Imperious Sawyers

Cerambycidae, Prioninae, Callipogonini,


The six species comprising this genus are widely distributed, wholly Neotropical cer-ambycids, impressive for their rich amber or chestnut-colored elytra and great size (BL of most 10—11 cm). One species, Callipogon armillatum (fig. 9.13d) is very large, almost as long (BL to 15 cm) as the titanic longhorn.

They are all fairly elongate, often have strong spines on the margins of the pro-thorax, and the forelegs are slightly longer than the other legs. Also, they have small but heavy incurved or upturned jaws. In major males of several species, the mandibles are grossly enlarged. Those of C. barbatum (fig. 9.13c) and C. senex are massive, forked structures bearing a dense vestiture of reddish-brown hairs on their inner surfaces. The elytra in these are variable, solid brown or with conspicuous, broad, longitudinal streaks of white pubescence.

The larvae bore into the heartwood of pines in Central America and a wide variety of hardwoods in all areas. They are considered serious timber pests.
