Xyleborus metacuneolus Eggers, 1940: 150 View in CoL .
Xyleborus kaimochii Nobuchi, 1981: 143 View in CoL . Synonymy: Smith et al., 2018: 397.
Diagnosis: 2.40–2.50 mm long (mean = 2.46 mm; n = 5); 2.67–2.78 times as long as wide. This species is distinguished by elytral discal striae and interstriae clearly uniseriate punctate, anterior margin of pronotum with a row of serrations, and protibia obliquely triangular.
Material examined: Paratype Xyleborus metacuneolus , [ INDONESIA] : Java, Buitenzorg , 15.x.1923 ( NMNH, 1). [ INDONESIA] : Java, Boger [sic] viii.1964, N.L.H. Krauss ( NMNH, 4) . MALAYSIA: Sabah, Sipitang, Mendolong , 19.iv.1988, S. Adebratt ( RABC, 1) . PAPUA NEW GUINEA: Madang, Ohu, J. Hulcr, ex Gymnacranthera paniculata ( MSUC, 1) . SINGAPORE: Bukit Timah , 50m, 25‒27.x.1998, B. H. Jordal ( RABC, 2) .
Distribution: Brunei, Indonesia (Java, Sulawesi), Japan, East & West Malaysia, New Guinea, Philippines, Singapore, Sri Lanka, Taiwan, Thailand.
Host plants: Probably polyphagous. Recorded from Buchanania , Mangifera (Anacardiaceae) , Swietenia (Meliaceae) , Castanopsis (Fagaceae) ( Nobuchi 1981; Beaver & Liu 2010) and Gymnacranthera (Myrsticaceae) .
Remarks: The paratype from Indonesia (Java; NMNH) and two specimens from Singapore and Malaysia (Sabah; RABC) were all found to have different pronotal length/width ratios of 1.08, 1.23 and 0.88 respectively. It is unclear whether the species is morphologically variable or if this species may be a species complex. At the time of this study DNA data was only available for T. metacuneola s.s. Future research is necessary to determine species limits.
