Previous genus: Xyleborus Diagnosis: The species differs from other Diuncus spp. in that each interstria 2 to 5 bears one conical tooth (4 on each elytron) on top of elytral declivity, creating an array of teeth, four on each elytron (in most other Diuncus only interstriae 2 and 3 usually bear denticles). Discussion. The species bears all characters identifying it as Diuncus : the antennae are of type 1, very flat; the pronotum is rounded, short, with two prominent serrations on the anterior edge; very slender protibiae; no signs of mesonotal or elytral mycangium, and the declivity is broadened posteriad and surrounded with elevated carina. Previously synonymized species: Xyleborus clerodendronae alpinus Schedl , Xyleborus clerodendronae morosus Schedl Biology: One of only two Diuncus from Africa. Examined material: Nigeria , Kamatan, ( BMNH ).
