What the real molecular data support
The February 2026 study analyzed mitochondrial COI and 16S rRNA. It found the historical C. serrata group polyphyletic and comprising at least four lineages; the nominal-lineage C. serrata sensu stricto is distinguished by specific pereiopod, pleopod and uropodal characters. The graphic intentionally does NOT guess exact individual-species branch order.
What a Bee/Tiger breeder family tree would need
Voucher-confirmed identities for every wild founding specimen, dated mating records, sexed parent IDs and generation-specific F1/F2 phenotype counts. Such records are absent from these taxonomic works. Consequently Crystal Red, Taiwan Bee, King Kong, Galaxy, Tiger, Fancy Tiger and Pinto are not drawn as children of a particular scientific species.
Synonymy is not ancestry
The 2014 revision synonymized historical C. tumida with C. venusta. A synonym arrow means scientific naming treatment, not crossbreeding.
