New species of Itara (Orthoptera: Grylloidea: Itarinae) and descriptions of calling songs from Mindanao and Sabah.

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

Taxonomy and bioacoustics of little-known Grylloidea crickets (Orthoptera, Ensifera) from Mindanao, Philippines.

Orthopteran surveys were conducted recently on Mindanao Island of the Philippines. Four species new to science are described here: Mistshenkoana lunotan sp. nov., Mistshenkoana higaonon sp. nov. and Ectatoderus dubius sp. nov. from Misamis Oriental; and Phaloria (Phaloria) rotundata sp. nov. from Agusan del Sur. Based on new collected material, Madasumma fuscoirrorata Chopard, 1925, first described based on a single female from Mindanao, is transferred to Varitrella (Cantotrella) fuscoirrorata (Chopard, 1925) comb. nov. We also describe the male of this species for the first time. Madasumma zamboanga Otte, 2007, first described from Zamboanga del Norte (Mindanao), is also transferred to Mnesibulus (Amnesibulus) and redescribed: Mnesibulus (Amnesibulus) zamboanga (Otte, 2007) comb. nov. We also describe previously unknown calling songs of seven species: Falcerminthus parvus (Baroga-Barbecho & Robillard, 2020), Ajorama balatukanis Otte, 1988, Varitrella (Cantotrella) bakeri (Chopard, 1925), Varitrella (Cantotrella) fuscoirrorata (Chopard, 1925) comb. nov., Phaloria (Phaloria) rotundata sp. nov., Ornebius bioculatus Tan et al., 2019 and Ectatoderus dubius sp. nov.
