This estimation is reported on figure 9 where evolution of number of species within the years is illustrated. Number of Polynesian Decapoda and Stomatopoda will thus exceed 800 species. Moreover, it appears that researches conducted after 1980 (CRIOBE Moorea studies and RV Marara campaigns) have generated 322 new records, an increase of 74 % ! If this effort was continued in the future, it is to be expected that regional fauna will reach the level of a thousand species.

The main trend, as generally admitted, would be towards a decreasing biodiversity from Indonesia and Australia to French Polynesia. For example, BRUCE (1990: 13) mentioned 168 Australian pontoniins for only 36 in French Polynesia. However, this difference is probably amplified by imperfection of our data, and could be reduced when pontoniids are better studied in French Polynesia. In fact, for genera that have been well studied, biodiversity appears only slighly lower, or even greater, than in western Pacific. For example Plesionika count 21 species in French Polynesia vs 29 i
