New species, locality records and calling songs of crickets of the subfamily Phaloriinae (Orthoptera: Grylloidea: Phalangopsidae) from Malaysia.

Specimens representing three genera of Phaloriinae-Borneloria Gorochov, 2018, Phaloria (Papuloria) Gorochov, 1996 and Trellius (Zatrellius) Gorochov, 1999-were collected from Peninsular and East Malaysia and examined here.

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.

Notes on the Eneopterinae (Orthoptera, Grylloidea, Gryllidae) from eastern Sabah.

Based on material collected during recent fieldwork in eastern Sabah, the males of Nisitrus danum Robillard & Tan and Cardiodactylus variegatus Gorochov & Robillard are described for the first time, along with their calling songs. New locality records of N. danum, N.

Taxonomy and bioacoustics of some katydids of the tribes Meconematini and Phisidini (Orthoptera, Tettigoniidae, Meconematinae) from eastern Sabah.

A new species of Meconematini is described from Tabin Wildlife Reserve in eastern Sabah: Cercoteratura repens sp. nov. This is the first report of the genus Cercoteratura in Sabah.

Taxonomy and bioacoustics of scaly crickets (Orthoptera, Mogoplistidae, Mogoplistinae) from Borneo and Singapore.

A species of scaly cricket is described here: Ornebius lupus sp. nov. from the mangrove forests in Singapore.

New taxa and notes on bark and bush crickets (Orthoptera, Grylloidea, Gryllidae, Landrevinae and Podoscirtinae) from Sabah.

From the eastern parts of Sabah, four new species of crickets are described, two of which are from the subfamily Landrevinae and two from the subfamily Podoscirtinae: Duolandrevus (Duolandrevus) nobilis sp. nov. and Odontogryllodes spinifer sp.

A review of the genus Monseremus Ingrisch, 2018 (Orthoptera, Stenopelmatoidea, Gryllacrididae) from Borneo.

We review the taxonomy of the gryllacridids from a small genus Monseremus Ingrisch, 2018. Monseremus bellus (Tan Wahab, 2018) comb. nov.

Contribution to the taxonomy of Uvarovia (Orthoptera: Chorotypidae: Mnesicleinae) from Borneo and Malay Peninsula.

Mnesicleinae is a little-known subfamily of Chorotypidae and consists of 19 genera distributed throughout the Malay Archipelago, including Uvarovia Bolvar, 1930. For many species from this subfamily, nearly nothing is known after their original descriptions. Based on new materials from recent surveys, we were able to examine specimens from two species: Uvarovia longipennis Bolvar, 1930 from Malay Peninsula (also type species for genus) and Uvarovia gracilipes Bolvar, 1931 from Borneo.

New species and taxonomic notes of scaly crickets (Orthoptera: Mogoplistidae: Mogoplistinae) from Borneo.

Recent orthopteran surveys in the hyper-diverse Borneo, i.e., Brunei Darussalam and Sandakan in Sabah, allow us to review the scaly crickets from the subfamily Mogoplistinae there.

A taxonomic study on the Bornean and Philippines Sword-tailed Crickets in the genus Rhicnogryllus Chopard, 1925 (Orthoptera: Trgonidiidae; Trigonidiinae).

Rhicnogryllus Chopard, 1925 is a small and relatively unknown group of Sword-tailed Cricket of the subfamily Trigonidiinae. This genus currently comprises 12 species from Asia, Africa (including Madagascar), South America and the Pacific. Species have been recognised by the presence of parallel and elevated veins in both males (which lack stridulatory organs) and females.

New taxa of crickets (Orthoptera: Grylloidea: Phaloriinae, Phalangopsinae, Itarinae and Podoscirtinae) from Borneo (Brunei Darussalam and Sandakan).

Uncovering the Grylloidea and Tettigonioidea (Orthoptera: Ensifera) in the Forest Research Center (Sepilok) Entomological Collection.

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 and digitization of collections by numerous museums, have helped to make images and information about the type specimens available on the World Wide Web. However, many local collections, especially those from the poorly studied regions of Southeast Asia, are still not available to the public.

New taxa of crickets (Orthoptera: Grylloidea: Gryllinae, Phaloriinae and Pteroplistinae) from northern Borneo (Belait and Sandakan).

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 Tan, Gorochov Wahab, sp.

Crickets of the subfamily Eneopterinae (Orthoptera: Grylloidea) from Sandakan, Sabah: one new species and calling songs of a sympatric species.

Orthoptera from Sandakan, Sabah are relatively understudied compared to some other parts of Borneo, and lack of information of species there can impede our understanding of the origins and biodiversity of orthopterans in Borneo and, in general, Southeast Asia. Based on a recent orthopteran survey in Sandakan, one new species of Lebinthus Stål is described: Lebinthus sandakan sp. nov.
