Type material.

Holotype Xyleborus depressus (NHMW).

New records.

China: Jiangxi, Long Nan, 12.vii.2016, Lv-Jia, Lai, S-C., ex Cyclobalanopsis glauca (RABC, 1). Japan: Kagoshima Pref., Tarumizu Oonohara broadleaf forest, 425 m, 1.viii.2000, Y. Sato, ex EtOH baited trap (RJRC, 1); as previous except: 27.viii.2000 (RJRC, 1).

Diagnosis.

1.9-2.1 mm long (mean = 1.99 mm; n = 5); 2.22-2.53 × as long as wide. The species is readily distinguished by its small size and declivital interstriae bearing uniseriate short, semi-erect scales; and posterolateral declivital margin costate.

Similar species.

Ancipitis puer , Leptoxyleborus sordicauda .

Distribution.

China* (Jiangxi), Indonesia (Sumatra), Japan*, East & West Malaysia, Solomon Islands, Thailand.

Host plants.

Polyphagous ( Browne 1961b; Ohno 1990; Ohno et al. 1988).

Remarks.

This species bears striking morphological similarity to Ancipitis species. Upon close examination of specimens we determined that this species should be moved to Leptoxyleborus because of the following combination of characters: antennal club truncate, type 2, with segment 1 nearly covering the entire posterior face; segment 1 of the antennal club shorter than pedicel; scape regularly thick; protibiae obliquely truncate; elytral interstriae seriate and bearing scales; and declivital face flat.
