Original evidence / species identification
2024 Japanese study: treated as an introduced taxon across studied regions; 2025 authors defended it as distinguishable from N. denticulata.
Illustrated research / ancestry evidence
Other taxonomic treatments
Species label widely used for Cherry, Sakura, Blue Dream etc. NCBI currently uses N. davidi, with heteropoda as synonym.
Contradictions and unresolved claims
2024 Chinese mitogenomic paper proposes synonymization with N. denticulata; 2025 Cai/Shih disagree.
Ecological and breeder-pedigree limits
2024 Japan specimens: non-indigenous at study sites; does not establish universal origin of commercial lines.
Recorded commercial founders
Not documented in cited field taxonomy
Published, counted named-color F1/F2 ratios
No controlled commercial color F1/F2 segregation table in cited source
Primary scientific and database references
- Shih, Cai, Niwa, Yoshigou & Nakahara (2024), integrative identification of Neocaridina in Kyushu and Honshu
Peer-reviewed original field specimens, morphology and COI. Eight species / provisional lineages detected locally, not aquarium commercial founder certificates
- Yang, Cui, Li, Dong, Kang & Gan (2024), N. davidi–denticulata–heteropoda mitogenome proposal
Peer-reviewed mitogenomic taxonomy hypothesis. Proposal to synonymize under N. denticulata is contested by other taxonomists, and not an official universally resolved species consensus
- Cai & Shih (2025) reply to Fuke, clarifying competing taxonomic interpretations
Peer-reviewed published response, Dec 3 2025. Authors defend distinct N. davidi and N. denticulata using integrated taxonomy; the published exchange documents unresolved disagreement
- NCBI taxonomy (N. davidi current name, N. heteropoda alternative synonym)
Curated database annotation, not nomenclatural authority. NCBI explicitly warns users to consult taxonomic literature, especially in a contested case
