Taxonomy

Truncaudum Hulcr and Cognato, 2010a: 24.

Diagnosis

Small to moderately sized, somewhat elongate (1.90−2.90 mm long, 2.44−2.90 times as long as wide), and densely pubescent. The genus is recognized by the declivity obliquely or abruptly truncatepronotum elongate without distinct serrations on anterior margin; scutellum visible; procoxae contiguous; and mycangial tufts absent. The two species in Southeast Asia are strikingly similar to several small Cyclorhipidion species and can be distinguished by the type 2 antennal club (Cyclorhipidion has types 3, 4, 5).
