Description
(Tables 1–7; Figs. 1–6, 10)
Etymology
Etymology. The species is named after the Kadar tribe of Kerala, who live in the Vazhachal forest where the type series was collected. We enjoyed their support and hospitality during amphibian field studies in the region. The specific epithet kadar is treated as an invariable noun in apposition to the generic name.
Materials Examined
India Thavalakuzhipara
Description
Genetic relationship. Phylogenetically, Fejervarya kadar sp. nov. is nested in the Fejervarya rufescens group (Figs. 1–2) of the Western Ghats. The average uncorrected pairwise genetic divergences with other members of the group are: 3.2% (range 2.8–3.9%, N = 7) for 16S, 9.5% (range 9.3–9.7%, N = 5) for COI, and 8.2% (range 8.0–8.4%, N = 5) for Cytb with F. rufescens; and 6.2% (6.2–6.3%, N = 4) for 16S, 12.1% (range 12.0–12.3%, N = 3) for COI, and 13.7% (range 13.6–13.7%, N = 3) for Cytb with F. cepfi sp. nov. (Table 2). For comparison with F. manoharani sp. nov. and F. neilcoxi sp. nov., see ‘Genetic relationship’ section of those species.
Diagnosis
Diagnosis.Fejervarya kadar sp. nov. can be distinguished from known congeners by the following combination of morphological characters: (1) medium male adult size (SVL 31.0– 33.5 mm, N = 3); (2) stout body; (3) snout rounded in dorsal view and obtuse in lateral view; (4) presence of rictal gland at labial commissure of the mouth; (5) eye length shorter than snout length (male EL/SL ratio 88.9–93.3%, N = 3); (6) tympanum diameter less than half of eye length, (male TYD /EL ratio 37.5–40.5%, N = 3); (7) inter upper eyelid width narrower than upper eyelid width (male IUE / UEW ratio 53.1–60.0%, N = 3) and internarial distance (male IUE /IN ratio 63.0–69.2%, N = 3); (8) thigh length nearly equal to shank length (male TL/ SHL ratio 99.3–99.4%, N = 3); (9) prominent shovelshaped inner metatarsal tubercle prominent and small outer metatarsal tubercle; (10) webbing between toes small. Morphological comparison. Based on the overall morphology and comparable body size, Fejervarya kadar sp. nov. could be confused with the known species F. rufescens and three new species F. cepfi sp. nov., F. manoharani sp. nov. and F. neilcoxi sp. nov. However, Fejervarya kadar differs from F. rufescens by its dorsal skin with scattered glandular warts (vs. shagreened to granular); snout obtuse in lateral view (vs. rounded) and rounded in dorsal view (vs. subovoid); tympanum to eye distance relatively longer or nearly equal to tympanum diameter, male TYE 1.2–1.5 mm, TYD 1.5–1.7 mm, TYE/TYD ratio 80.0–93.3%, N = 3 (vs. relatively shorter, male TYE 1.1–1.3 mm, TYD 1.6–2.2 mm, TYE/TYD ratio 50.0–76.5%, N = 6); thigh length shorter than foot length, male TL 14.5–15.4 mm, FOL 15.7–16.1 mm, TL/FOL ratio 92.4–95.7%, N = 3 (vs. nearly equal, male TL 14.7–15.8 mm, FOL 14.8–15.9 mm, TL/FOL ratio 98.0–99.4%, N = 6); and relatively more webbing between toes, male I2 – –2– II2 – – 3–III 2–3 2/3 IV3 2/3– 2V, specifically the fourth toe webbing slightly above the third subarticular tubercle on either side (vs. less, male I2 – –2 II2 – – 3–III 2– 3IV 3– 2V, specifically the fourth toe webbing extending up to the second subarticular tubercle on either side).
Fejervarya kadar differs from F. cepfi by its dorsal skin with relatively more prominent glandular warts (vs. less prominent); snout rounded in dorsal view (vs. subovoid); inter upper eyelid width narrower than upper eyelid width, male IUE 1.7–1.8 mm, UEW 3.0– 3.3 mm, IUE/UEW ratio 53.1–60.0%, N = 3 (vs. nearly equal, male IUE 2.4–2.5 mm, UEW 2.5–2.6 mm, IUE/UEW ratio 96.0–96.2%, N = 2); inter upper eyelid width narrower than internarial distance, male IUE 1.7–1.8 mm, IN 2.6–2.8 mm, IUE/IN ratio 63.0–69.2%, N = 3 (vs. nearly equal, male IUE 2.4–2.5 mm, IN 2.5 mm, IUE/IN ratio 96–100%, N = 2); tympanum diameter less than half of horizontal diameter of eye, male TYD 1.5–1.7 mm, EL 4.0– 4.2 mm, TYD/EL ratio 37.5–40.5%, N = 3 (vs. nearly half, male TYD 1.8 mm, EL 3.4–3.5 mm, TYD/EL ratio 51.4–52.9%, N = 2); horizontal diameter of eye relatively larger compared to snout length, male EL 4.0– 4.2 mm, SL 4.4–4.5 mm, EL/SL ratio 88.9–93.3%, N = 3 (vs. relatively smaller, male EL 3.4–3.5 mm, SL 4.6–4.8 mm, EL/SL ratio 72.9–73.9%, N = 2); thigh length nearly equal to shank length, male TL 14.5–15.4 mm, SHL 14.6–15.5 mm, TL/SHL ratio 99.3–99.4%, N = 3 (vs. shorter, male TL 14.8–15.4 mm, SHL 15.7–16.4 mm, TL/SHL ratio 93.9–94.3%, N = 2); and relatively less webbing between toes, male I2 – –2– II2 – – 3–III 2–3 2/3 IV3 2/3– 2V (vs. more, male I1 +–2– II1 +– 3–III 2– 3IV 3–1 1/ 2V). For differences with Fejervarya manoharani and F. neilcoxi, see ‘morphological comparison’ of those species.

Distribution
Distribution and natural history.Fejervarya kadar sp. nov. is currently known only from its type locality Thavalakuzhipara (Vazhachal forest), south of Palghat gap in the Western Ghats state of Kerala (Fig. 3). The type series was collected from rocky surfaces of an open hill stream with small puddles or narrow water channels flowing down the slopes at the time of collection. The specific site is located inside an evergreen forest patch close to the Thavalakuzhipara tribal colony. Animals were sensitive to movement around them and tried to hide in nearby ground vegetation or grasses when approached. A few male individuals were found calling erratically but breeding activity was not observed. Collections were made in the late evening between 18:00–20:00 hours.
