RESUMO
BACKGROUND: DNA barcoding has been developed as a useful tool for species discrimination. Several sequence-based species delimitation methods, such as Barcode Index Number (BIN), REfined Single Linkage (RESL), Automatic Barcode Gap Discovery (ABGD), a Java program uses an explicit, determinate algorithm to define Molecular Operational Taxonomic Unit (jMOTU), Generalized Mixed Yule Coalescent (GMYC), and Bayesian implementation of the Poisson Tree Processes model (bPTP), were used. Our aim was to estimate Chinese katydid biodiversity using standard DNA barcode cytochrome c oxidase subunit I (COI-5P) sequences. RESULTS: Detection of a barcoding gap by similarity-based analyses and clustering-base analyses indicated that 131 identified morphological species (morphospecies) were assigned to 196 BINs and were divided into four categories: (i) MATCH (83/131 = 64.89%), morphospecies were a perfect match between morphospecies and BINs (including 61 concordant BINs and 22 singleton BINs); (ii) MERGE (14/131 = 10.69%), morphospecies shared its unique BIN with other species; (iii) SPLIT (33/131 = 25.19%, when 22 singleton species were excluded, it rose to 33/109 = 30.28%), morphospecies were placed in more than one BIN; (iv) MIXTURE (4/131 = 5.34%), morphospecies showed a more complex partition involving both a merge and a split. Neighbor-joining (NJ) analyses showed that nearly all BINs and most morphospecies formed monophyletic cluster with little variation. The molecular operational taxonomic units (MOTUs) were defined considering only the more inclusive clades found by at least four of seven species delimitation methods. Our results robustly supported 61 of 109 (55.96%) morphospecies represented by more than one specimen, 159 of 213 (74.65%) concordant BINs, and 3 of 8 (37.5%) discordant BINs. CONCLUSIONS: Molecular species delimitation analyses generated a larger number of MOTUs compared with morphospecies. If these MOTU splits are proven to be true, Chinese katydids probably contain a seemingly large proportion of cryptic/undescribed taxa. Future amplification of additional molecular markers, particularly from the nuclear DNA, may be especially useful for specimens that were identified here as problematic taxa.

Although mitogenomes are useful tools for inferring evolutionary history, only a few representative ones can be used for most Ensifera lineages. Thirty-two ensiferan mitogenomes were determined using ABI Sanger sequencing and standard primer walking of 2-3 overlapping Long-PCR fragments, or Illumina® HiSeq2000 for "shotgun" sequenced long-PCR-amplified mitochondrial or total genomic DNA. Six patterns of gene arrangements, including the novel trnR-trnSAGN-trnA-trnN-trnG-nad3 in Lipotactes tripyrga (Lipotactinae), were identified from 59 ensiferan mitogenomes. The results suggest that trnM-trnI-trnQ and trnA-trnR-trnE-trnSAGN-trnN-trnF rearrangements might be a shared derived character in Pseudophyllinae and Gryllidae, respectively. We found base composition biases in our dataset, which potentially complicate the inference of higher-level ensiferan phylogeny. Site-heterogeneous Bayesian inference (BI) and site-homogeneous maximum likelihood (ML) analyses recovered all ensiferan superfamilies as monophyletic. The site-homogeneous BI analysis failed to recover the monophyly of Stenopelmatoidea. As Schizodactyloidea was only represented by Comicus campestris, its monophyly could not be tested. In the Triassic/Jurassic boundary, Ensifera diverged into grylloid and non-grylloid clades. All analyses confirmed Grylloidea and Gryllotalpoidea as sister groups. Site-heterogeneous BI analysis found Schizodactyloidea as the most basal lineage and sister to the clade formed by Grylloidea and Gryllotalpoidea, but the site-homogeneous analyses placed it basally to the non-grylloid clade and recovered a sister relationship between Tettigonioidea and (Hagloidea, Rhaphidophoroidea, Stenopelmatoidea), although this clade had a low support. The site-heterogeneous BI analysis found Tettigonioidea and Hagloidea were sister groups (posterior probability (PP)=0.99), Stenopelmatoidea was sister to (Tettigonioidea, Hagloidea) (PP>0.91), and Rhaphidophoroidea was basal to the non-grylloid clade. At a lower level, all analyses divided Tettigonioidea into Phaneropteridae and Tettigoniidae.
