Taxonomic history

Xyleborus suturalis Eggers, 1930: 200.

Cnestus suturalis (Eggers): Wood and Bright, 1992: 803.

Diagnosis

2.8 mm long (mean = 2.8 mm; n = 2); 2.55 times as long as wide. This species can be distinguished by the presence of a mesonotal mycangial tuft on the pronotal base, rounded elytral declivity, elytra often with a transparent area, pronotum from dorsal view type 1, antennal club type 1, with no sutures visible on the posterior face, three segmented antennal funicle, protibia obliquely triangular, declivital striae with punctures much coarser, deeper than those of disc, interstriae 2 and 3 strongly narrowed toward apex, striae 1−3 impressed.

This species strongly resembles Cnestus aterrimus which has declivitial strial punctures similarly sized to those of disc, interstriae 2 and 3 not narrowed toward apex, and at most striae 1 and 2 impressed.
