Genus Camerunadora , new genus

Type species: Camerunadora bifasciata , new species (present designation)

Description. Elongate, subcylindrical, flattened above and below; surface punctate, setose. Head small, feebly produced between large eyes; eyes feebly diverging dorsad; frontovertex feebly longitudinally depressed between eyes; antennal cavities large, not widely separated; frontoclypeus emarginate; antennae short, serrate from antennamere 5. Pronotum wider than long, widest between posterolateral angles; anterior margin arcuate; posterior margin bisinuate on

either side of subtruncate median lobe; lateral margins angularly arcuate, from posterior margin gradually narrowing in posterior half, then strongly narrowing to anterobasal angles; disc convex medially, flattened laterally; scutellum wider than long, cordiform with anterior margin nearly straight; elytra wider than pronotum, widest across humeri, narrowing slightly above epipleura, then gradually narrowing to separately rounded, serrate apices; a portion of abdominal ventrite 1 visible from above with narrowed elytral lateral margins in middle portion of elytral length; prosternum with broad mentonniere, process wide and broadly, round-attenuate apically; abdominal ventrites with sutures arcuate; posterolateral angles of pleurites acute, slightly obliquely projecting and visible from above; ventrite 5 in female with apical transverse asperate-carinate declivous plate; legs with femora fusiform, pro- and mesofemora equal in length to respective tibiae, metafemur shorter than metatibiae; tibiae quadrate in crosssection, a single short arcuate spine distally; tarsi with tarsomeres 1–4 each slightly longer than preceding, with single ventral pulvillus; tarsomere 5 elongate, narrow, slightly longer than 1–4 together; claws bifid.

Etymology. The feminine generic name reflects both a geographical root for the country of origin and a connection to the Anadora Kerremans, 1898 , group of genera, my perception of the closest relationship among the Afrotropical Coraebina.

Comments. In the key to the Afrotropical Coraebini published earlier (Bellamy 1988), Camerunadora does not key to any single couplet. It shares several interesting character states not found in the same combinations with any other Afrotropical genera. With the single broadly produced mentonniere, the flattened pronotal disc, the lack of a large single costa on each elytron and the single carina between the antennal cavities, Camerunadora keys to the couplets of Planidia Kerremans, 1899 , Xenita Théry, 1941 and Paraxenita Bellamy, 1988 , yet differs from all three. As I noted above, the closest relationships appear to lie with the genera Anadora , Anaphlocteis Bellamy, 1986 and Chalcophlocteis Obenberger, 1924 .
