Type species.

Xyleborus dimidiatus Eggers, 1927a: original designation.

Diagnosis.

Moderately sized, 2.4-3.3 mm, elongate, 2.54-2.89 × as long as wide, and shiny species. Stictodex is distinguished by the antennal club very broad, type 2, with segment 1 straight; declivity with first and second interstriae divergent, broadest at elytral summit; declivity flat and gradually sloped; scutellum flat, flush with elytra; protibiae inflated on posterior face; and procoxae contiguous.

Stictodex is similar to Arixyleborus with which it shares a broad antennal club but it lacks the distinctive elytral ridges and furrows.
