Ips longifolia (Stebbing)

Tomicus longifolia Stebbing, 1909: 26 .

Ips longifolia (Stebbing): Hagedorn 1910: 56.

Recorded from Bhutan by Schmutzenhofer (1988a) and Cognato & Sperling (2000).

Distribution. Bhutan, India (Himachal Pradesh, Uttar Pradesh), Pakistan.

Biology. The species primarily attacks Pinus roxburghii (Pinaceae) in the subtropical conifer forest belt of the Himalayas at elevations between 500 and 2000 m (Kirisits et al. 2002). Other conifers may also be attacked, but confusion with closely-related species of Ips makes most early host records unreliable. It is considered to be a secondary species, attacking severely stressed or dying trees (Kirisits et al. 2002).
