161. Indocryphalus intermedius (Sampson) *

Xyloterus intermedius Sampson, 1913: 445 .

Indocryphalus intermedius (Sampson) : Browne, 1970: 562.

Thai distribution: N: Chiang Mai. New to Thailand.

New records: Chiang Mai, Doi Inthanon NP, checkpoint 2, 18° 31.559' N, 98° 29.941' E, 1700 m, MT, various dates from 29.vi–13.ix.2006 (Y. Areeluck) (9) .

Other distribution: Bhutan, India (Himachal Pradesh, W. Bengal), Myanmar, Nepal. (2)

Biology: Recorded from four different families and probably polyphagous ( Beaver 2000). The gallery system resembles that of Scolytoplatypus (see above) with simply branched tunnels in one transverse plane. The eggs are laid in niches, and the larvae develop in separate cradles arranged in series above and below the main gallery ( Schedl 1951, Beeson 1961).

Doubtful records

We consider the following published records are doubtful and require confirmation.

Xyleborus canus Niisima ( Hutacharern et al. 2007) . This species is otherwise recorded only from Japan, and is apparently known only from the holotype ( Niisima 1909).

Xyleborus torquatus Eichhoff ( Schedl 1962a) . This species is considered to be a synonym of Xyleborus volvulus (F.) ( Wood & Bright 1992), a species which is largely neotropical. It seems likely that the single specimen determined by Schedl (1962) is actually a specimen of the closely similar species, Xyleborus perforans (Wollaston) (see above).
