Type material.
Syntypes Xyleborus amphicranoides (SDEI, 2). Lectotype Xyleborus a. latecavatus (NMNH).
New records.
China: S Yunnan, Xishuangbanna, 20 km NW Jinghong, vic. Man Dian (NNNR), 22°07.80'N, 100°40.05'E, 730 m, forest, 6.vi.2008, A. Weigel (RABC, 1). Vietnam: Ninh Binh, Cuc Phuong N.P., 7.iii.2018, 20.34932, 105.59669, 431 m, A.I. Cognato, S.M. Smith, VN 130, ex 8 cm diameter bole (MSUC, 1).
Diagnosis.
3.3-5.4 mm long (mean = 4.26 mm; n = 9); 3.23-3.6 × as long as wide. This species is distinguished by the posterolateral extensions of elytra long, as long as width of apical emargination; apex of posterolateral extensions with a denticle; declivity strongly excavated; and large size.
Similar species.
Distribution.
China* (Yunnan), Indonesia (Java, Mentawai Is, Sumatra, Sulawesi), Laos, East & West Malaysia, Philippines, Thailand, Vietnam*.
Host plants.
Polyphagous ( Browne 1961b; Ohno 1990).
Remarks.
Xyleborus amphicranoides parvior has been considered to be a synonym of D. amphicranoides . As noted by Browne (1981b) in his description, the species is morphologically identical to D. amphicranoides but smaller in size, 3.2-3.4 mm long ( Browne 1981b). Additional specimens from China and Thailand (RABC) measure 3.3-3.8 mm (mean = 3.55, n = 2), 3.39-3.4 × as long as wide. Typical Debus amphicranoides are larger, 4.8-5.4 mm long (mean = 4.97 mm; n = 5); 3.23-3.6 × as long as wide. The species are not diagnosable from each other except in body length. It is possible that they are different species but further investigation with DNA sequence data will be necessary to resolve species limits.
