Abstract
Only one species of Pendleburyella Chopard, 1969 (Gryllidae, Pentacentrinae) was previously known to occur in Borneo: Pendleburyella eirmosa Tan, Muhammad & Wahab, 2023 from Brunei Darussalam. Here, two additional new species of crickets from the genus Pendleburyella are described from the highlands of Sabah, Borneo: Pendleburyella eremita sp. nov. from Bukit Hampuan and Pendleburyella nimba sp. nov. from Mount Trus Madi. In total, six species of Pendleburyella are currently known, three from Borneo and three from Malay Peninsula. It is likely that many more species are awaiting discovery owing to its cryptic morphology and elusive nature.

[Entomology • 2024] Miripella & Arrakis gen. nov. • Museomics, Molecular Phylogeny and Systematic Revision of the Eurepini Crickets (Orthoptera: Gryllidae: Eneopterinae), with Description of Two New Genera

Abstract
Natural history collections worldwide house billions of specimens, representing one of the most globally important biobanks. In recent years, the advent of next-generation sequencing has significantly reduced the challenges of obtaining considerable genetic information from historical museum specimens. Crickets in the Australian tribe Eurepini Robillard are a good example of a taxon in which such museomic data have particularly strong potential to advance systematic knowledge, because comprehensive sampling requires decades of work over a very wide area. The tribe currently comprises 64 described species in five genera. Previous studies conflict in the generic relationships inferred for this tribe, all of which are poorly resolved, being based on limited data and sampling. In addition, there has so far been no systematic research for this tribe with extensive taxon sampling, and therefore, the consequence for genus boundaries remains to be investigated. To investigate phylogenetic relationships within Eurepini, we first applied the genome skimming approach to obtain molecular data from a comprehensive sample of Eurepini museum specimens. Of the 69 specimens sampled representing 61 described species, mainly including holotype specimens, we obtained 50 complete and 11 partially complete mitogenomes. Three nuclear genes (H3, 18S, and 28S) were also partially recovered for nearly all of these specimens. Phylogenetic analyses performed with mitogenomes plus three nuclear genes using maximum likelihood and Bayesian inference generated well-supported and highly congruent topologies. Eurepini was strongly recovered monophyletic with eight well-defined groups. These groups are used to revise the systematics of the tribe based on a combination of molecular phylogenetics and morphology. The phylogenetic results support the current definition of three genera (Eurepa Walker, Arilpa Otte & Alexander and Eurepella Otte & Alexander), lead us to redefine three genera (Salmanites Chopard, Napieria Baehr and Piestodactylus Saussure), and define and describe two new generaMiripella Robillard, Tan & Su gen. nov. and Arrakis Robillard, Tan & Su gen. nov. Our results reinforce the importance of natural history collections as a repository for information on biodiversity and genetics, and provide the first comprehensive and robust phylogenetic framework for future systematic and evolutionary studies of Eurepini.

[Entomology • 2022] Indigryllus sagani • A New Species of Indigryllus (Orthoptera: Gryllidae: Eneopterinae: Xenogryllini) from Kerala, India, with First Data on Acoustics and Natural Habitat


Indigryllus sagani
Jaiswara, Sreebin, Monaal & Robillard, 2022

 
Abstract
In India, the cricket subfamily Eneopterinae is represented by two known genera, Xenogryllus Bolívar, 1890 and Indigryllus Robillard & Jaiswara, 2019. The latter was recently described and is known from a single species I. kudremu Robillard & Jaiswara, 2019 from Karnataka, India. The species was known exclusively from its morphological features and there existed no information on its biology and acoustic features. The present study is a step ahead in understanding the natural history and acoustic signalling in the genus. Based on a collaboration initiated by citizen science observations on the website iNaturalist, we describe a new species, Indigryllus sagani sp. nov. from Kerala, India, with details on its habitat and acoustic signals.

[Entomology • 2022] Oecanthus beameri • A New Species of Tree Cricket (Orthoptera: Gryllidae: Oecanthinae) from Chihuahuan Desert Gypsum Dunes in the United States and A Key to the nigricornis Species Group


Oecanthus beameri  
Collins & Lightfoot, 2022


Abstract
A new species of tree crickets, Oecanthus beameri sp. nov., is described from the gypsum dunes of White Sands National Park in New Mexico, United States. The new species is currently known only from the type locality, where it appears to be specific to the gypsophile plant hoary rosemary mint (Poliomintha incana). This new species has the narrowed tegmina and calling song that are found in the nigricornis species group. Although it has morphological similarities to O. quadripunctatus and O. celerinictus, there are differences in the subgenital plates, tegminal measurements, coloring, tibial markings, song frequency, and song pulse rate. This new species has been given the common name White Sands tree cricket. We provide a key to all species in the nigricornis group. Video and song recordings are available online as Suppl. materials 1–8.

 Oecanthus beameri sp. nov.
 
Diagnosis.— The antennal markings of O. beameri sp. nov. can total two, three, or four, with the medial mark on the scape usually broken into two pieces (Figs 3C, 4), while O. quadripunctatus has either two or four marks with the medial mark on the scape being a solid post, and O. celerinictus always has a solid medial mark on the scape and never lacks the upper outer mark on the scape and is never round. The two antennal marks on the pedicel of O. walkeri (Collins and Symes 2012) touch, and those of O. argentinus touch or nearly touch, while the marks on O. beameri sp. nov. do not.
 
Etymology.— Specific epithet in recognition of Raymond Beamer who collected the specimens in 1932 that were discovered in the ANSDU collection in 2019. The common name, White Sands tree cricket, is for the location where this species was discovered with high potential for endemism.

Abstract
Brachypterous crickets from the monophyletic group of Lebinthina were traditionally grouped under the genus Lebinthus. However, the morphology and calling song are highly diversified, prompting the erection of numerous genera to reclassify the species. Based on the strong characteristic fold carrying the diagonal vein of the male forewing, a new genus of cricket from the subtribe Lebinthina is described: Rugabinthus gen. nov. This brachypterous genus is endemic to the island of New Guinea and nearby islands. We redescribe the type species Rugabinthus leopoldi (Chopard, 1931) comb. nov. and describe 12 new species, R. manokwari sp. nov., R. kencana sp. nov., R. maoke sp. nov., R. nabire sp. nov., R. albatros sp. nov., R. karimui sp. nov., R. yayukae sp. nov., R. biakis sp. nov., R. mamberamo sp. nov., R. tariku sp. nov., R. faowi sp. nov., and R. baduri sp. nov. We also transferred R. newguineae (Bhowmik, 1981) comb. nov. and provide a key to all known species of Rugabinthus gen. nov.

Type species.— Lebinthus leopoldi Chopard, 1931

Diagnosis.— Among the Lebinthina genera, Rugabinthus species are average to large sized and stocky with a dark brown coloration. General shape close to that of Macrobinthus, also from New Guinea, from which it differs by male FWs with a narrow triangular harp (shield shaped in Macrobinthus) occupying half of FW width, with a characteristic and strong diagonal fold carrying the diagonal vein and cell c1, and separating FWs in two distinct areas; file vein area also characterized by a strong bean-shaped sclerotization; harp with a strong transverse oblique vein, bi- or poly-furcated anteriorly; venation posterior to diagonal fold usually faint and reticulated, longitudinal veins only strong at apex. Eyes prominent and large as in Macrobinthus compared to Agnotecous and Centuriarus; face as high as wide (higher than wide in Macrobinthus), close to that of Lebinthus. Microptery in both sexes, FWs not reaching mid-length of abdomen. Mirror not differentiated (slightly differentiated in Macrobinthus). CuA almost straight (clearly curved inwards in Macrobinthus). Male genitalia with pseudepiphallus usually elongate, its posterior apex highly variable in size and shape, rami short; pseudepiphallic parameres made of two main lobes variable in shape and orientation; endophallic sclerite very long, trifid posteriorly. Female: FWs shorter than in males, very slightly overlapping, generally rounded posteriorly. Ovipositor rather long, its apex slightly denticulate on dorsal edge. Female copulatory papilla usually rounded, with a C-shaped basal sclerite; apex rounded, generally folded ventrally.

[Entomology • 2020] Pseudolebinthus lunipterus • A Striking Deaf and Mute New Cricket (Orthoptera, Gryllidae, Eneopterinae) from Malawi


Pseudolebinthus lunipterus 
 Salazar, Murphy, Guillaume, Nattier & Robillard, 2020 

Abstract
This article presents an intriguing new cricket species of the tribe Xenogryllini discovered in Northern Malawi. This is the first case of mute and deaf species in the subfamily Eneopterinae; it shows no stridulatory apparatus on short male forewings and no tympana on either side of fore tibiae in both sexes. We introduce the new species and its complete mitogenome and assess phylogenetic relationships based on molecular data obtained from next-generation sequencing genome skimming method. Phylogenetic analyses place the new species within the genus Pseudolebinthus in Xenogryllini, as the sister species of Pseudolebinthus gorochovi Robillard. We describe Pseudolebinthus lunipterus sp. nov., provide illustrations of main morphology, male and female genitalia, photographs of living specimens and information about habitat and update the identification key for species of genus Pseudolebinthus. We discuss the differences between the new species and related taxa and the striking loss of acoustic communication in this cricket.

Pseudolebinthus lunipterus sp. nov.

Diagnosis: Size small, mostly dark brown with pale wings (Figs. 1, 3 and 4). Among Eneopterinae genera, the new species presents the characteristics of Pseudolebinthus: large lateral eyes (Figs. 5A–5C); brachypterous FWs barely reaching quarter of abdomen length in males (Figs. 4 and 6), shorter in females where it forms pale narrow crescents (Figs. 4 and 5D); male genitalia with long sclerotized lophi, close to that of P. gorochovi (Figs. 8 and 9); female ovipositor little differentiated but less pointed and thicker than in P. gorochovi (Fig. 10A). The new species is characterized by complete absence of tympana (unique feature among eneopterines) (Figs. 7A and 7B), absence of stridulatory apparatus on male FWs (Fig. 6), abdomen ventrally yellow with a wide black stripe (Fig. 5F), thick and short female ovipositor (Fig. 4D), and differences in male genitalia, including shape of pseudepiphallic parameres, shape of sclerite in ectophallic fold and endophallic apodeme with anterior lateral expansions.

Type locality. North Malawi, Mount Uzumara, ..., 1,941 m.

Distribution. The species is only known from the type locality in Northern Malawi (Fig. 1C).

Etymology. The species name refers to the whitish wings, rounded in males and crescent-shaped in females, which look like tiny moons on the back of the dark body of these crickets when encountered at night.

Habitat and life history. Pseudolebinthus lunipterus lives on low vegetation in herbaceous areas near forest hedge or in open areas along trails in forest (Figs. 1A and 1B). Adults and juveniles have been found active at night on top of vegetation, but can also be found lower within vegetation during the day. Remarkably, the species lives in syntopy with P. gorochovi in the type locality, where adults and juveniles of both species are quite abundant. One juvenile specimen of P. lunipterus has been observed eating a dead insect on a low leaf on vegetation (Fig. 11B).

Females maintained in controlled laboratory conditions (20–22 °C, 14–10 day–night cycle) with a single male produced 46–50 offspring (n = 2) during their life; first hatchings started 42–49 days after first mating and occurred on a period of 35–66 days.

Conclusion: Crickets of Malawi
The diversity of crickets in Eastern Africa in general, and Malawi in particular, has been underestimated, understudied and undersampled. This is at least the case for the members of the tribe Xenogryllini which were recently revised (Jaiswara, Dong & Robillard, 2018, 2019; Jaiswara et al., 2019). Despite the large amount of data considered in these systematic studies (several hundreds of specimens studied across the study of the largest natural history museum collections), they gathered very little information about the species of Pseudolebinthus, known by a few specimens each.

A single recent field trip in Malawi allowed us to re-discover two of the previously described species of the genus, which are in fact common species, and it allowed documenting the acoustic features of their calling songs and their ecology (T. Robillard et al., 2020, in prep.). Interestingly, these findings allowed us to discover P. lunipterus, a completely different new species belonging to the Xenogryllini lineage, but with strikingly new morphological features. This finding reveals that more taxa probably remain unrecorded in the whole Eastern African region, as suggested by the large amount of new species and genera recently discovered in this region for other clades of orthopteran insects (Hemp et al., 2018; Hemp & Heller, 2019). More taxonomic surveys with appropriate collecting methods in regions where there is zero record about these crickets, such as other regions of Malawi, but also Zimbabwe, Zambia, Western Mozambique and Northern South Africa, are thus necessary to explore this part of African biodiversity.

[Entomology • 2019] Endodrelanva siargaoensis • A New Species of Landrevinae (Orthoptera) from the Philippines, with Notes on Endodrelanva and Endolandrevus (Orthoptera: Gryllidae; Gryllinae; Landrevini)

 Kai, Gorochov, Baroga-Barbecho & Yap, 2019


Abstract
Owing to the cryptic behavior and morphology of many Southeast Asian Landrevinae, new species are still being discovered in unexplored parts of the region. Here, we describe a new species: Endodrelanva siargaoensis sp. nov. We also recorded and describe the calling song of the new species. Owing to the morphological similarities between species of Endodrelanva Gorochov, 2000 and Endolandrevus Saussure, 1877, we also provide a short review of the two genera and list their characters for comparison.

Keywords: Orthoptera, bioacoustics, biogeography, Grylloidea, Southeast Asia, taxonomy

[Entomology • 2018] Scapsipedus icipe • A New Edible Cricket Species of the Genus Scapsipedus (Orthoptera: Gryllidae) from Kenya, Africa


 Scapsipedus icipe Hugel & Tanga, 2018


 in Tanga, Magara, Ayieko, et al., 2018. 

Abstract
A new cricket of the genus Scapsipedus is described from Kenya. The distribution, acoustic behavior, including call and courtship song, mitochondrial sequences, and data on the biology of that new species are given. This edible cricket is a very promising species for mass production for food and feed.

Keywords: Orthoptera, new species, bioacoustics, insect farming

[Entomology • 2018] A New Status for Aclogryllus Gorochov, 2009 (Phalangopsidae; Phalangopsinae) with A New Species, Aclogryllus manauensis, from Brazilian Amazon


Aclogryllus manauensis da Silva & Martins

in da Silva, Martins, Pereira & Henriques, 2018

Abstract 
In this work, we propose to raise the subgenus Aclogryllus to generic status based on characteristics of external morphology and male genitalia. A new Amazonian species of Aclogryllus is also described. Photographs of nomenotypic species and the new Amazonian species are provided along with the description of morphological characteristics, diagnosis and photographs of male genitalia and female copulatory papilla.
