TABLE 1 in A new subfamily classification of the highly diversified Dorippidae H. Milne Edwards, 1837 (Crustacea, Decapoda, Brachyura, Dorippoidea), using morphological, molecular and palaeotonlogical data, with special emphasis on its unique female reproductive system

TABLE 1. — Comparison of main characters between Dorippidae H. Milne Edwards, 1837 and Ethusidae Guinot, 1977. Abbreviations: see Material and methods.
