Authors: Ning Wang, Huateng Huang, Li-Bin Ma

Abstract: 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, Gymnogryllus Saussure, 1877 and Phonarellus Gorochov, 1983. We found that the characters (male genitalia in Gymnogryllus odonopetalus Xie & Zheng, 2003 and Phonarellus ritsemae (Saussure, 1877), and coloration of the hind leg in Phonarellus minor (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: G. yunnanensis (= G. odonopetalus) syn. nov., G. striatus (= G. odonopetalus) syn. nov., G. longus (= G. odonopetalus) syn. nov., G. tumidulus (= G. odonopetalus) syn. nov., and P. flavipes (= P. minor) syn. nov. All species mentioned above are described and illustrated. Keys and a distribution map are provided.

Flospes gen. nov. (Orthoptera, Trigonidiidae, Trigonidiinae), a genus of swordtail crickets from China, with two new species and new combinations https://zookeys.pensoft.net/article/77830/ ZooKeys 1090: 113-128

DOI: 10.3897/zookeys.1090.77830

Authors: Zhi-Xin He, Li-Bin Ma, Tao Zhang, Xiao-Lan Miao

Abstract: We propose the genus Flospes gen. nov. for two new species, Flospes guangxiensis sp. nov. and Flospes viridipennis sp. nov., obtained from Guangxi and Hainan provinces, China, respectively, based on male genitalia traits. Three other species with similar genitalia are placed in the new genus: Flospes fujianensis (Wang et al., 1999), comb. nov., Flospes hainanensis (He et al., 2010), comb. nov., and Flospes denticulatus (Liu & Shi, 2011), comb. nov. The new species are described, illustrated, and their ranges are given.

Qingryllus jiguanshanensis sp. n. from Sichuan, China, the second species of Qingryllus (Orthoptera, Gryllidae) https://zookeys.pensoft.net/article/11494/ ZooKeys 663: 65-70

DOI: 10.3897/zookeys.663.11494

Authors: Haoyu Liu, Dongxiao Zhang, Fuming Shi

Abstract: A second species of Qingryllus Chen & Zheng is described and illustrated, Q. jiguanshanensis sp. n., from Sichuan, China. This new species is similar to Q. striofemorus Chen & Zheng, 1995, but differs from the latter by the posterior margin of pronotum being distinctly widened, the veins of tegmina yellowish-white only on lateral side of dorsal area, and the epiphallus distinctly widened posteriorly. A distribution map of the species of this genus and habitus photographs of the new species are presented.

Geographic distribution of Gryllotalpa stepposa in south-eastern Europe, with first records for Romania, Hungary and Serbia (Insecta, Orthoptera, Gryllotalpidae) https://zookeys.pensoft.net/article/8804/ ZooKeys 605: 73-82

DOI: 10.3897/zookeys.605.8804

Authors: Ionuț Ștefan Iorgu, Elena Iulia Iorgu, Gellért Puskás, Slobodan Ivković, Simeon Borisov, Viorel Dumitru Gavril, Dragan Petrov Chobanov

Abstract: Described from the steppe zones north of the Black Sea, Caucasus, and central Asia, Gryllotalpa stepposa Zhantiev was recently recorded from a few localities in Greece, R. Macedonia, and Bulgaria. In May 2015, several specimens were collected from Ivrinezu Mare in Romania, which suggested a continuous distribution area of the species, stretching from the central Balkans to central Asia. Thus, to reveal its actual range of occurrence, a survey of several Orthoptera collections became mandatory and, as expected, a large number of misidentified specimens of Gryllotalpa stepposa were discovered, providing new data on the species distribution in south-eastern Europe, including also the first records of this mole cricket in Serbia and Hungary. Here a full locality list is presented of this species west of Ukraine and Moldova and the current geographic distribution of the genus Gryllotalpa in the Balkans is revised. A key for distinguishing the mole crickets in south-eastern Europe and a distribution map for this region are presented.

Taxonomic recovery of the ant cricket Myrmecophilus albicinctus from M. americanus (Orthoptera, Myrmecophilidae) https://zookeys.pensoft.net/article/7739/ ZooKeys 589: 97-106

DOI: 10.3897/zookeys.589.7739

Authors: Takashi Komatsu, Munetoshi Maruyama

Abstract: Myrmecophilus americanus and M. albicinctus are typical myrmecophilous insects living inside ant nests. These species are ecologically important due to the obligate association with tramp ant species, including harmful invasive ant species. However, the taxonomy of these “white-banded ant crickets” is quite confused owing to a scarcity of useful external morphological characteristics. Recently, M. albicinctus was synonymized with M. americanus regardless of the apparent host use difference. To clarify taxonomical relationship between M. albicinctus and M. albicinctus, we reexamined morphological characteristics of both species mainly in the viewpoint of anatomy. Observation of genitalia parts, together with a few external body parts, revealed that M. albicinctus showed different tendency from them of M. americanus. Therefore, we recover M. albicinctus as a distinct species on the basis of the morphology.

A new fossil cricket of the genus Proanaxipha in Miocene amber from the Dominican Republic (Orthoptera, Gryllidae, Pentacentrinae) https://zookeys.pensoft.net/article/3200/ ZooKeys 229: 111-118

DOI: 10.3897/zookeys.229.3678

Authors: Sam Heads, David Penney, David Green

Abstract: A new species of the cricket genus Proanaxipha Vickery & Poinar (Orthoptera: Gryllidae: Pentacentrinae) from Early Miocene Dominican amber is described and illustrated. Proanaxipha madgesuttonae sp. n. is distinguished from congeners by: (1) head capsule bearing a distinctive posteriorly bilobed colour spot on the vertex; (2) presence of crossveins in the proximal part of the mediocubital area; (3) apical field of tegmen entirely dark; and (4) median process of epiphallus short. The poorly known Proanaxipha bicolorata Vickery & Poinar, of questionable affinity and status, is herein regarded as a nomen inquirendum.

On the placement of the Cretaceous orthopteran Brauckmannia groeningae from Brazil, with notes on the relationships of Schizodactylidae (Orthoptera, Ensifera) https://zookeys.pensoft.net/article/2537/ ZooKeys 77: 17-30

DOI: 10.3897/zookeys.77.769

Authors: Sam Heads, Léa Leuzinger

Abstract: The fossil orthopteran Brauckmannia groeningae Martins-Neto (Orthoptera, Ensifera) from the Early Cretaceous Crato Formation of Brazil, currently misplaced at both the genus and family level, is transferred to the family Schizodactylidae and assigned to the extant genus Schizodactylus Brullé; ergo, Brauckmannia enters synonymy under Schizodactylus and Brauckmanniidae enters synonymy under Schizodactylidae. Schizodactylus groeningae (Martins-Neto), comb. n. agrees in size and general habitus with extant members of the genus, but can be readily separated by the robust, subovoid form of the metatibiae and the distinctive morphology of the lateral metabasitarsal processes. This species represents the first fossil occurrence of Schizodactylidae and the only New World record of this ancient lineage. Phylogenetic relationships of the schizodactylids are reviewed and a sister-group relationship with Grylloidea advocated based on a reappraisal of morphological and molecular evidence.
