B744AA3D1B16FF917FBCF9234F1FD288.taxon	discussion	Remarks. The genus consists of nine species from India Subcontinent [Bolotettix anomalus (Hancock, 1910), Bolotettix inermis Hancock, 1915], Sumatra [Bolotettix affinis Günther, 1938, Bolotettix mentaweiensis Günther, 1938], Borneo [Bolotettix parvispinus Hancock, 1913, Bolotettix perminutus (Bolívar, 1887), Bolotettix planus Hancock, 1907, Bolotettix validispinus Hancock, 1907] and the Philippines [Bolotettix luzonicus Bey-Bienko, 1935, Bolotettix perminutus (Bolívar, 1887)] (Cigliano et al., 2025).	en	Tan, Ming Kai, Muhammad, Amira Aqilah, Damit, Dayang Fazrinah Binti Awg, Japir, Razy, Chung, Arthur Y.

Holotype: EAST MALAYSIA • ♂; Sabah State; Sinipung Hill, near Long Pasia; N 4.44622 E 115.71439, 1563.0 ± 13.0 m. a. s. l.; 21 November 2024, 19 h 32; on foliage of herb near mossy rotten log; coll.

Paratypes: EAST MALAYSIA, Sabah State; Sinipung Hill, near Long Pasia • 1 ♂; same details as holotype; SBH. 24.195 (MNHN) • 2 ♂; N 4.44669 E 115.71443, 1598.0 ± 11.5 m. a. s. l.; 21 November 2024, 20 h 25; on branch near dead log; coll. M. K. Tan; SBH. 24.199, 200 (ZRC). Generic status. We tentatively place the new species under Bolotettix Hancock, 1907 despite the similarities with species from the genus Zhengitettix Liang, 1994. Bolotettix is a little-known genus, and the species are in need for taxonomic revision. However, the new species shows similarities with the type species Bolotettix validispinus Hancock, 1907 (see diagnosis). On the other hand, Zhengitettix has not been recorded in Borneo, even though its distribution ranges from Philippines to Indochina.	en	Tan, Ming Kai, Muhammad, Amira Aqilah, Damit, Dayang Fazrinah Binti Awg, Japir, Razy, Chung, Arthur Y.

B744AA3D1B15FF957FBCFF7D4E59D62C.taxon	diagnosis	Diagnosis. The new species is characterised by its small size (BL = 6.59 ± 0.15 mm; PL = 7.86 ± 0.23 mm) and marmorated colour patterns, its facial carinae (COS) wide, its pronotal disc with the prozonal carina (CA) and interhumeral carina (CD) thick and strongly raised; the spine of its lateral lobe acute triangular but slightly curved posteriorly and not elongated; EW / VW = 1.4 ± 0.04; PL / PW = 2.36 ± 0.05; HFL / HTL = 1.20 ± 0.04. From type species Bolotettix validispinus Hancock, 1907 (Fig. 4 B) from Borneo, the new species differs by its face less slender, its facial carinae (COS) thicker and more widely spaced apart (SW / VW = 0.65 vs. 0.53); EW / VW = 1.46 (vs. 2.00); the prozonal carina (CA) and interhumeral carina (CD) thick and strongly raised, not different from the median carina (as compared to thinner, less distinctly raised compared to its median carina); the spine of its lateral lobe less slender and acute and curved slightly posteriorly; its pronotum slightly shorter (PL / PW = 2.36 vs. 2.44); its colour patterns generally more marmorated (including pronotum and legs). From Bolotettix parvispinus Hancock, 1913 (Fig. 4 C) from Borneo, the new species differs by the eyes in lateral view more globular; its face less slender, its facial carinae (COS) thicker and more widely spaced apart (SW / VW = 0.65 vs. 0.34); the prozonal carina (CA) and interhumeral carina (CD) thick and strongly raised, not different from the median carina (as compared to thinner, less distinctly raised compared to its median carina); the spine of its lateral lobe less slender and acute; its lateral lobe with the ventral sinus acute and distinctly narrower in angle than the tegminal sinus (obtuse) (instead of being nearly identical); its colour patterns (including pronotum and legs) generally more marmorated.	en	Tan, Ming Kai, Muhammad, Amira Aqilah, Damit, Dayang Fazrinah Binti Awg, Japir, Razy, Chung, Arthur Y.

B744AA3D1B1EFF9B7FBCFAF54948D222.taxon	discussion	Remarks. We observed two colour forms of this species: the darker and lighter form. While the darker form is generally dark grey, including head, pronotum and legs, the lighter form differs by the head and pronotal disc orange brown (its pronotum disc at the apex mottled with some black parts) and the legs generally with more pale rings. The syntypes appear to be of a darker form. However, the lighter form appears to be more commonly seen. In Meligan (SBH. 24.239 – 2247), both dark and light forms were found co-occurring on the same tree trunk (Fig. 7).	en	Tan, Ming Kai, Muhammad, Amira Aqilah, Damit, Dayang Fazrinah Binti Awg, Japir, Razy, Chung, Arthur Y.

B744AA3D1B1AFF9D7FBCFE784D94D60A.taxon	discussion	Remarks. The species was first described from Kalimantan. The material from Maliau Basin and Tabin Wildlife Reserve represents the first record of this species in Sabah. Our specimens resemble the syntypes in the general habitus, but differ slightly in the relative size of the anterior and posterior lateral processes of the pronotal lateral lobe and the carinae on the anterior femora.	en	Tan, Ming Kai, Muhammad, Amira Aqilah, Damit, Dayang Fazrinah Binti Awg, Japir, Razy, Chung, Arthur Y.
