biostudies-literatureUnknown1129Wang NAfter extensive sampling of specimens from species found in China, we examined the intraspecific morphological variation of several characters used for species delimitation in two closely related cricket genera, <i>Gymnogryllus</i> Saussure, 1877 and <i>Phonarellus</i> Gorochov, 1983. We found that the characters (male genitalia in <i>Gymnogryllusodonopetalus</i> Xie & Zheng, 2003 and <i>Phonarellusritsemae</i> (Saussure, 1877), and coloration of the hind leg in <i>Phonarellusminor</i> (Chopard, 1959)) exhibit considerable amounts of variation within species, and are thus not reliable characters for species differentiation. Therefore, we revised the taxonomy of these two genera. Five synonyms are proposed: <i>G.yunnanensis</i> (= <i>G.odonopetalus</i>) <b>syn. nov.</b>, <i>G.striatus</i> (ZooKeys85-107https://www.ebi.ac.uk/biostudies/studies/S-EPMC9836715biostudies-literatureThe intraspecific variation of morphology and coloration of field crickets: a taxonomic revision of Chinese <i>Gymnogryllus</i> Saussure, 1877 and <i>Phonarellus</i> Gorochov, 1983 (Orthoptera, Gryllidae, Gryllini).PMC9836715Wang NHuang HMa LBfalseThe intraspecific variation of morphology and coloration of field crickets: a taxonomic revision of Chinese <i>Gymnogryllus</i> Saussure, 1877 and <i>Phonarellus</i> Gorochov, 1983 (Orthoptera, Gryllidae, Gryllini).After extensive sampling of specimens from species found in China, we examined the intraspecific morphological variation of several characters used for species delimitation in two closely related cricket genera, <i>Gymnogryllus</i> Saussure, 1877 and <i>Phonarellus</i> Gorochov, 1983.
