Type specimens carry valuable information that can facilitate biodiversity research, especially in an era of mass extinction and unprecedent anthropogenic climate change. For Orthoptera, a few initiatives, including the Orthoptera Species File digitization collections by numerous museums, have helped to make images about type available on World Wide Web. However, many local collections, those from poorly studied regions Southeast Asia, are still not public. The collection Grylloidea...

Three species new to science of the Gryllid subfamilies Gryllinae and Pteroplistinae are described from Brunei: (1) Mimicogryllus splendens Tan, Gorochov & Wahab, sp. nov., (2) Pteroplistes bruneiensis (3) Tembelingiola belaitensis nov. A cricket subfamily Phaloriinae is also Sandakan, eastern Sabah: Vescelia sepilokensis Gorochov, Japir Chung,

Orthoptera from Sandakan, Sabah are relatively understudied compared to some other parts of Borneo, and lack information species there can impede our understanding the origins biodiversity orthopterans in Borneo and, general, Southeast Asia. Based on a recent orthopteran survey one new Lebinthus Stål is described: sandakan sp. nov. The male calling song this also presented. Cardiodactylus borneoe Robillard & Gorochov, 2014 described for first time.

Rhicnogryllus Chopard, 1925 is a small and relatively unknown group of Sword-tailed Cricket the subfamily Trigonidiinae. This genus currently comprises 12 species from Asia, Africa (including Madagascar), South America Pacific. Species have been recognised by presence parallel elevated veins in both males (which lack stridulatory organs) females. However, this approach to classifying Trigonidiinae may be outdated examination male genitalia can offer better insights into generic status these...

Nisitrus Saussure, 1878 is a diurnal and monophyletic group of eneopterine crickets found in parts Southeast Asia. Species often have vivid colourations which make them charismatic photograph subjects among macro photographers. However, their taxonomy has not been revised since original descriptions, whereas there are also species awaiting to be discovered described. A synoptic revision therefore needed prior studying the phylogenetic relationships genus, before undertaking more precise...

Recent orthopteran surveys in the hyper-diverse Borneo, i.e., Brunei Darussalam and Sandakan Sabah, allow us to review scaly crickets from subfamily Mogoplistinae there. We discover describe male, as well formally naming Cycloptiloides bimaculata Tan, Japir Chung, sp. nov. Sandakan. This species was previously described 1 a comprehensive revision by Ingrisch (2006) but only females were known. also Ectatoderus nigrofasciatus Tan Wahab, Darussalam. New locality records are reported for...

Abstract The Lebinthini crickets are distributed in Southeast Asia, Western Pacific and tropical South America. They represent more than half of the described species subfamily Eneopterinae. These morphologically behaviorally diverse, varying body size, wing morphology (ranging from brachypterous to fully winged) acoustic signals. also have a distinctive communication system: high‐frequency calling, vibratory signalling, duetting, lack phonotaxis females. To investigate how these traits...

Based on recent sampling of orthopterans in Maliau Basin and Meligan (including near Long Pasia Sinipung Hill), Sabah, Borneo, we present here notes some the katydids from subfamily Phaneropterinae. Two new species were discovered are described: Tapiena dimidia sp. nov. munae Hill Meligan. New locality records for Elbenia (Elbenia) paradigitata Gorochov, 2023, Stictophaula multa Gorochov & Voltshenkova, 2009, Holochlora falcata Tan, Liu Ingrisch, 2024 possibly Psyrana (Psyrana) nr. imitativa...

Flower visitation by orthopterans, particularly taxa from Southeast Asia, was only recently brought to light in a report on the diversity and network of 41 orthopteran Asia visiting flowers 35 plant taxa. Continued efforts document flower orthopterans have led 104 new incidences including 17 A total 247 58 flower-visiting 71 genera are reported here. In accordance with previous studies, subfamily Phaneropterinae remains most prominent is very likely undisputedly floriphilic. Using dataset...

Based on an orthopteran survey in different parts of western Sabah, a total 24 species from 16 genera are reported here, i.e., three one genus Elimaeini, 14 nine Holochlorini and two Mirolliini. Among them, four Holochlora new to science described Mount Trus Madi: bulbosa Tan, Liu & Ingrisch, sp. nov., falcata bispinosa nov. cratera One is Pulchrapsyra cyanea gen. et Deflorita (Separita) Madi described: extensa

A new species of Itara (Phormincter) is described from Mindanao in the Philippines: mindanao Tan, Grumo, Gono & Bahoy, sp. nov. This represents first record this subgenus Philippines, having previously known only Borneo, Java, Malay Peninsula and Sumatra; as well second Philippines Island. The male calling song holotype was also recorded here. Additionally, another congener, (Singitara) singularis Gorochov, 1997 Sabah, (Bornitara) Sabah Borneo: tenompok Japir Chung,

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

Katydids produce sound for signaling and communication by stridulation of the tegmina. Unlike crickets, most katydids are known to sing at ultrasonic frequencies. This has drawn interest in investigation biophysics production, detection, evolution, ecology (including predator–prey interactions) these katydids. However, studies based on species from Neotropics, while little is about katydid hyperdiverse region Southeast Asia. To address this, a concerted effort document, record, describe...

From the eastern parts of Sabah, four new species crickets are described, two which from subfamily Landrevinae and Podoscirtinae: Duolandrevus (Duolandrevus) nobilis sp. nov. Odontogryllodes spinifer nov.; Brevimunda trilineata Varitrella (Cantotrella) tabin nov., respectively. We also describe calling songs for three species: (Bejorama) lambir Gorochov, 2017, A locality record (Sabah, Sepilok) previously known western Borneo (Sarawak, Lambir Hill Brunei Darussalam, Kuala Belalong), was reported.

Lipotactinae is an elusive monophyletic subfamily of katydids (Orthoptera: Tettigoniidae) unique to Asia and comprising two genera – Lipotactes Mortoniellus. Nearly nothing known beyond their original descriptions. The stridulum morphology rarely examined described in taxonomy acoustics are only for six species, none which from Borneo. New specimens collected Borneo Belait Kuala Belalong Brunei Sandakan Sabah were initially identified as alienus and/or virescens based on traditional...

Spiky pygmy devils (Tetrigidae: Discotettiginae) are, because of the spiky pronotal projections and widened subapical antennal segments, among most unique grasshoppers in Southeast (SE) Asia. The taxonomy group was unclear past, so this study brings a taxonomic biographical review genus Discotettix Costa, 1864. New terminology is proposed for Scelimeninae. All valid species hitherto included are redescribed; new established shelfordi Hancock, 1907, Disconius Skejo, Pushkar et Tumbrinck gen....

The behavioural ecology of ultrasonic-singing katydids is not well understood, and the general bioacoustics, barely known for a few Neotropical Meconematinae, tends to be overlooked species from Southeast Asia. These include Asiatic Phlugidini, commonly as crystal predatory katydids. One its genera, Asiophlugis consists 16 which acoustic signals stridulum anatomy are broadly unknown. characters can used understand boundaries. Here, we sampled five sites in Malay Peninsula Borneo Island,...

Specimens representing three genera of Phaloriinae—Borneloria Gorochov, 2018, Phaloria (Papuloria) 1996 and Trellius (Zatrellius) 1999—were collected from Peninsular East Malaysia examined here. We report a new locality record for Borneloria moorei (Chopard, 1940) in Johor, Malaysia, the first this genus Malay Peninsula. From Sandakan, we discovered species describe here: puntung sp. nov. also recorded previously unknown calling songs tristis 2014 them
