Classification and published species name
Caridina argilla — formally described 2026
Picture-style taxon evidence tree
Wild distribution context
Hong Kong
Diagnosis and study methods
Original integrative study differentiates cryptic species from previously identified specimens with anatomical character suites and COI/16S.
Taxonomic history and relationships
One of three formally described in Zoological Studies 65:04; historically near look-alike members of a polyphyletic assemblage.
Aquarium trade and false look-alikes
No evidence that a named aquarium-pattern trade label uniquely identifies this species.
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.
