Type material.

Lectotype (NHMW).

Diagnosis.

1.4 mm long (n = 1); 2.55 × as long as wide (Sittichaya et al. 2019). This species is distinguished by its minute size; elytral pit mycangia absent; antennal funicle 3-segmented; elytral interstriae distinctly seriate punctate, without very densely placed punctures at the base.

Similar species.

Cryptoxyleborus confusus, Fraudatrix simplex .

Distribution.

Indonesia (Java), East Malaysia, Thailand.

Host plants.

No host records are known but hosts are presumably similar to other Cryptoxyleborus which are specific to Dipterocarpaceae (Beaver and Hulcr 2008).

Remarks.

One gallery system investigated consisted of an unbranched entrance tunnel leading to a single terminal brood chamber enlarged in the longitudinal plane, with multiple tunnels extending further into the wood (Beaver and Hulcr 2008).
