Cossyphodes andraei

Diagnosis
C. andreaei n.sp. can be recognised by lacking secondary elytral keels in combination with a rudimentary inner main keel present only in the anterior quarter of elytra (Fig. 7), and by eyes with two rows of ocelli. C. machadoi Basilewsky, 1952, from Angola is similar, but the inner elytral keel is complete and the eyes narrower with only one row of ocelli.

Body dark brown without colour pattern, eyes darker. Body length 2.5–2.6 mm. Head semicircular, clypeus not separated, clypeal lines indistinct, straight; anterior and lateral margins somewhat bent upwards, frons without impression or tubercles; head surface with regular microgranulation; eyes sickle-shaped, composed by two rows of large, dark ocelli, each row with about five ocelli; antennae 11-segmented with two large apical antennomeres forming club, as usual for the genus. Pronotum 2.2 times broader than median length, posterior corner rectangular, acute, anterior corner rounded; all margins unbordered; surface with same microgranulation and microsetation as on head, disc on each side with three fine longitudinal keels, internal keel sometimes shortened anteriorly, additionally with traces of a medial keel, for direction, distances of these keels, see Fig. 7; prosternal process elongate triangular with protruding acute posterior angle. Elytra widest shortly before base, 1.2 times longer than broad; elytra with four primary keels and without any secondary keels, internal main keel present only in anterior quarter of elytra, for direction, distances of these keels, see Fig. 7; surface with the same microgranulation and microsetation as on head and pronotum.
