==Description==
The body length of ''Dermatoxenus'' ranges from 8.0 to 13.0 mm.<ref name = anderson>{{cite journal |last1=S. Anderson |first1=Robert |title=The genus Dermatoxenus Marshall 1916 (Coleoptera: Curculionidae: Entiminae: Dermatodini) in the Philippines |journal=Journal of Tropical Coleopterology |date=28 June 2021 |volume=2 |pages=26-34}}</ref> The head is transversely impressed behind the eyes, and the [[frons]] bears a median furrow between the eyes. The eyes are small, rounded, and prominent. The [[Rostrum (anatomy) |rostrum]] has a crosswise groove at the base, just in front of the eyes, and a deep central furrow with one or two shallower grooves on each side. The [[epistome]] is large and bare. The scrobe (or specialized antennal groove) is short and bends sharply downward, ending some distance before the front edge of the eye. <ref name = anderson />

The [[Antenna (zoology)|antenna]] have a short basal segment that does not reach the anterior margin of the eye. The first two segments of the funicle are longer than the ones that follow. The mandibles have a very small scar, and the deciduous process is stalked.<ref name = anderson />

The pronotum is approximately as long as it is wide, widest at or near the base, and sometimes has a shallow middle groove. The rear margin is slightly extended at the center. The small scutellar shield is not visible from above. The elytra are broader at the base than the pronotum and appear swollen toward the back when viewed from the side. The shoulders are distinct. The elytral intervals may be slightly raised or tuberculate, and there are ten complete rows of punctures (striae), which may be either clear or faint.<ref name = anderson />

The legs have clavate femora without ventral teeth. The metatibia is straight, with a small, rounded inner apical spur that is largely concealed by setae or scales. The corbel bevel is broad, closed, and densely scaled. The third tarsal article is large, deeply bilobed, and densely pilose ventrally; the claws are connate.<ref name = anderson />

The aedeagus is slender, with very long aedeagal apodemes about twice the length of the aedeagal body. The endophallus contains a very long, semi-rigid, rod-like flagellum that exceeds the length of the apodemes, based on three species examined.<ref name = anderson />
