Abstract: The genus Svistella Gorochov, 1987 includes 10 species from Asia, with nine documented in China. In this study, a new species, Svistella yayun He, sp. nov., is described from Xizang, China. Morphologically, it resembles S. rufonotata (Chopard, 1932) but can be distinguished by a smaller inner tympanum, dark-brown setae on the 5th segment of the maxillary palp, and a rounded apex on the ectoparamere. To validate our morphological inferences and support the description of S. yayun sp. nov. as a new species, we performed a PCA based on bioacoustics parameters and molecular analysis. All Svistella species documented in China are distinguished by integrating their songs and DNA barcoding.

On the specific status of Scelimena spicupennis and a new record of S. discalis from China with mitochondrial genome characterization (Orthoptera, Tetrigidae) https://zookeys.pensoft.net/article/110148/ ZooKeys 1185: 83-104

DOI: 10.3897/zookeys.1185.110148

Authors: Ying-Can Qin, Jing Liu, Xiao-Dong Li, Ya-Zhen Chen, Wei-An Deng

Abstract: The genus Scelimena Serville (Orthoptera: Tetrigidae) from China is reviewed. One species, Scelimena spicupennis Zheng & Ou, 2003 (China: Yunnan) is redescribed, and a new record of Scelimena discalis (Hancock, 1915) from China is given. An annotated identification key for Chinese species of the genus Scelimena is provided. Mitochondrial genes of S. spicupennis and S. discalis were sequenced and annotated. The sizes of the two sequenced mitogenomes are 17,552 bp (S. discalis), and 16,069 bp (S. spicupennis), respectively. All of the PCGs started with the typical ATN (ATT, ATC or ATG) or TTG codon and most ended with complete TAA or TAG codon, with the exception of the ND5 gene, which terminated with an incomplete T. The mitochondrial genomes for these two recorded species are provided, and the constructed phylogenetic tree supports their morphological taxonomic classification. The topology of the phylogenetic tree showed that three species of Scelimena were clustered into one branch and formed a monophyletic and a holophyletic group.

A review of Eupholidoptera (Orthoptera, Tettigoniidae) from Crete, Gavdos, Gavdopoula, and Andikithira https://zookeys.pensoft.net/article/97514/ ZooKeys 1151: 67-158

DOI: 10.3897/zookeys.1151.97514

Authors: Luc Willemse, Jos Tilmans, Nefeli Kotitsa, Apostolos Trichas, Klaus-Gerhard Heller, Dragan Chobanov, Baudewijn Odé

Abstract: Being nocturnal, hiding in prickly bushes and shrubs during the day, Eupholidoptera species in Crete and its neighbouring islands are easily overlooked, and until now our knowledge about their distribution was based on some thirty sightings across 11 species. In this paper results are presented of a study of Eupholidoptera specimens collected between 1987 and 2020 by hand-catches and pitfall and fermenting traps on the Greek islands of Crete, Gavdos, Gavdopoula, and Andikithira. Diagnostic features of all known species are presented and illustrated with stacked images. An updated key to all species is provided. Eupholidoptera francisae Tilmans & Odé, sp. nov. from Andikithira and southwestern Crete and Eupholidoptera marietheresae Willemse & Kotitsa, sp. nov. from Mt. Dikti are described. Female E. cretica, E. gemellata, and E. mariannae are described, and the female of E. astyla is redescribed. Bioacoustics for E. francisae Tilmans & Odé, sp. nov., E. giuliae, and E. jacquelinae are presented for the first time. Eupholidoptera smyrnensis is reported for the first time from Crete. A substantial amount of new distribution data for Eupholidoptera species on Crete is presented. The current distribution pattern and first analyses of phylogeny based on molecular data of Eupholidoptera species on Crete are discussed in relation to paleogeographical events.

The intraspecific variation of morphology and coloration of field crickets: a taxonomic revision of Chinese Gymnogryllus Saussure, 1877 and Phonarellus Gorochov, 1983 (Orthoptera, Gryllidae, Gryllini) https://zookeys.pensoft.net/article/87706/ ZooKeys 1129: 85-107

DOI: 10.3897/zookeys.1129.87706

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.

A DNA barcode library for katydids, cave crickets, and leaf-rolling crickets (Tettigoniidae, Rhaphidophoridae and Gryllacrididae) from Zhejiang Province, China https://zookeys.pensoft.net/article/86704/ ZooKeys 1123: 147-171

DOI: 10.3897/zookeys.1123.86704

Authors: Yizheng Zhao, Hui Wang, Huimin Huang, Zhijun Zhou

Abstract: Barcode libraries are generally assembled with two main objectives in mind: specimen identification and species discovery/delimitation. In this study, the standard COI barcode region was sequenced from 681 specimens belonging to katydids (Tettigoniidae), cave crickets (Rhaphidophoridae), and leaf-rolling crickets (Gryllacrididae) from Zhejiang Province, China. Of these, four COI-5P sequences were excluded from subsequent analyses because they were likely NUMTs (nuclear mitochondrial pseudogenes). The final dataset consisted of 677 barcode sequences representing 90 putative species-level taxa. Automated cluster delineation using the Barcode of Life Data System (BOLD) revealed 118 BINs (Barcodes Index Numbers). Among these 90 species-level taxa, 68 corresponded with morphospecies, while the remaining 22 were identified based on reverse taxonomy using BIN assignment. Thirteen of these morphospecies were represented by a single barcode (so-called singletons), and each of 19 morphospecies were split into more than one BIN. The consensus delimitation scheme yielded 55 Molecular Operational Taxonomic Units (MOTUs). Only four morphospecies (Imax > DNN) failed to be recovered as monophyletic clades (i.e., Elimaea terminalis, Phyllomimus klapperichi, Sinochlora szechwanensis and Xizicus howardi), so it is speculated that these may be species complexes. Therefore, the diversity of katydids, cave crickets, and leaf-rolling crickets in Zhejiang Province is probably slightly higher than what current taxonomy would suggest.

Geographic differentiation in male calling song of Isophya modestior (Orthoptera, Tettigoniidae, Phaneropterinae) https://zookeys.pensoft.net/article/85721/ ZooKeys 1122: 107-123

DOI: 10.3897/zookeys.1122.85721

Authors: Slobodan Ivković, Dragan Chobanov, Laslo Horvat, Ionuț Ștefan Iorgu, Axel Hochkirch

Abstract: We studied the songs and morphology of the stridulatory file of Isophya modestior across its complete geographic range, in order to test our hypothesis that the male calling song of the species shows strong differentiation between the northern (Pannonian) and southern (Balkan) parts of its distribution range, reflecting its disjunct distribution. Our analyses confirm this hypothesis, separating analyzed specimens of I. modestior into two main groups - one present in the central part of the Balkan Peninsula (representing Isophya modestior sensu stricto), with the second group occurring in the Pannonian Basin, Dinarides, Slovenia and NE Italy. The most reliable difference between the groups is the duration of the main syllable, the number of stridulatory teeth and number of pulses in the main syllable, where all values are higher in specimens from the Balkan Peninsula. Additional analyses showed that within the second group, there are differences in analyzed characters between specimens from the Pannonian Basin and specimens from the Dinaric area, the latter ones having intermediate song characteristics, closer to the group from the Balkan Peninsula. Our study shows that detailed bioacoustic analyses can help to unravel patterns of intraspecific differentiation and thus provide a useful tool for taxonomic studies.

DOI: 10.3897/zookeys.1078.75499

Authors: Muzamil Syed Shah, Mohd Kamil Usmani

Abstract: The Phaneropterinae, commonly known as the bush katydids, are among the most diverse tettigoniids in the world. A new species Anormalous liu sp. nov. is described from Kashmir, India. This is the second species in the short-winged genus Anormalous. It is differentiated from the other species from China by the absence of posterior apical spurs on the fore and mid tibiae, the male subgenital plate with two long cylindrical lobes fused with each other and blunt at the apices, and the male stridulatory area longer than broad. We include a key to species in the genus Anormalou. The holotype has been deposited in the Museum of Zoology Department, Aligarh Muslim University, Aligarh Uttar Pradesh, India.

Revision of the Afrotropical genus Leiodontocercus (Orthoptera, Tettigoniidae, Phaneropterinae) with a description of four new species https://zookeys.pensoft.net/article/53814/ ZooKeys 951: 47-65

DOI: 10.3897/zookeys.951.53814

Authors: Bruno Massa

Abstract: Specimens belonging to the genus Leiodontocercus are rare or even absent in natural history museum collections; this is likely due to at least two reasons, notably, their relatively small size, and, the sheer difficulty in finding them in dense Afrotropical forests. Until recently, three species from less than fifteen specimens were known from this genus, whose identification relied on a singular diagnostic character, that is, the shape of the male cerci. The present contribution is based on the examination of thirty specimens collected from various countries, ranging from central to west Africa; apart from the male cerci, a second diagnostic character – the stridulatory file – is used to distinguish species, even though it is difficult to examine in mounted specimens. As a result, four new species were detected, namely, L. vicii sp. nov., L. spinicercatus sp. nov. (from the Central African Republic), L. muticus sp. nov. (from Gabon and Cameroon) and L. philipporum sp. nov. (from Côte d’Ivoire). Moreover, L. condylus is recorded from the Central African Republic, the only country where three species of this genus co-occur. It is suggested that population isolation during fluctuating humid and dry periods, consequent to the influence of Ice Age impact during the Pleistocene in tropical central Africa, is the best explanation for the adaptive radiation of the group.

Island mysteries in the spotlight: Barbitistes kaltenbachi and Rhacocleis buchichii, the only bush-cricket species endemic to Croatia (Orthoptera, Tettigoniidae) https://zookeys.pensoft.net/article/51599/ ZooKeys 936: 25-60

DOI: 10.3897/zookeys.936.51599

Authors: Rob Felix, Klaus-Gerhard Heller, Baudewijn Odé, Fran Rebrina, Josip Skejo

Abstract: Hvar Saw Bush-cricket Barbitistes kaltenbachi Harz, 1965 (Phaneropterinae: Barbitistini) and Lesina Bush-cricket Rhacocleis buchichii Brunner von Wattenwyl in Herman 1874 (Tettigoniinae: Platycleidini) are flightless orthopterans restricted to a narrow area in the Mediterranean part of Croatia, both originally described from Hvar Island. In this study, all available information on these two interesting species is presented: data on morphology, bioacoustics, distribution, habitat, and a key to identification of the species belonging to genera Barbitistes and Rhacocleis in Croatia. The songs of both B. kaltenbachi and R. buchichii are described here for the first time, with the former one being the second known example of a synchronising and presumably duetting species. Both species were reassessed according to the IUCN Red List criteria, where B. kaltenbachi should be considered an endangered species, while R. buchichii is suggested to be downgraded to a less threatened category. Biogeography and evolution of the species are briefly discussed.

The complete mitochondrial genome of Xizicus (Haploxizicus) maculatus revealed by Next-Generation Sequencing and phylogenetic implication (Orthoptera, Meconematinae) https://zookeys.pensoft.net/article/24156/ ZooKeys 773: 57-67

DOI: 10.3897/zookeys.773.24156

Authors: Mao Shaoli, Yuan Hao, Lu Chao, Zhou Yafu, Shi Fuming, Wang Yuchao

Abstract: Xizicus Gorochov, 1993, the quiet-calling katydid, is a diverse genus with 68 species in world, which includes more than 45 species in China, has undergone numerous taxonomic revisions with contradicting conclusions. In this study the complete mitochondrial genome of Xizicus (Haploxizicus) maculatus collected from Hainan for the first time was sequenced using the Next-Generation Sequencing (NGS) technology. The length of whole mitogenome is 16,358 bp and contains the typical gene arrangement, base composition, and codon usage found in other related species. The overall base composition of the mitochondrial genome is 37.0 % A, 32.2 % T, 20.2 % C, and 10.6 % G. All 13 protein-coding genes (PCGs) began with typical ATN initiation codon. Nine of the 13 PCGs have a complete termination codon, but the remaining four genes (COI, COIII, ND5, and ND4) terminate with an incomplete T. Phylogenetic analyses are carried out based on the concatenated dataset of 13 PCGs and two rRNAs of Tettigoniidae species available in GenBank. Both Bayesian inference and Maximum Likelihood analyses recovered each subfamily as a monophyletic group. Regardless of the position of Lipotactinae, the relationships among the subfamilies of Tettigoniidae were as follows: ((((Tettigoniinae, Bradyporinae) Meconematinae) Conocephalinae) Hexacentrinae). The topological structure of the phylogeny trees showed that the Xizicus (Haploxizicus) maculatus is closer to Xizicus (Xizicus) fascipes than Xizicus (Eoxizicus) howardi.

High-speed duetting – latency times of the female acoustic response within the bush-cricket genera Leptophyes and Andreiniimon (Orthoptera, Phaneropteridae) https://zookeys.pensoft.net/article/23874/ ZooKeys 750: 45-58

DOI: 10.3897/zookeys.750.23874

Authors: Klaus-Gerhard Heller, Olga Korsunovskaya, Bruno Massa, Ionuț Ștefan Iorgu

Abstract: To find a mate, male and female bush-crickets of the family Phaneropteridae typically engage in duets. The male sings and the female responds. For mutual recognition, the amplitude pattern of the male song and the species-specific timing of the female response have been shown to be very important. In the seven studied species, belonging to the genera Leptophyes and Andreiniimon, these duets are extremely fast and nearly completely in the ultrasonic range. The females produce very short sounds by fast closing movements of the tegmina. They respond with species-specific delays of 20 to 150 ms after the beginning of the male song. The different latency times are probably not important for species recognition, since in sympatric species they are quite similar.

Isolated populations of the bush-cricket Pholidoptera frivaldszkyi (Orthoptera, Tettigoniidae) in Russia suggest a disjunct area of the species distribution https://zookeys.pensoft.net/article/12339/ ZooKeys 665: 85-92

DOI: 10.3897/zookeys.665.12339

Authors: Peter Kaňuch, Martina Dorková, Andrey P. Mikhailenko, Oleg A. Polumordvinov, Benjamín Jarčuška, Anton Krištín

Abstract: Phylogenetic analysis and assessment of the species status of mostly isolated populations of Pholidoptera frivaldszkyi in south-western Russia occurring far beyond the accepted area of the species distribution in the Carpathian-Balkan region were performed. Using the mitochondrial DNA cytochrome c oxidase subunit I gene fragment, we found a very low level of genetic diversity in these populations. Phylogeographic reconstruction did not support recent introduction events but rather historical range fragmentation. The grouping of the Russian and Romanian haplotypes in a distinct phylogenetic clade suggests that the pre-glacial range of P. frivaldszkyi had extended towards the Ponto-Caspian region, with considerable gene flow between different refugia. However, post-glacial northward expansion of the species from supposed Caucasus refugia contributed most likely to the current disjunct distribution of this relict-like bush-cricket.

The identity of the tropical African Polichne mukonja Griffini, 1908 (Orthoptera, Tettigoniidae, Phaneropterinae) https://zookeys.pensoft.net/article/9725/ ZooKeys 621: 37-44

DOI: 10.3897/zookeys.621.9725

Authors: Bruno Massa

Abstract: Polichne mukonja Griffini, 1908 from Cameroon was hitherto known only from the holotype preserved at the Royal Belgian Institute of Natural Sciences, Brussels. This was probably due to the fact that the genus Polichne Stål, 1874 distributed only in Australia and Papua New Guinea. In view of this distribution, the tropical African species was therefore overlooked in the African literature. The recent discovery of two specimens at the Naturhistorisches Museum, Vienna, now provides us with a better understanding of the identity of this taxon, which is related to the African genus Catoptropteryx Karsch, 1890. Polichne mukonja is here transferred to a new genus Griffinipteryx and both taxa are proposed to be included in the new tribe Catoptropterigini.

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.

DNA Barcoding of genus Hexacentrus in China reveals cryptic diversity within Hexacentrus japonicus (Orthoptera, Tettigoniidae) https://zookeys.pensoft.net/article/8669/ ZooKeys 596: 53-63

DOI: 10.3897/zookeys.596.8669

Authors: Hui-Fang Guo, Bei Guan, Fu-Ming Shi, Zhi-Jun Zhou

Abstract: DNA barcoding has been proved successful to provide resolution beyond the boundaries of morphological information. Hence, a study was undertaken to establish DNA barcodes for all morphologically determined Hexacentrus species in China collections. In total, 83 specimens of five Hexacentrus species were barcoded using standard mitochondrial cytochrome c oxidase subunit I (COI) gene. Except for H. japonicus, barcode gaps were present in the remaining Hexacentrus species. Taxon ID tree generated seven BOLD’s barcode index numbers (BINs), four of which were in agreement with the morphological species. For H. japonicus, the maximum intraspecific divergence (4.43%) produced a minimal overlap (0.64%), and 19 specimens were divided into three different BINs. There may be cryptic species within the current H. japonicus. This study adds to a growing body of DNA barcodes that have become available for katydids, and shows that a DNA barcoding approach enables the identification of known Hexacentrus species with a very high resolution.

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.

First song descriptions of some Anatolian species of Tettigoniidae Krauss, 1902 (Orthoptera, Ensifera) https://zookeys.pensoft.net/article/3212/ ZooKeys 369: 1-24

DOI: 10.3897/zookeys.369.5864

Authors: Deniz Şirin, Mehmet Taylan, Abbas Mol

Abstract: Fourteen endemic and two sub-endemic species belonging to three subfamilies of Tettigoniidae (Tettigoniinae, Bradyporinae and Saginae) were sampled during field trips throughout the different ranges of Anatolia between the years of 2004 and 2013. Acoustic parameters of these 16 species affiliated to 8 genera (Anterastes, Apholidoptera, Gampsocleis, Parapholidoptera, Pezodrymadusa, Psorodonotus, Bradyporus and Saga) have been described for the first time in this study. Acoustical analysis showed that song characters are species-specific in the genera Saga and Psorodonotus. On the other hand, we could not find big differences among species of the genus Pezodrymadusa and Parapholidoptera castaneoviridis species-group.

Molecular systematics of the genus Troglophilus (Rhaphidophoridae, Orthoptera) in Turkey: mitochondrial 16s rDNA evidences https://zookeys.pensoft.net/article/3619/ ZooKeys 257: 33-46

DOI: 10.3897/zookeys.257.4133

Authors: Mehmet Taylan, Claudio Di Russo, Mauro Rampini, Valerio Ketmaier

Abstract: This study focuses on the evolutionary relationships among Turkish species of the cave cricket genus Troglophilus. Fifteen populations were studied for sequence variation in a fragment (543 base pairs) of the mitochondrial DNA (mtDNA) 16S rDNA gene (16S) to reconstruct their phylogenetic relationships and biogeographic history. Genetic data retrieved three main clades and at least three divergent lineages that could not be attributed to any of the taxa known for the area. Molecular time estimates suggest that the diversification of the group took place between the Messinian and the Plio-Pleistocene.

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.

Four new species of Dolichopoda Bolivar, 1880 from Southern Sporades and Western Turkey (Orthoptera, Rhaphidophoridae, Dolichopodainae) https://zookeys.pensoft.net/article/2853/ ZooKeys 201: 43-58

DOI: 10.3897/zookeys.201.2609

Authors: Mauro Rampini, Claudio Di Russo, Mehmet Taylan, Arianna Gelosa, Marina Cobolli

Abstract: A description of four new species of Dolichopoda Bolivar, 1880 (Orthoptera, Rhaphidophoridae) from Eastern Aegean region (Southern Sporades), including Western Turkey, is reported. This brings to a total of 11 the number of Dolichopoda species recorded for caves of the Aegean area. Overall, these species show a high degree of morphological homogeneity and they are very close to D. paraskevi Boudou-Saltet, 1973 from Crete and D. naxia Boudou-Saltet, 1972 from Cyclades (Naxos Island). The Western Turkish species are morphologically not closely related to the other Anatolian species; this suggests an independent origin for the taxa occurring in the Southern Taurus and Black Sea regions. These new data help to better define the already high level of diversity of the Hellenic Dolichopoda and strengthen the hypothesis that the central area of dispersal for the genus would correspond to the ancient Aegean plate.

Ethanol fuel improves arthropod capture in pitfall traps and preserves DNA https://zookeys.pensoft.net/article/2809/ ZooKeys 196: 11-22

DOI: 10.3897/zookeys.196.3130

Authors: Neucir Szinwelski, Verônica Fialho, Karla Yotoko, Léon Seleme, Carlos Sperber

Abstract: We tested the value of ethanol fuel as a killing solution in terms of sampling efficiency (species richness and accumulated abundance) and DNA preservation of Ensifera ground-dwelling specimens. Sampling efficiency was evaluated comparing abundance and species richness of pitfall sampling using 100% ethanol fuel, with two alternative killing solutions. We evaluated the DNA preservation efficiency of the killing solutions and of alternative storage solutions. Ethanol fuel was the most efficient killing solution, and allowed successful DNA preservation. This solution is cheaper than other preserving liquids, and is easily acquired near field study sites since it is available at every fuel station in Brazil and at an increasing number of fuel stations in the U.S. We recommend the use of ethanol fuel as a killing and storage solution, because it is a cheap and efficient alternative for large-scale arthropod sampling, both logistically and for DNA preservation. For open habitat sampling with high day temperatures, we recommend doubling the solution volume to cope with high evaporation, increasing its efficacy over two days.

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.
