This site would not have arisen without the help of several people.
I would like to thank:
Dr Paul Marsh, Dr Sergey Belokobylkij, Dr Augusto Loni, Dr Eduardo Shimbori, Miss Touret-Alby Agnièle (MNHN) who provided some photos;
Dr Cees van Achterberg, Dr Bob Zuparko who lent some specimens here illustrated;
Dr Pascal Rousse, Dr Eduardo Shimbori for their supports;
Hélène Dumas for her review, suggestion and photos.
To be continued...
