Original evidence / species identification
Shih et al. report Japanese native specimens (COI plus morphology) and distinguish N. denticulata from introduced N. davidi.
Illustrated research / ancestry evidence
Other taxonomic treatments
Yang et al. propose applying this name to a broad complex containing davidi, heteropoda, sinensis.
Contradictions and unresolved claims
Fuke challenges distinctions; Cai/Shih rebut. Do not announce either nomenclatural theory as universally settled.
Ecological and breeder-pedigree limits
Native status applies to particular documented Japanese field populations in studies, not every commercial shrimp sold as denticulata.
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
- 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
