Comparisons between the genera Olivensa Lane, 1965 and CeDhalodina Bates, 1881 are provided. Cephalodina crassiceps Bates, 1881, is designated the type species and a key to the species of Cephalodina is presented. Cephalodina acangassu, sp. n. , is described from Ecuador.

Both genera share the follQwing common char­ acters: elytral humeral carma absent; internal side 2 ofbasal flagellomera with sparseshort hairs; upper ocular lobes distant; head developed, wide, globose (especially in females). Cephalodina can be distin· guished from Olivensaby bicoloured antennae, with black and white segments, humerus not projected, and basal lateral declivity of elytra regularly con· vex. Besides, in Cephalodina, the vertex is pubes­ cent, opaque and the prothoracicai pubescence is 3 white and dense (except on a circular black area in the middle of the pronotum (fig. 3».
