Sympaestria acutelobata Brunner von Wattenwyl, 1878: 185 — Dohrn, 1892: 73; Kirby, 1906: 432; Karny, 1923: 157; Karny, 1926a: 110; Karny, 1926b: 150; Karny, 1926c: 274; Tan, 2014b: 588; Kang, Liu & Liu, 2014: 317; Tan, Japir & Chung, 2019: 326

Material examined. EAST MALAYSIA: Sabah State • 2♂; Mount Trus Madi, Trusmadi Entomology Camp; N5.44174, E116.45074, 1189.0± 5.2 m.a.s.l.; 31 October 2023, 19h58–20h23; attracted to light trap at ridge; coll. M.K. Tan, J.L. Yukang & A.Y.C. Chung; SBH.23.20, 21 (FRC) • 1♂; Mount Trus Madi, Trusmadi Entomology Camp; N5.44307, E116.45155, 1192.0± 5.6 m.a.s.l.; 31 October 2023, 20h33–20h49; attracted to light trap near camp; coll. M.K. Tan, J.L. Yukang & A.Y.C. Chung; SBH.23.44 (FRC)

Remarks. This species can be recognised by the shape of the male tenth abdominal tergite having a short and sharp tooth, smaller size, longer male subgenital plate with deeper and narrow emargination and longer male styli; and the presence of red ventral carinae on hind femur.

Sympaestria lampra Hebard, 1922 reported by Tan & Wahab (2018b) superficially resembles Sympaestria acutelobata more.

Ecology. As reported in Tan & Wahab (2018b), this genus is more readily encountered at light trap rather than opportunistic sampling, suggesting that these katydids are probably canopy species.

Distribution. Borneo, Java, Malay Peninsula and Thai-Peninsula and Sumatra

Type locality. Borneo
