by
examining the gonads through a small lateral incision
in the specimen. The following morphological
charactetriscs were common to all eight species hence
they have not been menoned under each species;
nostrils oval, without ap of skin laterally, small, close
to p of snout; latero-dorsal folds, lateral line system,
Fejervarya line, and macroglands were absent. We here

have explained the terminology used to explain the skin
textures, specially the variaons in granular skin on the
ventral side of body: weakly granular (Image 1); granular
(Image 2); coarsely granular (Image 3). The new type
material discussed in this paper is also deposited in
NMSL and the Department of Wildlife Conservaon
(DWC), Naonal Wildlife Research and Training Center,
Girithale, Sri Lanka.
The new species were compared with all types
from Sri Lanka, deposited in the NMSL and specimens
deposited in the Natural History Museum, London
(Appendix 4). The specimens that formerly belonged to
the Wildlife Heritage Trust (WHT) bearing WHT numbers
are currently deposited in the NMSL, catalogued under
the same numbers. For the descripon secon, all
known species of Sri Lanka were grouped into four
categories based on their snout to vent length: very small
(<15mm), small (16–30 mm), moderate (31–45 mm) and
large (46–60 mm). Comparison for each species was
carried out amongst all species belonging to the genus
Pseudophilautus, by cancelling common characters and
taking the best combinaon of characters that best
disnguishes. In the comparison tables for each species,
for convenience of disnguishing the species, an empty
cell in the table denotes either the same character as
that of the species considered, or for few exnct species
when there was no data available. Hence in order to
minimise this error we included all characteriscs and
all species in one table provided in Appendix 1 and 2,
by selecng the best combinaon of characters where
Appendix 1, provides morphological characters that
dierenate Pseudophilautus species and Appendix 2
provides characters in the skin structure that dierenate
Pseudophilautus species. We paid special aenon to
exnct species and their characters in the comparison
(Wickramasinghe et al. 2013) of each species.

characters were taken as %SVL. Principle Component
Analysis (PCA) was performed on the correlaon matrix
between 25 variables using the soware PAST (Hammer
et al. 2001). Dendrogram showing the relaonship
between dierent species was ploed using mean values
of morphometric data for each species using Euclidian
distances and Ward’s method for clustering in PAST.
Geographical coordinates were determined from
GPS readings (Gamin eTrex Gista) with WGS84 (World
Geodec System) datum at the locality. Addional data
for comparison were collected from Pethiyagoda &
Manamendra-Arachchi (2005) and WGS 84 world grid
system.
