Linn. Soc. Lond., 11: 161 . Type Locality: Trinidad and Tobago , Trinidad . Vernacular Names: Caribbean Spiny Pocket Mouse . Subspecies: : Subspecies Heteromys (Heteromys) anomalus subsp. anomalus Thompson 1815 Subspecies Heteromys (Heteromys) anomalus subsp. brachialis Osgood 1912 Subspecies Heteromys (Heteromys) anomalus subsp. hershkovitzi Hernández-Camacho 1956 Subspecies Heteromys (Heteromys) anomalus subsp. jesupi J. A. Allen 1899 Distribution: N Colombia , including Magdalena Valley, east to N Venezuela , Trinidad , Tobago , and Margarita Isl. It does not enter Panama (contra Rogers, 1990 ; Méndez, 1993; Williams et al., 1993 ; Nowak, 1999 ; see Anderson, 1999 [2000]). Conservation: IUCN – Lower Risk (lc). Discussion: Subgenus Heteromys . Subspecies listed by Williams et al. (1993) and distribution mapped by Eisenberg (1989) and Anderson (1999 [2000]). As currently understood, anomalus is likely composite. Anderson (2002) recently described H. oasicus from NW Venezuela , a taxon that Handley (1976) regarded as distinct from anomalus . Populations from the Cordillera de la Costa of Venezuela , above 1000 m , also represent an undescribed species ( R . P. Anderson, pers. comm.).
