Abstract

A new species of the genus Megophrys is described from Guizhou Province, China. Molecular phylogenetic analyses based on mitochondrial DNA indicated the new species as a clade clustered into the Megophrys clade. The new species can be distinguished from its congeners by a combination of the following characters: body size moderate (SVL 40.0–45.5 mm in males and 48.9–51.2 mm in females); vomerine teeth absent; tongue not notched behind; tympanum distinctly visible, oval; a small horn-like tubercle at the edge of each upper eyelid; two metacarpal tubercles in hand; toes with rudimentary webbing; heels overlapping when thighs are positioned at right angles to the body; tibiotarsal articulation reaching the level of mid-eye when leg stretched forward; in breeding males, an internal single subgular vocal sac present and brownish nuptial pads, made up of black nuptial spines, present on the dorsal base of the first two fingers.

Keywords: Molecular phylogenetic analysis, morphology, new species, taxonomy

Introduction

The Asian horned toad Megophrys Kuhl & Van Hasselt, 1822 (Anura: Megophryidae Bonaparte, 1850) is widely distributed in eastern and central China, throughout southeastern Asia, and extending to the islands of the Sunda Shelf and the Philippines (Frost 2020). This group was indicated to be a monophyletic group by most molecular phylogenetic studies (e.g., Chen et al. 2017; Mahony et al. 2017; Liu et al. 2018; Li et al. 2018a; Liu et al. 2020; Wang et al. 2020) though the taxonomic profiles especially on generic assignments of species in the group are still on debate (e.g., Tian and Hu 1983; Dubois 1987; Rao and Yang 1997; Lathrop 1997; Jiang et al. 2003; Delorme et al. 2006; Fei et al. 2009; Fei and Ye 2016; Chen et al. 2017; Deuti et al. 2017; Mahony et al. 2017; Liu et al. 2018; Frost 2020). Currently, the genus Megophrys contains 106 species, of which, 49 species were described in the last ten years (Frost 2020). Molecular phylogenetic frameworks even still proposed many cryptic species in the genus (e.g., Chen et al. 2017; Liu et al. 2018). In Guizhou Province, China, in recent five years, four Megophrys species have been described, and they are, M. liboensis Zhang, Li, Xiao, Li, Pan, Wang, Zhang & Zhou, 2017, M. leishanensis Li, Xu, Liu, Jiang, Wei & Wang, 2018, M. jiangi Liu, Li, Wei, Xu, Cheng, Wang & Wu, 2020, and M. chishuiensis Xu, Li, Liu, Wei & Wang, 2020.

During field surveys in Anlong County, Guizhou Province, China, we collected eight Megophrys specimens. Molecular phylogenetic analyses and morphological comparisons supported it as an undescribed species and it is described herein as a new species.

Materials and methods

Sampling

Three adult females and five adult males of the undescribed species were collected from Anlong County, Guizhou Province, China (Fig. 1; Table 1). The toads were firstly euthanised using isoflurane, and then the specimens were fixed in 75% ethanol for preservation. Tissue samples were taken and preserved separately in 95% ethanol prior to fixation. The specimens were deposited in Chengdu Institute of Biology, Chinese Academy of Sciences (CIB, CAS).

Phylogenetic analyses

Six specimens of the undescribed species were included in the molecular analyses (Table 2). Total DNA was extracted using a standard phenol-chloroform extraction protocol (Sambrook et al. 1989). Two fragments of the mitochondrial 16S rRNA (16S) and cytochromeoxidase subunit I (COI) genes were amplified. For 16S gene, the primers P7 (5’-CGCCTGTTTACCAAAAACAT-3’) and P8 (5’-CCGGTCTGAACTCAGATCACGT-3’) were used following Simon et al. (1994), and for COI gene, Chmf4 (5’-TYTCWACWAAYCAYAAAGAYATCGG-3’) and Chmr4 (5’-ACYTCRGGRTGRCCRAARAATCA-3’) were used following Che et al. (2012). The fragments were amplified under the following conditions: an initial denaturing step at 95 °C for 4 min; 36 cycles of denaturing at 95 °C for 30 s, annealing at 52 °C (for 16S)/47 °C (for COI) for 40 s and extending at 72 °C for 70 s. Sequencing was conducted using an ABI3730 automated DNA sequencer in Shanghai DNA BioTechnologies Co., Ltd. New sequences were deposited in GenBank (for GenBank accession numbers see Table 2).

For molecular analyses, the available sequence data for congeners of Megophrys were downloaded from GenBank (Table 2), primarily from previous studies (Chen et al. 2017; Liu et al. 2018). For phylogenetic analyses, corresponding sequences of one Leptobrachella oshanensis (Liu, 1950) and one Leptobrachium boringii (Liu, 1945) were also downloaded from GenBank (Table 2), and used as outgroups according to Mahony et al. (2017). Sequences were assembled and aligned using the Clustalw module in BioEdit v.7.0.9.0 (Hall 1999) with default settings. Alignments were checked by eye and revised manually if necessary. For phylogenetic analyses of mitochondrial DNA, the dataset concatenated with 16S and COI gene sequences. To avoid under- or over-parameterisation (Lemmon and Moriarty 2004; McGuire et al. 2007), the best partition scheme and the best evolutionary model for each partition were chosen for the phylogenetic analyses using PARTITIONFINDER v. 1.1.1 (Robert et al. 2012). In this analysis, 16S gene and each codon position of COI gene were defined, and Bayesian Inference Criteria was used. As a result, the analysis suggested that the best partition scheme is16S gene/each codon position of COI gene, and selected GTR + G + I model as the best model for each partition. Phylogenetic analyses were conducted using maximum likelihood (ML) and Bayesian Inference (BI) methods, implemented in PhyML v. 3.0 (Guindon et al. 2010) and MrBayes v. 3.12 (Ronquist and Huelsenbeck 2003), respectively. For the ML tree, branch supports were drawn from 10,000 nonparametric bootstrap replicates. In BI, two runs each with four Markov chains were simultaneously run for 50 million generations with sampling every 1,000 generations. The first 25% trees were removed as the “burn-in” stage followed by calculations of Bayesian posterior probabilities and the 50% majority-rule consensus of the post burn-in trees sampled at stationarity. Finally, genetic distance between species based on uncorrected p-distance model was estimated on each gene using MEGA v. 6.06 (Tamura et al. 2013).

Morphological comparisons

All eight adult specimens of the undescribed species were measured (Table 1). The terminology and methods followed Fei et al. (2009). Measurements were taken with a dial caliper to 0.1 mm. Seventeen morphometric characters of adult specimens were measured:

ED eye diameter (distance from the anterior corner to the posterior corner of the eye);

FL foot length (distance from tarsus to the tip of fourth toe);

HDL head length (distance from the tip of the snout to the articulation of jaw);

HDW maximum head width (greatest width between the left and right articulations of jaw);

HLL hindlimb length (maximum length from the vent to the distal tip of the Toe IV);

IND internasal distance (minimum distance between the inner margins of the external nares);

IOD interorbital distance (minimum distance between the inner edges of the upper eyelids);

LAL length of lower arm and hand (distance from the elbow to the distal end of the Finger IV);

LW lower arm width (maximum width of the lower arm);

SVL snout-vent length (distance from the tip of the snout to the posterior edge of the vent);

SL snout length (distance from the tip of the snout to the anterior corner of the eye);

TFL length of foot and tarsus (distance from the tibiotarsal articulation to the distal end of the Toe IV);

THL thigh length (distance from vent to knee);

TL tibia length (distance from knee to tarsus);

TW maximal tibia width;

TYD maximal tympanum diameter;

UEW upper eyelid width (greatest width of the upper eyelid margins measured perpendicular to the anterior-posterior axis).

The undescribed species was also compared with all other congeners on morphology. Comparative data were obtained from related species as described in literature (Table 3).

Bioacoustics data

The advertisement calls of the undescribed species were recorded from the holotype specimen CIBAL20190531018 in the field on 31 May 2019 in Anlong County, Guizhou Province, China. The advertisement call of the undescribed species was recorded in the stream at ambient air temperature of 18.5 °C and air humidity of 83%. SONY PCM-D50 digital sound recorder was used to record within 30 cm of the calling individual. The sound files in wave format were resampled at 48 kHz with sampling depth 24 bits. The sonograms and waveforms were generated by WaveSurfer software (Sjöander and Beskow 2000) from which all parameters and characters were measured. Ambient temperature was taken by a digital hygrothermograph.

Results

Phylogenetic analyses

Aligned sequence matrix of 16S+COI contains 1104 bp. ML and BI trees of the mitochondrial DNA dataset presented almost consistent topology (Fig. 2). In mitochondrial DNA trees, all samples of the undescribed species were clustered into one clade which was nested into the Megophrys clade. However, the relationships between the undescribed species and its related species were not resolved though it was likely sister to M. binchuanensis in topology.

Maximum likelihood (ML) tree of the genus Megophrys reconstructed based on the 16S rRNA and COI gene sequences. Bayesian posterior probability/ML bootstrap supports were denoted beside each node. Samples 1–90 refer to Table 2.

Genetic distances between samples of the undescribed species either on 16S or on COI genes were below 0.2% much lower than the interspecific genetic distance between recognised Megophrys species (Suppl. materials 1, 2). The genetic distance between the undescribed species and its closest related species M. binchuanensis were 2.3% and 10.0% on 16S and COI, respectively, which was higher than or at the same level with those among many pairs of sister species, such as, 2.1% and 6.3% on 16S and COI respectively between M. wushanensis and M. baolongensis, 1.7% and 3.8% on 16S and COI respectively between M. spinata and M. sangzhiensis (Suppl. materials 1, 2).

Morphological comparisons

The new species could be identified from its congeners in a series of morphological characters (Suppl. material 3). The detailed demonstration based on morphological comparisons see the following section on describing the new species.

Distribution and habitats.

Megophrys anlongensis sp. nov. is known only from the type locality, Anlong County, Guizhou Province, China at elevations between 1400–1600 m. The individuals were frequently found near the streams surrounded by evergreen broadleaved forests (Fig. 7).

Etymology.

The specific name anlongensis refers to the known distribution of this species, Anlong County, Guizhou Province, China. We propose the common English name “Anlong horned toad”, and Chinese name “An Long Jiao Chan” (安龙角蟾).

Discussion

Southwestern China was proposed as biodiversity hotspot (Myers et al. 2000). Guizhou Province, China is an important part of southwestern China, especially concerning the particular environments of karst rocky desertification, and knowledge of biodiversity levels and/or patterns are still seriously lacking in this region. Recently, a series of new amphibian species were described from Guizhou Province (Zhang et al. 2017; Li et al. 2018a, b, 2019a, b; Lyu et al. 2019; Wang et al. 2019c; Luo et al 2020; Liu et al 2020; Wei et al, 2020; Xu et al, 2020, Li et al, 2020), highlighting the underestimation of the species diversity of this province. For the genus Megophrys, molecular phylogenetic differences still suggested some cryptic species in or near this region (Liu et al. 2018), but Megophrys anlongensis sp. nov. was not found before. This indicates that more work should focus on detailed information for describing such species, and additionally, comprehensive and in-depth surveys should be led to discover more cryptic species of the genus in this province. According to our surveys, habitat degradation due to construction and human activities are impacting the population of Megophrys anlongensis sp. nov. Hence, it is urgent for us to understand its population status and suggest strategies for supplying conservation needs of the species.
