[ Cerradomys ] maracajuensis: Weksler et al., 2006: 8 .
TYPE LOCALITY: ‘‘ Brazil, Mato Grosso do Sul: Municipality of Maracaju (approx. 21 ° 389S, 55 ° 099W) Fazenda da Mata’ ’.
GEOGRAPHIC DISTRIBUTION: The known collection localities of C. maracajuensis (figs. 1, 2) are distributed across the Brazilian Cerrado on Minas Gerais, Mato Grosso do Sul, and Mato Grosso to Paraguayan open areas of Amambay, Caaguazu, Canendiyu, Paraguari, La Cordillera, San Pedro, and Concepcion. To west, C. maracajuensis penetrates the open vegetation lowlands of Bolivia, at Beni, Santa Cruz, and La Paz, and Peru, at Puno. Most records are from lowlands although there are also records of specimens from highlands and dissected highlands of central South America; the known altitudinal range varyies from 102 m (Tacuati, Paraguay; USNM 293154) to 1750 m (Pitiguaya, Bolívia; e.g., AMNH 72641).
DIAGNOSIS: C. maracajuensis is characterized by large body and tail size (HBL range: 140–185 mm; TL range: 171–227 mm; see table 3), long and more robust feet (HF range: 34–43 mm), dorsal body color coarsely grizzled, buffy brown to orange brown, ventral body color grayish to buffy to yellow gray, skull (figs. 4, 6) with shallow rostral fossa, mesopterygoid fossa with small and narrow sphenopalatine vacuities or fully ossified, shallow palatal fossae (simple and large posterolateral palatal pits), developed palatal excrescences, mesolophid developed (narrow and reduced in few individuals from Bolivia), central cartilaginous digit of distal baculum absent, and a unique chromosomal formula (2n 5 56, FN 5 58).
KARYOLOGY: Diploid number of 56 chromosomes and low fundamental number of 58 autosomes are diagnostic for this species when compared with other congeneric species (see Bonvicino et al., 1999; Langguth and Bonvicino, 2002: fig. 3).
NATURAL HISTORY: Available data on museum specimens relating to the natural history of C. maracajuensis report habitat preference: Near the type locality, Maracaju, specimens were collected in some distinct habitats like ‘‘woods’’, ‘‘bush and grass’’, ‘‘Brush pile in

grass at edge of rice field’’, ‘‘Brush-Swampy’’, ‘‘Forest’’, and ‘‘Brush and grass’’ (R.M. Gilmore, in museum tags at AMNH and MN), but also in gallery forest ( Langguth and Bonvicino, 2002). In Bolivia, specimens were collected in dense shrub-grass field (cleared forest), dense forest adjacent (G. Schmitt, AMNH tags). Pregnant females were observed in Bolivia during June and September, with two and four embryos ( Anderson, 1997).
