Classification and published species name
Caridina serrata — formally described 1860
Picture-style taxon evidence tree
Wild distribution context
Southern China / Hong Kong
Diagnosis and study methods
Name-bearing reference for C. serrata complex; 2026 paper found traditional group polyphyletic (at least four mitochondrial lineages).
Taxonomic history and relationships
Restricted sensu stricto usage is narrower than the former broad morphology-first group.
Aquarium trade and false look-alikes
A group-level tree is NOT a single genealogical parent strain or evidence all member species interbreed.
Controlled breeding outcome counts
Not a controlled ornamental-breeding study
Molecular color gene evidence
No peer-reviewed commercial color locus assigned to this name by cited taxonomic sources
Conservation / handling caveat
Research identification of a wild species is not a commercial availability announcement. Avoid collecting, purchasing undocumented wild specimens or inferring permissive collecting regulations.
