 Abstract

The Night Frog genus Nyctibatrachus (Family Nyctibatrachidae) represents an endemic anuran lineage of the Western Ghats Biodiversity Hotspot, India. Until now, it included 28 recognised species, of which more than half were described recently over the last five years. Our amphibian explorations have further revealed the presence of undescribed species of Nights Frogs in the southern Western Ghats. Based on integrated molecular, morphological and bioacoustic evidence, seven new species are formally described here as Nyctibatrachus athirappillyensis sp. nov., Nyctibatrachus manalari sp. nov., Nyctibatrachus pulivijayani sp. nov., Nyctibatrachus radcliffei sp. nov., Nyctibatrachus robinmoorei sp. nov., Nyctibatrachus sabarimalai sp. nov. and Nyctibatrachus webilla sp. nov., thereby bringing the total number of valid Nyctibatrachus species to 35 and increasing the former diversity estimates by a quarter. Detailed morphological descriptions, comparisons with other members of the genus, natural history notes, and genetic relationships inferred from phylogenetic analyses of a mitochondrial dataset are presented for all the new species. Additionally, characteristics of male advertisement calls are described for four new and three previously known species. Among the new species, six are currently known to be geographically restricted to low and mid elevation regions south of Palghat gap in the states of Kerala and Tamil Nadu, and one is probably endemic to high-elevation mountain streams slightly northward of the gap in Tamil Nadu. Interestingly, four new species are also among the smallest known Indian frogs. Hence, our discovery of several new species, particularly of easily overlooked miniaturized forms, reiterates that the known amphibian diversity of the Western Ghats of India still remains underestimated.



• Nyctibatrachus athirappillyensis sp. nov.
 Athirappilly Night Frog

Holotype. ZSI/WGRC/V/A/891, adult male, from Thavalakuzhipara (10°16′53″N 76°41′25.6″E, 530 m), Vazhachal forest division, Thrissur district, Kerala state, India, collected by SDB and SG on 11 September 2015.

Paratypes. ZSI/WGRC/V/A/892–895, four adult males, and ZSI/WGRC/V/A/896, adult female, collected from the same locality as holotype, by SDB and SG on 11 July 2016.

Etymology. The species epithet is an adjective that refers to Athirappilly falls, which is in close vicinity of the type locality.

Distribution and natural history. Nyctibatrachus athirappillyensis is currently known only from its type locality in the southern Western Ghats state of Kerala. All the specimens were collected from shallow streams or marshy areas covered with thick vegetation or leaf litter. Collection site was located inside a secondary forest. Calling males were found hiding under vegetation either inside the shallow stream or on the edges. Calls were heard and recorded during the late evening between 18:00–22:00 h.

Remark. Biju et al. (2011) erroneously interpreted the “fourth toe disc with dorso-terminal groove, cover rounded distally” in Nyctibatrachus kempholeyensis. In the present study we confirm that the fourth toe disc of N. kempholeyensis has a dorso-terminal groove with cover notched distally.


• Nyctibatrachus manalari sp. nov.
 Manalar Night Frog

Holotype. ZSI/WGRC/V/A/897, adult male, from Upper Manalar (09°34′29.31″N 77° 20′10.27″E, 1564 m), Periyar Tiger Reserve, Idukki district, Kerala state, India, collected by SDB and SG on 15 July 2016.

Paratypes. ZSI/WGRC/V/A/898–901, four adult males, collected along with the holotype.

Etymology. The species is named after the type locality Upper Manalar in Periyar Tiger Reserve, from where the type series was collected. The specific name manalari is a noun in the genitive case.

Distribution and natural history. Nyctibatrachus manalari is currently known only from its type locality, which is located south of Palghat gap in the Western Ghats state of Kerala. Animals were found hiding under herbs and grasses growing on or at the edges of a large rocky area inside a primary evergreen forest patch. Calling males were located and recorded at night (between 19:00–21:00 h), but calls were also heard during the day (around 14:00 h). One of the calling males was found next to an egg clutch (eight eggs) deposited under the ground vegetation.


• Nyctibatrachus pulivijayani sp. nov. 
Vijayan’s Night Frog 

Holotype. ZSI/WGRC/V/A/902, adult male, from Pandipath (08°40′42.0″N 77°11′38.6″E, 1,250 m), Thiruvananthapuram district, Kerala state, India, collected by SDB, SG and Vijayan on 19 June 2016.

Paratypes. ZSI/WGRC/V/A/903–905, three adult males collected along with the holotype, and ZSI/WGRC/V/A/906, adult male, collected from the same locality as holotype, by SDB and SG on 29 June 2015.

Etymology. This species is named after Mr. Vijayan Kani for consistently offering tremendous field support over two decades to SDB and his students during studies in the Western Ghats. Vijayan, a tribal from Agasthyamala hills of Kerala, acquired the name ‘Pulivijayan’ after he braved a leopard’s attack. The name is derived from two words; ‘puli’ meaning leopard in Malayalam (official language of Kerala state) and ‘vijayan’. The species epithet ‘pulivijayani’ is used as a noun in the genitive case. The specific word ‘puli’ also refers to leopard-like spots observed on the dorsal surface of this species.

Distribution and natural history. Nyctibatrachus pulivijayani is currently known only from its type locality, which is located in Agasthyamala Hills, south of Palghat gap in the Western Ghats state of Kerala. Animals were found hiding under herbs and grasses on marshy ground (usually away from water) inside an evergreen forest. Males were observed calling during the day (around 11:00 h) and in the late evening (18:00 h).


• Nyctibatrachus radcliffei sp. nov. 
Radcliffe’s Night Frog 

Holotype. ZSI/WGRC/V/A/920, adult male, from Thiashola estate (11°13′48.2″N 76° 37′02.1″E, 1920 m), Nilgiris district, Tamil Nadu state, India, collected by SDB and SG on 09 July 2016.

Paratypes. ZSI/WGRC/V/A/921–922, two adult males, collected along with the holotype, and ZSI/WGRC/V/A/923–924, two adult males, collected from the same locality as holotype, by SDB and SG on 08 July 2016.


Etymology. This species is named after the late Major Richard Radcliffe in recognition of his contribution towards biodiversity conservation in the Nilgiris. The species name radcliffei is a noun in the genitive case.

Distribution and natural history. Nyctibatrachus radcliffei sp. nov. is currently known only from its type locality, which is located in the Nilgiris, north of Palghat gap in the southern Western Ghats state of Tamil Nadu. All the specimens were found in crevices under rocks in a hill stream inside the tea estate. In our study, we observed tadpoles of this species during the month of October 2014 and confirmed their identity using DNA. Since calls or breeding activity was not observed at the time of collection (in July), we presume that this species breeds during the early monsoon period. Collections were made between 20:00–23:00 h.



• Nyctibatrachus robinmoorei sp. nov. 
Robin Moore’s Night Frog 

Holotype. ZSI/WGRC/V/A/925, adult male, from Kakkachi (08°33′02.6″N, 77°23′29.6″E, 1290 m), Tirunelveli district, Tamil Nadu state, India, collected by SDB on 30 August 2002.

Etymology. The species is named for Dr Robin Moore, a wildlife photographer and conservationist, in appreciation of his contribution to amphibian conservation. The species name robinmoorei is considered as a noun in the genitive case.

Distribution and natural history. Nyctibatrachus robinmoorei is currently known only from its type locality, which is located in the Kalakkad Mundanthurai Tiger Reserve, south of Palghat gap in the Western Ghats state of Tamil Nadu. Animals were collected from a marshy area covered with thick ground vegetation, close to a rivulet inside primary forest. Males were heard calling during daytime (12:00–14:00 h) and in the late evening (around 18:00 h).

• Nyctibatrachus sabarimalai sp. nov. 
Sabarimala Night Frog 

Holotype. ZSI/WGRC/V/A/927, adult male, from Pamba (09°24′17.6″N 77°04′11.6″E, 210 m), Pathanamthitta district, Kerala state, India, collected by SDB and SG on 17 July 2016.

Paratypes. ZSI/WGRC/V/A/928–931, four adult males collected along with the holotype, and ZSI/WGRC/V/A/932, adult female, collected from the same locality as holotype, by SDB, SG, RS, SS on 02 July 2015.

Etymology. The species is named after Sabarimala, a pilgrim site located inside the Periyar Tiger Reserve, from the surroundings of which the type series was collected. The species name is considered as a noun in the genitive case.

Distribution and natural history. Nyctibatrachus sabarimalai is currently known only from its type locality, which is located close to Sabarimala in Periyar Tiger Reserve, south of Palghat gap in the Western Ghats state of Kerala. Individuals were located under leaf litter in a shallow forest stream or under the grasses on wet rocky terrain. A calling male was found positioned next to an egg clutch (10 eggs) deposited inside a slit on a tree stump about one foot above ground. Males were observed calling both during the day (between 15:00–17:00 h) and night (20:00–22:00 h).


• Nyctibatrachus webilla sp. nov. 
Kadalar Night Frog 

Holotype. ZSI/WGRC/V/A/933, adult male, from Kadalar (10°07′52.0″N 77°00′01.8″E, 1429 m), Idukki district, Kerala state, India, collected by SDB and SG on 08 June 2016.

Paratypes. ZSI/WGRC/V/A/934, adult male, collected along with the holotype, and ZSI/WGRC/V/A/935–936, two adult males, collected from the same locality as holotype, by SDB and SG on 18 August 2013.

Etymology. The species name is derived from the English term ‘web’ between toes and the Malayalam word ‘illa’, meaning ‘no’— referring to the prominently reduced foot webbing in this species in comparison to its close relative Nyctibatrachus deccanensis. The species name is treated as an invariable noun in apposition to the generic name.

Distribution and natural history. Nyctibatrachus webilla is currently known only from its type locality, which is located south of Palghat gap in the Western Ghats state of Kerala. Animals were found hidden either under leaf litter or vegetation on marshy ground close to a shallow rivulet. The specific collection site was located inside a disturbed forest patch adjacent to tea estate. Males were collected and observed calling both during the day (around 10:00–12:00 h) and night (between 19:00–22:00 h).

[Herpetology • 2017] Description of Four New Species of Burrowing Frogs in the Fejervarya rufescens complex (Dicroglossidae) with Notes on Morphological Affinities of Fejervarya Species in the Western Ghats ---ScRaBBlE


Fejervarya kadarFejervarya manoharani,
Fejervarya neilcoxi Fejervarya cepfi

Garg & Biju, 2017

Abstract

The Rufescent Burrowing Frog, Fejervarya rufescens, is thought to have a wide distribution across the Western Ghats in Peninsular India. This locally abundant but secretive species has a short breeding period, making it a challenging subject for field studies. We sampled 16 populations of frogs morphologically similar to F. rufescens in order to understand the variation among populations found across the Western Ghats. Our study shows significant morphological and genetic differences among the sampled populations, suggesting that F. ‘rufescens’ is a complex of several undescribed species. Using evidence from morphology and genetics, we confirm the presence of five distinct species in this group and formally describe four as new. The new species were delineated using a phylogeny based on three mitochondrial genes (16S, COI and Cytb) and a haplotype network of a nuclear gene (Rag1). Hereafter, the distribution of F. rufescens is restricted to the state of Karnataka and adjoining regions of northern Kerala. Three new species (Fejervarya kadar sp. nov., Fejervarya manoharani sp. nov. and Fejervarya neilcoxi sp. nov.) are from regions south of Palghat gap in the state of Kerala, and one (Fejervarya cepfi sp. nov.) from the northern Western Ghats state of Maharashtra. These findings indicate that Fejervarya frogs of the Western Ghats are more diverse than currently known. Our results will also have implications on the conservation status of F. rufescens, which was previously categorized as Least Concern based on its presumed wide geographical distribution. Furthermore, in order to facilitate a better taxonomic understanding of this region’s fejervaryan frogs, we divide all the known Fejarvarya species of the Western Ghats into four major groups—Fejervarya nilagirica group, Fejervarya rufescens group, Fejervarya sahyadris group and Fejervarya syhadrensis group, based on their morphological affinities.

[Herpetology • 2019] Mysticellus franki • A New Microhylid Frog Genus from Peninsular India with Southeast Asian Affinity Suggests Multiple Cenozoic Biotic Exchanges Between India and Eurasia ---ScRaBBlE


Mysticellus franki
Garg & Biju, 2019


Abstract
Anurans in Peninsular India exhibit close biogeographical links with Gondwana as well as Laurasia, often explainable by the geological history of the Indian subcontinent; its breakup from Gondwanan landmasses followed by long isolation that resulted in diversification of endemic lineages, and subsequent land connections with Asia that enabled dispersal of widespread groups. Although widely distributed, the frog subfamily Microhylinae mostly comprises of geographically restricted genera found either in Southeast and East Asia or Peninsular India and Sri Lanka. Here we report a previously unknown microhylid from the Western Ghats in Peninsular India with closest relatives found over 2,000 km away in Southeast Asia. Based on integrated evidence from mitochondrial and nuclear DNA, adult and tadpole morphology, hand musculature, male advertisement call, and geographical distance, we recognize this enigmatic frog as a distinct new species and genus endemic to the Western Ghats. The discovery of Mysticellus franki gen. et sp. nov. and its close evolutionary relationship with the Southeast Asian genus Micryletta also provide insights on the biogeography of Microhylinae. Genus-level divergences within the subfamily suggest multiple Cenozoic biotic exchange events between India and Eurasia, particularly through postulated Eocene land bridges via Southeast Asia prior to accretion of the two landmasses.

Microhylidae Günther, 1858 (1843)
Microhylinae Günther, 1858 (1843)

Mysticellus gen. nov.

Type species: Mysticellus franki sp. nov.

Etymology: The genus name, Mysticellus, is a masculine noun derived from the Latin mysticus (meaning mysterious) + ellus (a diminuitive), highlighting the ability of this small frog to remain out of sight despite its occurrence in wayside areas surrounding human settlements.

Suggested common name: Mysterious Narrow-mouthed Frog.

Diagnosis: The new genus Mysticellus differs from other Microhylinae genera by the combination of following characters: small adult snout-vent size (male SVL 23.0–27.5 mm, N = 5; female SVL 27.0–28.9 mm, N = 2), slender body; snout longer than eye length, male SL 2.8–3.0 mm, 2.9 ± 0.1 mm, N = 5, female SL 3.0–3.2 mm, 3.1 ± 0.1 mm, N = 2 vs. male EL 2.4–2.6 mm, 2.5 ± 0.1 mm, N = 5; female EL 2.5–2.7 mm, 2.6 ± 0.1 mm, N = 2; absence of maxillary and vomerine teeth; finger and toe tips rounded, with small discs; presence of well-developed subarticular tubercles on all fingers and toes, rounded, alternating with additional smaller tubercles; prominent inner metatarsal tubercle and a small outer metatarsal tubercle on foot; webbing between fingers absent; rudimentary webbing between toes; lateral surfaces from tip of the snout up to the groin prominently dark blackish-brown; two prominent dark blackish-brown ‘false-eye’ like spots on either side of the groin extending just above the hind legs; a thin mid-dorsal line invariably extending from tip of the snout up to the vent; ventral surfaces of throat, belly, arms and legs dark brown with a violet tinge and various sized greyish-white blotches and speckles. This new genus can also be distinguished from other members of the subfamily by its hand musculature in having the m. flexor teres digiti III ventral to both slips of the m. transversus metacarpus 138; and the dorsal surface with two previously unreported flexor muscles on digits III and IV, one lateral to the m. lumbricalis brevis digiti III, and the other medial to the medial slip of the m. lumbricalis brevis digiti IV (Fig. 1).

Scale bars = 0.5 mm.

    

Mysticellus franki sp. nov

Etymology: The species name, franki, is a Latin genitive honoring evolutionary biologist Prof Franky Bossuyt (Vrije Universiteit Brussel), recognizing his role in global amphibian research and education, and particularly for his contribution to the study of Indian amphibians.

Suggested common name: Franky’s Narrow-mouthed Frog.

Ecology and Behavior: A large number of animals usually aggregate around temporary water collection sites about two to three days after the first monsoon showers. Individuals were collected from grass adjacent to water puddles in a small wayside quarry (about 25 m2 area). The specific site was located close to a secondary forest. Breeding activities were observed only for four to five days, after which the animals disappeared and no individuals could be located despite repeated visits. Tadpoles (stage 34) were observed at the same site towards the end of July (Fig. 1g–i). Calling males exhibited a peculiar behavior of raising the hind part of their body displaying a pair of black ‘false-eye’ like spots. On some occasions, similar behavior was observed when individuals were disturbed, suggesting that the ‘false-eye’ spots may be serving a defensive role against predators (Fig. 1c).

Distribution: Mysticellus franki gen. et. sp. nov. is presently known only from the type locality in southern Western Ghats region of Kerala, Peninsular India (Fig. 2).

ABSTRACT 
Microhyla ornata, a species originally described from the southwest coast of India in 1841, was long reported to be wide-ranging throughout South, Southeast, and East Asia. Although the name M. ornata is restricted to populations from South Asia, the species is still considered to occur widely in India and its neighboring regions. To clarify the identity and geographical distribution of M. ‘ornata’, we performed DNA barcoding using a fragment of the mitochondrial 16S rRNA gene from 62 newly obtained samples. Our results show that this taxon is restricted to Peninsular India and Sri Lanka, whereas, populations from the other parts represent three different species – M. mukhlesuri, M. mymensinghensis, and M. nilphamariensis, creating new country records for India. Our work reemphasizes the benefits of DNA barcoding for rapidly identifying populations of widespread species and provides insights into the patterns of genetic differentiation in the M. ‘ornata’ species complex of South Asia. 

KEYWORDS: 16S; cryptic species; DNA barcoding; haplotype network; species distribution

Figure 1. DNA barcoding based on mitochondrial 16S rRNA gene sequences ( 540 bp). (A) Maximum Likelihood RAxML tree from total 145 newly sampled and previously available populations of Microhyla mukhlesuri, M. mymensinghensis, M. nilphamariensis, and M. ornata, along with sequences representing 24 other Microhyla species. Kaloula pulchra was used as the outgroup taxon. Bayesian Posterior Probabilities and RAxML bootstrap values >50% are indicated above and below the branches, respectively. Closed circles indicate samples from the present study; open circles indicate GenBank sequences. Geographical distribution of species is shown on the right panel. (B) Frequency distribution of intra- and interspecific sequence divergences for Microhyla mukhlesuri, M. mymensinghensis, M. nilphamariensis, and M. ornata, based on uncorrected and K2P pairwise distances.

Figure 2. Median-Joining haplotype network based on 147 mitochondrial 16S rRNA gene sequences from six closely related Microhyla species. Circle sizes are proportional to the number of haplotype sequences involved, as represented with numbers inside the circles. Black circles represent median vectors. Each branch represents one mutation step; black bars represent additional mutation steps. A schematic representation of species relationships with respect to geographical distribution is shown over the map.
