Cyclorhipidion pruinosum

75. Cyclorhipidion pruinosum (Blandford) *

Xyleborus pruinosus Blandford, 1896a: 214.

Cyclorhipidion pruinosum (Blandford): Wood & Bright, 1992: 701.

Thai distribution: S: Nakhon Sri Thammarat, Surat Thani. New to Thailand.

New records: Nakhon Sri Thammarat, Khao Luang NP, headquarters, 08° 22' 21.6'' N, 99° 44' 14.7'' E, 196 m, EtOH trap, various dates from 01.iii.2010 – 30.vi.2011 (W. Sittichaya) (71); Surat Thani, Khao Sok NP, EtOH trap, 22–24.iii.2006 (S. Stephens et al.) (1).

Other distribution: Indonesia (Sumatera), Malaysia (E. & W.), Philippines. Schedl (1942b as Xyleborus decipiens Eggers) recorded the species from Salomon I. in the Chagos Archipelago (now part of the British Indian Ocean Territory). The locality appears to have been uncritically changed to the Solomon Is. by subsequent authors (Browne 1961 a, Bigger 1988, Wood & Bright 1992). It remains to be shown whether the species actually occurs in the Solomon Is. Intercepted in Japan in timber from East Malaysia. (3)

Biology: Recorded largely from Canarium and other genera of Burseraceae, and clearly strongly attracted to this family, but also recorded from Balanocarpus and Dryobalanops (Dipterocarpaceae) and from Pithecellobium (Leguminosae) (Browne 1961a). The gallery system and brood development is described by Browne (1961a).
