Some questions of classification of the subfamily Landrevinae Saussure, 1878 are discussed: the tribe Odontogryllini Mello, 1992, trib. resurr. is restored from synonymy; the genera Oreolandreva Chopard, 1945, Microlandreva Chopard, 1958 and Creolandreva Hugel, 2009 are included in the tribe Prolandrevini Gorochov, 2005. Some genera of the tribe Landrevini are considered: Duolandrevus Kirby, 1906; Repapa Otte, 1988; Endolandrevus Saussure, 1877; Endodrelanva Gorochov, 2000; Kotama Otte, 1988; Odontogryllodes Chopard, 1969. New taxa (38) from Indonesia, Malaysia, Vietnam, Laos, Philippines, Madagascar and Reunion Island are described: D. (Duolandrevus) bengkulu sp. nov., D. (D.) curup sp. nov., D. (D.) selatan sp. nov., D. (D.) manna sp. nov., D. (D.) lampung sp. nov., D. (D.) kubah sp. nov., D. (D.) sympatricus sp. nov., D. (D.) kalimantan sp. nov., D. (D.) balikpapan sp. nov., D.

(Landrevini); Striduleva gen. nov., Astriduleva analamazaotra gen. et sp. nov. (Prolandrevini). Neotype for D. (D.) coulonianus (Saussure, 1877) is designated; D. (D.) sulawesi Gorochov, 2000, comb. nov. and D. (E.) paradoxus Gorochov, 2001, comb. nov. are transferred from the genus Repapa Otte, 1988 to Duolandrevus s. l. (to its subgenera Duolandrevus s. str. and Eulandrevus, respectively); the former species R. proxima Gorochov, 2004 is considered as a subspecies of the latter species, i. e. as D. (E.) paradoxus proximus stat. nov.; subgeneric position of some old species of Duolandrevus s. l. is established or changed; data on previously unknown females and new localities are also given. Обсуждены некоторые вопросы классификации подсемейства Landrevinae Saussure, 1878: триба Odontogryllini Mello, 1992, trib. resurr. восстановлена из синонимии; роды Oreolandreva Chopard, 1945, Microlandreva Chopard, 1958 и Creolandreva Hugel, 2009 по- мещены в трибу Prolandrevini Chorochov, 2005. Рассмотрены некоторые роды трибы Landrevini: Duolandrevus Kirby, 1906; Repapa Otte, 1988; Endolandrevus Saussure, 1877; Endodrelanva Gorochov, 2000; Kotama Otte, 1988; Odontogryllodes Chopard, 1969.
