SPECIES Trinomys iheringi

Author:Thomas, 1911.
Citation:Ann. Mag. Nat. Hist., ser. 8, 8: 252.
Common Name:Ihering’s Atlantic Spiny-rat
Type Locality:Brazil, São Paulo, São Sabastião Isl.
Distribution:Mainland and offshore islands of the states of São Paulo and Rio de Janeiro (E Brazil).
Status:IUCN – Lower Risk (lc) as Proechimys iheringi.
Comments:Reviewed by Pessôa and Reis (1996), who recognized the six subspecies listed by Moojen (1948: bonafidei, denigratus, gratiosus, iheringi, panema, paratus) plus the newly described eliasi. Pessôa and Reis (1994) concluded that bonafidei, denigratus, eliasi, gratiosus, panema may be part of a taxon specifically distinct from iheringi. Lara and Patton (2000) concluded that bonafidei and gratiosus were not allied with iheringi and elevated gratiosus to a species and retained bonafidei as a subspecies of gratiosus. Lara and Patton (2000) also elevated eliasi and paratus to species and concluded that denigratus was a subspecies of setosus. The sister taxon of iheringi is dimidiatus (Lara and Patton, 2000). Karyotype has 2n=60-65 depending on the number of B chromosomes (Yonenaga-Yassuda et al., 1985).
