Diagnosis

1.90−3.60 mm long; 2.15−2.52 times as long as wide. Leptoxyleborus can be distinguished by the elytral declivity extremely flat and broad, especially laterally; posterolateral declivital costa elevated, carinate, ending at interstriae 7; surface covered with scales or minute star-shaped scales; pronotum elongate, appearing conical from dorsal aspect; antennal club obliquely truncate, type 2, with segment 1 nearly covering the entire posterior face; submentum slightly impressed, shaped as a large triangle; protibia narrow, with fewer than 6 denticles; scutellum flat, flush with elytra; procoxae contiguous; mycangial tufts absent; and elytra unarmed.

Paleotropics and Oceania

Gallery system

Consists of a system of irregularly branched tunnels without brood chambers, lying more or less in one transverse plane. When the host tree has thick bark, transverse surface galleries may also be made between the bark and wood (Beeson 1930, Browne 1961b).
