Head—body 215-493 mm,tail 120-207 mm; weight 300-800 g. Steeres Spiny-rat is one of the largest species of terrestrial spiny-rats. Its ears and hindfeet are large, and tail is c.65% of head-body length, bicolored dark above and pale below, and covered with fine hairs but with scales conspicuous to the eye. There are typically 8 annuli/cm. Dorsum is light reddish brown, only faintly streaked with darker hairs. Steeres Spiny-rats vary in the degree to which they are darkened along midline, but in general, they lack dark midline characteristic of most specimens of the Napo Spiny-rat (P. quadruplicates). Venteris pure white, and texture of ventral fur is thicker and more velvety both to the eye and touch than in other species of

Color of dorsal surface of hindfootis characteristic, with pale to dark brown outer band and whitish inner band along length of foot from tarsal joint to end oftoes. Skull of Steeres Spiny-ratis large, with long and narrow rostrum and well-developed supraorbital ledge that extends onto parietals as weakly developed ridge. Incisive foramina are lyrate to oval in outline, with slightly to strongly flanged posterolateral margins that

extending onto anterior palate; premaxillary part of septum is short, less than one-half the length of opening; maxillary part is distinctly narrow; both parts of septum are in contact in most specimens; and vomer usually is not visible. Groove is present on floor of infraorbital foramen, butlateral flange is only weakly developed. Mesopterygoid fossa is relatively broad (averaging 67°) but penetrates to midpoint of M. Counterfold pattern is 3(4)-3(4)-3(4)—(3)4/4-3-3-3. Baculum is comparatively short (length 7-1-8-7 mm) and of moderate width (proximal width 2-5-2-9 mm; distal width 2-5-3-1 mm), with parallel or slightly concave sides; it is similar in size and shape to those of the Napo Spiny-rat and Goeldis Spiny-rat (

Seasonally flooded rainforest in the dry season, such as blackwater igap6 and whitewater varzea, but margins of adjacent terra firma forest in the wet season, including secondary forests, abandoned garden plots, riverine margins, and flooded grass patches within forests at elevations of 50-400 m. Overits entire distribution, Steeres Spiny-rat is the only species present in igapo or varzea.

Steeres Spiny-rat feeds mainly on fruit, fungi, and seeds, with lesser amounts of plant material and arthropods. Consumption of sporocarps of micorrhizal fungi and seeds suggest that Steeres Spiny-rat may play a key ecological role in seed and fungal dispersal in forests.

Both sexes reached sexual maturity at an early age, well before complete molt into their adult pelage; pregnant females, on average, were younger (based on tooth wear) than those of adjacent, terra firma species; almost all females participated in breeding with a large proportion (20%) exhibiting evidence of postpartum estrus (simultaneous pregnancy and lactation); and litter sizes were high for a species of

Classified as Least Concern on The IUCN Red List. Steeres Spiny-rat is widespread and specializes in riverine, seasonally flooded forest that is not under threat from agricultural expansion. It is part of the fauna in a number of protected parks and indigenous areas and is unlikely to be declining. Expansion of illegal gold mining along many major river systems through its distribution, especially in south-eastern Peru, might impact varzea habitat, and focused field studies are needed to assess this possible threat. Additional studies on distribution, habitat, abundance, ecology, and conservation threats to Steeres Spiny-rat are needed.
