Correspondence of dorsal and ventral parts in millipedes Diplopoda The summary of a free discussion

, : Correspondence of dorsal and ventral parts in millipedes Diplopoda The summary of a free discussion. Norwegian Journal of Entomology 53(2): 387-393

The present article presents a summary of an open discussion at the 13(th) International Congress of Myriapodology held in Bergen 24 to 29 July 2005. In insects and most myriapods, the attribution of dorsal to ventral parts of segments poses no problems. In contrast, the correspondence between leg-pairs, sternites and tergites in millipeds (Diplopoda) is not obvious and has led to conflicting interpretations. Three different schemes which had been developed by morphological and embryological investigations were presented and discussed during the session. A possible solution to the problem has been proposed based in investigations on expression of segmentation genes. Obviously, there is an autonomy and a decoupling of dorsal and ventral segmentation processes in millipedes. Some other questions like the proposition of a stepwise subdivision of larger units into smaller metameres and the evolution of segmentation in general have been discussed cursorily.
