SPECIES Proechimys semispinosus
| Author: | Tomes, 1860. | | Citation: | Proc. Zool. Soc. Lond., 1860: 265. | | Common Name: | Tome’s Spiny-rat | | Type Locality: | Ecuador, Esmeraldas Prov., Esmeraldas. | | Distribution: | SE Honduras to SW Ecuador. | | Status: | IUCN – Lower Risk (nt) as P. gorgonae, Lower Risk (lc) as P. semispinosus. | | Comments: | Placed in semispinosus group (Patton, 1987). Formerly included in amphichoricus; see Reig et al. (1980) who used the name centralis for animals assigned to semispinosus from N Venezuela. Gardner (1983b) discussed the taxonomic history of this species and corrected the type locality. Karyotype has 2n=30 and FN=50-54 (Gardner and Emmons, 1984; Patton and Gardner, 1972). Includes gorgonae based on lack of karyotypic difference between populations on Gorgonae Isl and mainland of Colombia (Gómez-Laverde et al., 1990). |
