Integrative taxonomy of Leptonetela spiders (Araneae, Leptonetidae), with descriptions of 46 new species

Abstract

Extreme environments, such as subterranean habitats, are suspected to be responsible for morphologically inseparable cryptic or sibling species and can bias biodiversity assessment. A DNA barcode is a short, standardized DNA sequence used for taxonomic purposes and has the potential to lessen the challenges presented by a biotic inventory. Here, we investigate the diversity of the genus Leptonetela Kratochvíl, 1978 that is endemic to karst systems in Eurasia using DNA barcoding. We analyzed 624 specimens using one mitochondrial gene fragment (COI). The results show that DNA barcoding is an efficient and rapid species identification method in this genus. DNA barcoding gap and automatic barcode gap discovery (ABGD) analyses indicated the existence of 90 species, a result consistent with previous taxonomic hypotheses, and supported the existence of extreme male pedipalpal tibial spine and median apophysis polymorphism in Leptonetela species, with direct implications for the taxonomy of the group and its diversity. Based on the molecular and morphological evidence, we delimit and diagnose 90 Leptonetela species, including the type species Leptonetela kanellisi(Deeleman-Reinhold, 1971). Forty-six of them are previously undescribed. The female of Leptonetela zhai Wang & Li, 2011 is reported for the first time. Leptonetela tianxinensis (Tong & Li, 2008) comb. nov. is transferred from the genus Leptoneta Simon, 1872;the genus Guineta Lin & Li, 2010 syn. nov. is a junior synonym of Leptonetela; Leptonetela gigachela(Lin & Li, 2010) comb. nov. is transferred from Guineta. The genus Sinoneta Lin & Li, 2010 syn. nov. is a junior synonym of Leptonetela; Leptonetela notabilis(Lin & Li, 2010) comb. nov. and Leptonetela sexdigiti(Lin & Li, 2010) comb. nov. are transferred from Sinoneta; Leptonetela sanchahe Wang & Li nom. nov. is proposed as a replacement name for Sinoneta palmata(Chen et al, 2010) because Leptonetela palmata is preoccupied.

INTRODUCTION

Subterranean ecosystems, such as caves and cracks, are evident mainly in karst areas, which represent nearly 4% of the rocky outcrops of the world. These environments are marked by permanent darkness, a lack of diurnal and annual rhythms, and extremely scarce food sources (Culver & White, 2005; Howarth, 1983; Poulson & White, 1969). Many studies show that despite stressful and unfavorable conditions, the subsurface habitat harbors diverse animal communities (mainly invertebrates) (Amara-Zettler et al, 2002; Flot et al, 2010; López-García et al, 2001; Mathieu et al, 1997; Niemiller et al, 2012; Sket, 1999). Troglobionts are expected to adopt strategies that are characterized by significant geographic isolation and numerous local endemics (Convey, 1997; Waterman, 2001). Because the diversity of possible adaptive responses declines with stress intensity (Nevo, 2001), evolution in harsh environments is also expected to be influenced by convergence (Little & Vrijenhoek, 2003; Rothschild & Mancinelli, 2001; Waterman, 2001). Therefore, in subterranean, and more generally in extreme environments, diversification and speciation processes should be largely influenced by island-like habitats, such as caves, allopatric speciation and vicariant events, and could be masked by morphological convergence. For these groups of organisms, morphology alone cannot determine species boundaries, so identifying morphologically inseparable cryptic or sibling species requires an integrative approach that often includes DNA analysis.

DNA barcoding relies on the use of a standardized DNA region as a tag for accurate and rapid species identification (Hebert & Gregory, 2005) and has been used to help overcome the 'taxonomic impediment' (Herbert et al, 2003a; Tautz et al, 2003). It aids in the identification of species in applied settings, the association of morphologically distinct life-cycle forms within a species, the detection of host-specific lineages and the detection of morphologically cryptic species (Miller & Foottit, 2009). DNA barcoding has been used in a diverse range of vertebrate and invertebrate taxa (Clare et al, 2007; Ratnasingham & Hebert, 2007) and has enabled an increasing number of taxa to be identified. For example, a survey of crustacean stygofauna suggests that there could be substantial levels of subterranean biodiversity hidden in Australia's acquifer (Asmyhr & Cooper, 2012). Nevertheless, the exclusive use of single-locus molecular gene fragments is not without risks, for identical mitochondrial DNA sequences can be present in unrelated species due to introgression, or incomplete lineage sorting (Ballard & Whitlock, 2004). Additionally, the use of a divergence threshold for distinguishing intra-vs. interspecific sequence variation (Hebert et al, 2003a) can seriously compromise species identification and suffers from severe statistical problems (Vences et al, 2005). Furthermore, species misidentification has been observed when a reference database is not comprehensive; such that is does not contain all the species of the group under study (Meyer & Paulay, 2005).

The South China karst, a United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Site since 2007, is noted for its karst features and landscapes as well as rich biodiversity. Numerous subterraean species have been reported in this region, especially invertebrate fauna (Zhang, 1986). The spider genus Leptonetela is discontinuously distributed in the South China karst and the Balkan Peninsula, a karstic region in Europe. The genus has 54 catalogued species (World Spider Catalog, 2017), and with one exception (L. pungitia Wang & Li, 2011), nearly all Leptonetela species are endemic to either a single cave or a cave system. The spiders are cave adapted as shown by morphological features, such as vestigial eyes and highly reduced skin pigmentation. Over the past nine years, we have conducted extensive surveys of subterranean biodiversity in Eurasia. More than 1 500 caves were visited, and we ultimately sampled 122 Leptonetela populations (caves). Rapid and accurate identification within this genus is difficult due to congeneric species sharing similar morphological traits, a lack of obvious morphological differences between closely related species and some species only differ in one or a few quantitative differences, such as the location, length ratio or thickness of the male pedipalpal tibial spines and the number of teeth on the median apophysis.

In this study, we test the usefulness of DNA barcoding for species identification in the subterranean genus Leptonetela and investigate the diversity of the genus. The standard molecular barcode, cytochrome c oxidase subunit Ⅰ (COI) was used. A species discovery method, automatic barcode gap discovery (ABGD) (Puillandre et al, 2012), and a species validation method, DNA barcoding gap analysis, (Hebert et al, 2003b) were both used, depending on whether the samples were partitioned prior to analysis. The main goals of our study were: (ⅰ) to test whether the COI barcoding fragment can reliably resolve and identify subterranean Leptonetela species by comparing the COI barcode fragment results with those from morphological data; (ⅱ) to test taxonomic value of morphological characters used in traditional methods of classification.

MATERIALS AND METHODS

Taxon sampling

We sampled 624 Leptonetela individuals from 122 populations (caves) (Supplementary Table S1) in Eurasia (Insular and Peninsular Greece, and Southeast Asia; see inset in Figure 1). Nine individuals from three other genera of the family Leptonetidae were chosen as outgroups. All specimens were collected alive, fixed in absolute ethanol, and the legs were removed for subsequent DNA extraction. The remaining specimens were preserved in 80% ethanol for identification and morphological examination. Voucher specimens and all type specimens were deposited in the Institute of Zoology, Chinese Academy of Sciences (IZCAS), Beijing, China.

Molecular protocols

Total genomic DNA was extracted using the Animal Genomic DNA Isolation Kit (Dingguo, Beijing, China) following the manufacturer's protocol. We amplified the cytochrome c oxidase subunit Ⅰ (COI) barcode region using the primer pairs LCOI490/HCO2198 (Folmer et al, 1994). PCR reaction conditions were: initial denaturation at 94 ℃ for 1 min; 35 cycles of denaturation at 94 ℃ for 1 min, annealing at 45 ℃ for 45 s, and elongation at 70 ℃ for 60 s; and a final extension at 72 ℃ for 5 min. The 25 μL PCR reactions included 17.25 μL of double-distilled H₂O, 2.5 μL of 10× Taq buffer (mixed with MgCl₂; TianGen Biotech, Beijing, China), 2.0 μL of dNTP Mix (2.5 mmol/L), 1 μL of each forward and reverse 10 μmol/L primer, 1 μL of DNA template, and 0.25 μL Taq DNA polymerase (2.5 U/μL; TianGen Biotech, Beijing, China). Double-stranded PCR products were visualized by agarose gel electrophoresis (1% agarose). PCR products were purified and sequenced by Sunny Biotechnology Co., Ltd (Shanghai, China) using the ABI 3730XL DNA analyser. Sequences were aligned using ClustalW in Mega 6.0 (Tamura et al, 2013), with visual inspection, translation, and manual adjustment to minimize alignment error. The most appropriate phylogenetic model for the sequence alignment was selected using jModelTest2 (Darriba et al, 2012) under the Akaike Information Criterion (Posada & Crandall, 1998).

Phylogenetic analyses

Phylogenetic analyses were performed using maximum likelihood (ML) in RAXML v. 7.0.3 with the GTRCAT model (Stamatakis, 2006). One hundred replicate ML inferences were performed in the search for an optimal ML tree, each initiated with a random starting tree and employing the default rapid hill-climbing algorithm. Clade confidence was assessed with a rapid bootstrap of 1 000 replicates.

Species delineation

We analyzed the COI barcode dataset (see Supplementary Table S1) using two species delineation methods. DNA barcoding gap analyses require an a priori species designation. Therefore, we divided the 624 Leptonetela individuals of 122 populations (caves) into 90 putative species based on morphological characters and geographic information. In our DNA barcoding gap analysis, we examined the overlap between the mean intraspecific and interspecific Kimura 2-parameter (K2P) (Kimura, 1980) and uncorrected p-distance (Nei & Kumar, 2000) for each candidate species, as calculated by Mega v. 6.0 (Tamura et al, 2013).

The automatic barcode gap discovery procedure (ABGD) (<xref ref-type="bibr" rid="b31-ZoolRes-38-6-321">Puillandre et al, 2012</xref>), which does not require assigning samples to putative species, calculates all pairwise distances in the dataset, evaluates intraspecific divergences, and then sorts the samples into candidate species using the calculated distances. We performed ABGD analyses online (<a href="http://wwwabi.snv.jussieu.fr/public/abgd/" target="_blank">http://wwwabi.snv.jussieu.fr/public/abgd/</a>), using three different distance metrics: Jukes-Cantor (JC69) (<xref ref-type="bibr" rid="b18-ZoolRes-38-6-321">Jukes & Cantor, 1969</xref>), Kimura 2-parameter (K2P) (<xref ref-type="bibr" rid="b19-ZoolRes-38-6-321">Kimura, 1980</xref>), and simple distance (<italic>p</italic>-distance) (<xref ref-type="bibr" rid="b26-ZoolRes-38-6-321">Nei & Kumar, 2000</xref>). We analyzed the data using two different values for the parameters Pmin (0.0001 and 0.001), Pmax (0.1 and 0.2), and relative gap width (X=1 or 1.5), with all other parameters at default values.

RESULTS

In total, 624 DNA barcodes were analyzed. A full list of the analyzed specimens can be found in Supplementary Table S1. Fragment lengths of the analyzed DNA barcodes ranged from 107 (0.005%) to 617 bp (89%). For all populations, except L. kanellisi and L. robustispina, four or more DNA barcodes were generated. All nucleotides were translated into functional protein sequences in the correct reading frame, with no stop codons or indels observed. Similar to other arthropod studies, our data indicated a high AT-content for this mitochondrial gene fragment: the mean sequence compositions were A=20.5%, C=12.6%, G=24.4%, T=41.4%.

Phylogenetic inference

The ML gene tree topology suggests that Leptonetela is monophyletic, with the node highly supported (Figure 2; bootstrap value, BS=92). Our analyses revealed all Leptonetela species formed non-overlapping clusters, with bootstrap support values of 100. In contrast, relationships among putative species were largely unresolved, usually with low bootstrap support on the ML gene tree, particularly at deeper phylogenetic levels.

Species delineation

DNA barcoding gap analysis: Based on our a priori species hypotheses, Interaspecific divergences ranged from zero to 5.3/5.0% (K2P/uncorrected p-distance) whereas interspecific distances were between 3.1/3% and 31.9/25% (K2P/uncorrected p-distance). Maximum intraspecific distances > 3% were found for two species, including L. reticulopecta (4.3/4.0%), and L. pentakis Lin & Li, 2010 (5.3/5%). The lowest interspecific distance were revealed for the two species pairs L.changtu Wang & Li sp. nov. with L. chuan Wang & Li sp. nov. and L. kangsa Wang & Li sp. nov. with L. shibingensis Guo, Yu & Chen, 2016 with a value of 3.1/3%. Minimum interspecific pairwise distances < 5%, and > 3% were found for two species pairs: L. shibingensis with L. shanji Wang & Li sp. nov. and L. dao Wang & Li sp. nov. with L. xiaoyan Wang & Li sp. nov. The mean interspecific distance between the 90 tentative species was 17.9/15.6% (K2P/uncorrected p-distance), and the mean intraspecific distance within each species was 0.2% (both K2P and uncorrected p-distance) in Leptonetela. A histogram of the gap and overlap between intra-and interspecies genetic distances are show in Figure 3.

ABGD analysis

The ABGD analyses of the COI dataset, using the originally specified parameter combinations and partitions resulted mostly in 90 distinct species that correspond to the 90 species observed in the previous taxonomic hypotheses based on morphology. The result was the same regardless of the model of evolution employed (Jukes-Cantor (JC), K2P, Simple Distance). The settings P min/P max=0.0001/0.2 yielded the most significant P values. However, at lower values of prior intraspecific distance (P), recursive partitioning of ABGD recognized more species (Table 1) when P min/P max=0.0001/0.2, P values=0.159, JC and K2P distance resulted in 98 species, and simple distance resulted in 95 species.

DISCUSSION

DNA barcoding is widely recognized as a useful tool for species identification across the animal kingdom (Chesters et al, 2012; Wang et al, 2011). Our research represents an important step towards the application of DNA barcodes for identification of Leptonetela taxa, and for 119 taxa (97%), our data represent the first published DNA barcodes.

Classically, geographic isolation is considered a primary feature of troglobitic taxa (Hedin, 1997; Hedin & Thomas, 2010). Our DNA barcoding result is consistent with this view and similar to other DNA barcoding studies, in which COI showed high genetic structure between populations within species (Tavares et al, 2001).

Choosing appropriate thresholds that can delimit species is one of the main challenges and concerns for DNA barcoding research (Ferguson, 2002). Our DNA barcoding gap analysis shows an overlap in the range of intra-and interspecific COI sequence divergence. The interspecific genetic divergences between L. chuan Wang & Li sp. nov. and L. changtu Wang & Li sp. nov., L. kangsa Wang & Li sp. nov. and L. shibingensis, as well as between L. shibingensis and L. shanji Wang & Li sp. nov. was 3.1/3.0% based on K2P/uncorrected and p-distance models. Compared with other species L. chuan Wang & Li sp. nov., and L. changtu Wang & Li sp. nov., L. kangsa Wang & Li sp. nov., L. shibingensis and L. shanji Wang & Li sp. nov. are more closely distributed. In morphology, L. chuan Wang & Li sp. nov. and L. changtu Wang & Li sp. nov. can be distinguished by the shape of the median apophysis and the conductor (median apophysis palm-shaped, edge with sclerotized spots, conductor semicircular in L. changtu Wang & Li sp. nov., median apophysis rectangular, with 5 larger teeth distally, conductor triangular in ventral view in L. chuan Wang & Li sp. nov.); L. kangsa Wang & Li sp. nov., L. shibingensis and L. shanji Wang & Li sp. nov. can be distinguished by the location and pattern of male pedipalpal tibial spines (Ⅰ spine located at the middle in L. shibingensis and L. shanji Wang & Li sp. nov.; Ⅰ spine asymmetrically bifurcated in L. shanji Wang & Li sp. nov., male pedipalpal tibia Ⅰ spine located at base and not bifurcated in L. kangsa Wang & Li sp. nov.). Nevertheless, we found two species with maximum pairwise distance > 3%, including L. reticulopecta (specimens from Tianshegnqiao Cave are clearly distant from the rest) with 4.3/4.0%, L. pentakis (specimens from Liaoya cave is clearly distant from the rest) with 5.3/5.0%. Then we achieved a threshold of 3.11/3.0% (K2P/uncorrected and p-distance), excluding taxa from Tianshegnqiao Cave and Liaoya Cave. This threshold was interestingly close to the 3% commonly used in barcoding literature (Hebert et al, 2003a, b).

Here, we were highly successful using ABGD for identification. In ABGD analysis, the taxa from Tianshegnqiao Cave and Liaoya Cave were identified as L. reticulopecta and L. pentakis, respectivelly. Given that all specimens of L. reticulopecta and L. pentakis are morphologically very similar, we are currently unable to ascertain if the observed genetic distances simply represent a high level of intraspecific variation or reflect cryptic species between the taxa of L. reticulopecta and L. pentakis. To answer this question, more specimens need to be collected and analyzed, using both morphological characters and nuclear sequence data.

In conclusion, our study demonstrates the power of an integrative approach, in which both classical and DNA barcoding taxonomy complements each other and both contribute to a more accurate taxonomic classification.

Etymology. The specific name refers to the type locality; noun.

Remarks. Qianleptoneta palmata was collected from Sanchahe Cave in Guizhou, China and published by Chen et al. in December 2010. Wang & Li (2011) transfered Qianleptoneta palmata Chen et al, 2010 to the genus Sinoneta Lin & Li, 2010. Nevertheless, in this study our results confirmed that Qianleptoneta palmata belonged to the genus Leptonetela.

Leptonetela palmata is a preoccupied name (secondary homonym) for a species collected from Dixian Cave in Guizhou, China and published by Lin & Li, in August 2010. Subsequently, Leptonetela sanchahe Wang & Li nom. nov. is proposed for the taxon from Sanchahe Cave, in Guizhou, China.
