| Popis: | 28. Foster’s Punare Thrichomys fosteri French: Punaré de Foster / German: Foster-Punaré / Spanish: Punaré de Foster Taxonomy. Thrichomys fosteri Thomas, 1903, “Sapucay,” Paraguari, Paraguay. Thrichomys foster: was considered a subspecies of T. apereoides (sensu lato) by S. Anderson in 1997. It was included as a junior synonym of T. pachyurus by L. M. Pessoa and colleagues in 2015, butits karyotype differs from that species (2n = 34, FN = 64 vs. 2n = 30, FN = 56) and its position as a molecular clade basal to one collectively joining 7T. apereoides, T. laurentius, and T. pachyurus. Monotypic. Distribution. SC Brazil (Mato Grosso and Mato Grosso do Sulstates) and Paraguay. Descriptive notes. Head—body 119-225 mm, tail 111-200 mm; weight 350 g. Dorsum of Foster’s Punare is generally ash-gray, with ventral hairs completely white or light gray at bases; dorsal tail hairs are blackish brown, sharply contrasting color of middorsum; and underside oftail is whitish gray. Its shares distinct cranial characteristics with the Jacobina Punare (7. inermis) and the Pantanal Punare (71. pachyurus), including wide incisive foramina with slight lateral constriction at premaxillomaxillary suture and broadened, rectangular hamular processes of pterygoid bones. Foster's Punare (7. foster) and the Pantanal Punare have broad, robust skulls, large and inflated auditory bullae, wide jugal dorso-ventrally, paroccipital processes that are not appressed to each bulla, and wide plates (c.2 mm) between oval and masticatory foramina; this combination of characteristics separate both species from the Jacobina Punare. Habitat. Southern Cerrado ecoregion at elevations of 90-370 m. Foster’s Punare is considered a rocky outcrop specialist within dry forest communities. Food and Feeding.
