Andersson, A. 1980. The fine structure of a sensory organ of a cladocop ostracode (Crustacea) belonging to the organ of Bellonci (sensory pore) complex. (Department of Zoology, University of Lund, Sweden.) — Acta zool. (Stockh.) 61(1): 51–58. The organ of Bellonci, a complex of cephalic receptors, has previously been reported from two ostracode groups. On morphologic grounds, a cephalic receptor of a third ostracode group (Cladocopa) is believed to be an organ of Bellonci. The organ is situated on the forehead above the first pair of antennae and consists of two feathered hairs. Two nerves, each formed by one dendrite, run from the protocerebrum into the hairs where they terminate with ramose cilia. The dendrites, as well as the cilia and ciliary branches, are enveloped by glial cells. Distally, these cells form cavities around the ciliary branches. The ciliated neuronal connection and the glial cavities, together with other morphologic characteristics of the organ, support a homologization with the organ of Bellonci of other myodocopid ostracodes.
