Cryptoxyleborus confusus Browne, 1950: 644.

Type material.

Holotype (NHMUK).

Diagnosis.

2.0 mm long (n = 1); 3.3 × as long as wide ( Sittichaya et al. 2019). This species is distinguished by its small size; elytral pit mycangia absent; antennal funicle 3-segmented; elytral interstriae reticulate-punctate, punctures confused and very densely placed at the base of the disc.

Similar species.

Cryptoxyleborus percuneolus , Fraudatrix simplex .

Distribution.

Brunei, Indonesia (Sumatra), East & West Malaysia, Thailand.

Host plants.

Only recorded from Shorea ( Dipterocarpaceae ) ( Browne 1961b; Beaver and Hulcr 2008).

Remarks.

Browne (1961b) notes that the gallery system differs from the usual pattern found in Cryptoxyleborus . In this species a surface brood chamber is excavated between bark and wood in which most of the larvae develop. However, there are also more deeply penetrating tunnels into the wood. Brood sizes ranged from 18-39 ( Browne 1961b).
