Taxonomic history

Xyleborus nudibrevis Schedl, 1942a: 195.

Coptodryas nudibrevis (Schedl): Wood and Bright, 1992: 825.

Microperus nudibrevis (Schedl): Beaver et al., 2014: 55.


1.5−1.6 mm long (mean = 1.53 mm; n = 5); 2.5−2.91 times as long as wide. This species is distinguished by the elytral disc flat with short, steep obliquely truncate elytral declivity; posterolateral carina strong and denticulate; declivital interstriae straight from base to apex, never laterally broadened; declivital interstriae densely granulate, granules uniformly sized and spaced from declivital summit to elytral apex; declivital face opalescent, subshining.

Host plants

recorded from five genera in five different families of trees, and presumably polyphagous (Beaver et al. 2014)


Browne (1961a) suggests that the female lays eggs in clusters over a considerable period, the offspring from each cluster occupying a separate brood chamber.
