New and little known taxa of the genera Ancylecha Serville, 1838 and Leptoderes Serville, 1838 (Orthoptera: Tettigoniidae: Phaneropterinae) from the Indo-Malayan Region

A new material on the Indo-Malayan genera Ancylecha Serville, 1838 and Leptoderes Serville, 1838 from the tribe Holochlorini is reviewed. The following new species and subspecies are described: Ancylecha exotica sp. n. and A. fenestrata longicarinata subsp. n. from northern part of Borneo, Leptoderes shuzhenae laosi subsp. n. from northern half of Laos, L. vietnami sp. n. from southern half of Vietnam. Also Ancylecha fenestrata fenestrata (Fabricius, 1793) and Leptoderes ornatipennis Serville, 1838 are briefly redescribed, but determination of the nominotypical subspecies of A. fenestrata is somewhat problematic and requests additional data.
