Hamatoplectris spinifer

Adults reach a length of about 11–12 mm. They are dark brown, with the elytra dull and the pronotum slightly glossy. The clypeus is sparsely but evenly covered with short, erect setae, while the rest of the head and the pronotum are densely covered with somewhat erect, rather long, very strong setae, which are more densely packed on the lateral margin of the pronotum than on the disc. The elytra have considerably shorter setae, but of the same density. Only on the ribs, there are some longer spiny setae.^[3]
