Synalpheus Charon
''Synalpheus'' is a genus of snapping shrimp of the family (biology), family Alpheidae, presently containing more than 100 species; new ones are described on a regular basis, and the exact number even of described species is disputed. ''Zuzalpheus'' The genus ''Zuzalpheus'' was established for ''S. gambarelloides'', ''S. brooksi'', and their closest relatives, which contain several notably eusocial species. While these do seem to form a clade, it is not fully resolved whether or not they are indeed the sister taxon of all the remaining ''Synalpheus''. However, a detailed cladistic study of morphological characters found well marked differences between the proposed two genera and concluded that the supposed species groups around ''S. biunguiculatus''/''S. coutierei'', ''S. brevicarpus'' and ''S. neomeris'' are neither clearly defined nor, as it seems, monophyletic, while the group separated in ''Zuzalpheus'' was clearly distinct in characters of the m ...
