PHILAUTUS TINNIENS
(
JERDON, 1853
)
(
FIGS 2
,

,
59A; TABLE
2)
Type material:
Neotype
,
MNHN 1985.0527
, an adult female,
SVL
25.0 mm, from ‘the
South-East
of the
Ooty Lake
,
Udhagamangalam
[“Ootacamund”, “Ooty”]’,
Nilgiri Hills
,
Tamil Nadu
,
India
.
Other material studied:
BNHS 4497, an adult female, from Avalanche; BNHS 4548, an adult female, and BNHS 4495, an adult male, from Udhagamandalam; BNHS 4494, an adult male, from Coonoor; BNHS 4496, an adult male, from Naduvattam (
Table 2
).
Identity:
Presently,
Ixalus punctatus
Anderson, 1871
,
Ixalus montanus
Günther, 1876
, and
Philautus melanensis
Rao, 1937
are considered synonyms of
P. tinniens
(
Bossuyt & Dubois, 2001
)
.
As already noted by
Bossuyt & Dubois (2001)
, specimens at the Natural History Museum, London, from Kudremukh under the nomen
I. montanus
are different from
P. tinniens
from the Nilgiri Hills. We made a detailed examination of the
14 specimens
at the Natural History Museum, London, from Kudremukh under the nomen
I. montanus
, and revealed that they are different in identity from
P. tinniens
and other species described from this region.
Philautus montanus
(
Günther, 1876
)
chiefly differs from
P. tinniens
by its longer snout–vent length, male SVL 29.0 ±
2.3 mm
,
N
= 5; female SVL 35.6 ±
2.6 mm
,
N
= 9 (vs. male SVL 20.5 ± 1.8,
N
= 3; female SVL 26.8 ±
1.6 mm
,
N
= 3), and by flanks and groin yellowish brown (vs. dark brown), apart from other morphometric characters. However, we await fresh collections and DNA analyses before taking a taxonomic decision.

Diagnosis:
Philautus tinniens
can be easily distinguished from known congeners by the following combination of characters: (1) small adult size (male SVL 20.5 ±
1.8 mm
,
N
= 3; female SVL
26.8 mm
±
1.6 mm
,
N
= 3); (2) shank very short; (3) lateral side coarsely granular; (4) flanks and groin dark-brownish black; (5) first two fingers yellow in life, and light-yellowish white in preservation; (6) tibiotarsal articulation reaches below the level of the eye.
Description of the
neotype
:
A detailed description of the
neotype
was published in
Bossuyt & Dubois (2001)
.
direct development and hatching of froglets took place after 19 days.
Remarks:
This species was incorrectly identified as
I.
variabilis
(BMNH 74.4.29.625, SVL 16.0 mm, and BMNH 74.4.29.652, SVL
16.1 mm
) from ‘Malabar’ by
Boulenger (1882)
.
