AB  - We are describing a rhabdom organization of the eye of the chrysanthemum beetle <i>Phytoecia rufiventris</i> that to date has not been described from any other insect. In cerambycid beetles free rhabdomeres, forming a circular, open rhabdom, surround a central rhabdom made up of the rhabdomeres of one or two cells. In <i>Phytoecia rufiventris</i> the central rhabdomeres are missing throughout the eye and the microvilli of the outer 6 rhabdomeres are regularly oriented in three directions. Following the classification of rhabdom types suggested by Wachmann (1979), we suggest to name the rhabdom arrangement seen in the retina of <i>Phytoecia rufiventris</i> “Grundmuster 3”. This pattern ought to facilitate polarization sensitivity and movement perception, features that agree with the behavioural repertoire of <i>Phytoecia rufiventris</i>.
