Original evidence / species identification
2024 survey reports an unidentified lineage close to denticulata, potentially cryptic native.
Illustrated research / ancestry evidence
Other taxonomic treatments
Aff. label indicates taxonomic affinity pending stronger delimitation.
Contradictions and unresolved claims
The 2024–25 commentary exchange disputes some identities and mtDNA topology, and cannot be shortcut using color phenotype.
Ecological and breeder-pedigree limits
Do not advertise as a formally described species or collect from natural habitat.
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
- Yusuke Fuke (2024) scholarly commentary on Japanese Neocaridina delimitations
Published comment challenging alternative field assignments. A critical interpretation of earlier specimens/markers, not a complete independent reference-wide taxonomic resolution
- 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
