Sequence-based species delineation and molecular phylogenetics of the transitional Nearctic–Neotropical grasshopper genusTaeniopoda(Orthoptera, Romaleidae)

Phylogeny and species delimitation of the genus Longgenacris and Fruhstorferiola viridifemorata species group (Orthoptera: Acrididae: Melanoplinae) based on molecular evidence

“…As for the four MOUTs delineated by GMYC analysis using COI gene ( S10 Table ), they didn't be supported by either morphological or geographical informations. Furthermore, this approach tends to overestimate the number of species because of errors in reconstruction of ultrametric input trees [ 49 , 50 ], or in the presence of high population structure or considerably high values of effective population size [ 51 , 52 ], especially when mitochondrial genomic dataset is employed [ 11 ]. Although GMYC was considered a robust tool for delimiting species when only single-locus information was available [ 53 ], it cannot be used as sufficient evidence for evaluating the specific status of particular cases without additional data [ 54 ].…”

“…Species delimitation using molecular data has attracted more and more attention from systematists and taxonomists because of the rapid development of sequencing techniques and bioinformatic methods. There are many successful cases in grasshoppers using molecular evidence for species delimitation so far [ 5 , 6 , 8 , 9 , 11 – 14 , 19 – 21 ]. Molecular approaches for species delimitation can be used not only to confirm delimitations proposed by traditional taxonomy [ 11 ], but also to delimit new species under an integrative taxonomy framework despite the possibility of oversplitting sometimes [ 9 ].…”

As for the molecular markers, the most frequently employed one is the mitochondrial gene COI , which was used either alone [ 9 , 14 ] or together with some other markers [ 5 , 8 , 11 , 20 ].…”

Molecular systematics of the Dichopetala genus group (Orthoptera: Phaneropteridae)

“…However, as in other orthopteran taxa (e.g. De Jesús-Bonilla, Barrientos-Lozano, & Zaldívar-Riverón, 2017;Sanabria-Urbán, Song, Oyama, González-Rodríguez, & Cueva Del Castillo, 2017), species delimitation and recognition of supraspecific groups in this subfamily have been considerably problematic. The latter due to the existence of species complexes in an apparent initial state of differentiation, and the recent discovery of several new species and genera for the subfamily (Arce-Pérez & Morón, 2000;Walker, Forrest, & Spooner, 2003;Rocha-Sánchez, Barrientos-Lozano, Zaldívar-Riverón, & Almaguer-Sierra, 2016;Heller et al, 2017).…”

“…The use of molecular markers, both nuclear and mitochondrial, have shed light on the phylogenetic relationships of a large number of insect groups at different taxonomic levels, including orthopterans (e.g. Mugleston, Song, & Whiting, 2013;Song, 2015;De Jesús-Bonilla et al, 2017;Kensinger, Schwemm, & Luttberg, 2017;Sanabria-Urbán et al, 2017;Grzywacz, Lehmann, Chobanov, & Lehmann, 2018). In this study we aimed to investigate the phylogenetic relationships among species of the eight representative genera that belong to the Dichopetala group to test both the monophyly of the group as well as of its genera.…”
