Thai distribution: C: Chanthaburi, Kanchanaburi, Sa Kaeo; N: Chiang Mai; S: Nakhon Sri Thammarat, Surat Thani, Trang ( Beaver 1999 as Leptoxyleborus concisus (Blandford)) .

New records: More than 150 specimens collected in all regions of the country except the North-East. One hundred specimens were collected in Malaise and pan traps in the Doi Chiang Dao NP in Chiang Mai by the participants in the Tiger project .

Other distribution: ‘Borneo’, India (Andaman Is., W. Bengal), Indonesia (Java, Maluku, Sumatra), Japan, Malaysia (E. & W.), Myanmar, New Guinea, Philippines. Intercepted in Japan and New Zealand in timber imported from the region. The species also occurs in Taiwan and Vietnam (R. A. Beaver, unpublished records). (4)

Biology: Polyphagous ( Browne 1961a). The species attacks large logs, small stems down to about 3 cm diameter, and lianes. The gallery system is irregularly branched, usually more or less in one transverse plane, and without brood chambers. Surface galleries may be present between the bark and wood in larger stems ( Beeson 1930, Browne 1961a). Beaver and Browne (1979) suggest that it may be attracted to sappy stems.
