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 data on some crickets of the subfamilies Landrevinae, Phaloriinae and Podoscirtinae (Orthoptera: Grylloidea) from Laguna (Philippines: Luzon Island).

Recent orthopteran sampling at Laguna in Luzon Island of the Philippines revealed noteworthy crickets from the subfamilies Landrevinae, Phaloriinae and Podoscirtinae. We describe one species new to science from the subfamily Podoscirtinae: Mnesibulus laguna n. sp.

Taxonomic study of Lebinthus Stål, 1877 (Orthoptera: Gryllidae: Eneopterinae) with description of six new species in the Philippines.

The genus Lebinthus Stål, 1877 (Orthoptera: Gryllidae: Eneopterinae: Lebinthini) in the Philippines is studied. New locality records are provided for L. bitaeniatus Stål, L.

Taxonomy and bioacoustics of Meconematinae (Orthoptera: Tettigoniidae) from Laguna (Philippines: Luzon).

Katydids from the subfamily Meconematinae sing at ultrasonic frequencies. Owing that many of them are nocturnal, elusive and low in abundance (since they are predatory), there is a dearth of information on these katydids and their bioacoustics, especially for species in the understudied yet mega-diverse Southeast Asia. Recent orthopteran surveys in Laguna, Luzon Island in the Philippines led to the discovery of two interesting Meconematinae katydids.

An account on the Orthoptera from Siargao Island (Southeast Asia: Philippines: Mindanao).

Siargao Island is located on the southeastern part of the Philippines. We have very little knowledge on the Orthoptera from this island which is covered with forest over limestone, open vegetation, and mangrove, despite being designated as one of the terrestrial Key Biodiversity Areas (KBAs) in the Philippines. We conducted surveys in 2018 to search for orthopterans.

Taxonomic notes on Trigonidium and related groups with one new species from the Philippines (Orthoptera: Trigonidiidae; Trigonidiinae).

The taxonomy of Old World Trigonidiinae (sword-tailed crickets) is in need of major revision. This includes its type genus Trigonidium. Various authors have different opinions on what constitutes the subgenera and species of Trigonidium s.

New species of Ornebius (Orthoptera: Mogoplistidae; Mogoplistinae) from Siargao Island of the Philippines.

Two new species of Ornebius are described from Siargao Island, Mindanao of the Philippines: O. alvarezi sp. nov.

Taxonomic review of the genus Paranisitra Chopard (Orthoptera: Gryllidae: Eneopterinae: Nisitrini) with description of a new species from Mindanao.

The genus Paranisitra Chopard (Orthoptera: Gryllidae: Eneopterinae: Nisitrini) is reviewed. New records and additional descriptions are provided for P. longipes Chopard, P.

A new species of Landrevinae (Orthoptera) from the Philippines, with notes on Endodrelanva and Endolandrevus (Orthoptera: Gryllidae; Gryllinae; Landrevini).

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.

New taxa and notes on spine-headed katydids (Orthoptera: Conocephalinae: Agraeciini) from the Philippines.

The diversity of the Agraeciini spine-headed katydids (Orthoptera: Tettigonioidea: Conocephalinae) in Southeast Asia remains poorly known, with species still awaiting discovery. Recent field collections in the Philippines resulted in the discovery of three novel species and redescription of two known species of Agraeciini, namely, (1) Anthracites furvuseques sp. nov.
