(Tettigonioidea, Tettigoniidae , Pseudophyllinae )

Material examined. 1 female (B7.19), Ranau Kampong Nalumad [= Kampong Nalumad, Ranau], 1 November 1999, coll. Postar Miun, det. M. Muzamil (2010) as Onomarchus cretaceus ( Serville, 1838) [det. M. K. Tan] ( OSF Specimen ID = 147047) ; 1 male (B7.19), Beluran, 25 June 1992, coll. FRC staff, det. M. Muzamil (2010) as Onomarchus cretaceus ( Serville, 1838) [det. M. K. Tan] ( OSF Specimen ID = 147048) ( Figs. 32 , 33 ) ; 1 female (B7.19), Sepilok, Sandakan, 8 March 1977, coll. Titi, det. M. Muzamil (2010) as Onomarchus leuconotus ( Serville, 1838) [det. M. K. Tan] ( OSF Specimen ID = 147050) ( Fig. 34 ) ; 1 male (B7.19), Ulu Dusan, Sandakan, 8 February 1977, coll. L. Madani, det. M. Muzamil (2010) as Onomarchus leuconotus ( Serville, 1838) [det. M. K. Tan] ( OSF Specimen ID = 147049) ( Fig. 34 ) ; 1 female (B7.19), Sepilok Mile 14, 9 November 1977, coll. Jakar, det. M. Muzamil (2010) ( OSF Specimen ID = 147051) ( Fig. 35 ) .

Remarks. Characters used to differentiate these species by Serville (1838) and De Jong (1939) are not particularly useful. Tentatively, we considered all of them as O. uninotatus by the wing venation, meta- and meso-sterna and hind tibial dorsal thorns (although all these characters show some variations). Size can also vary between specimens and we recommend further investigation into this complex species.
