PHILAUTUS TINNIENS ( JERDON, 1853) View in CoL
( FIGS 2 View Figure 2 , 58 View Figure 58 , 59A; TABLE View Figure 59 2)
Type material: Neotype, MNHN 1985.0527 About MNHN , 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).
