Treatment

Oligoryzomys fornesi Massoia 1973 , Rev. Invest. Agropec. Ser. 1, Biol. Prod. Anim., 10: 22.

Type Locality: Argentina, Formosa Prov., Naineck.

Vernacular Names: Fornes' Colilargo.

Distribution: NE Argentina, E Paraguay, and SC Brazil (Goiás to Paraíba; Bonvicino and Weksler, 1998).

Discussion: Viewed as a synonym of O. microtis ( Carleton and Musser, 1989; Olds and Anderson, 1987), an assignment contradicted by morphometric ( Bonvicino and Weksler, 1998) and cytochrome b ( Myers et al., 1995) data. Bonvicino and Weksler (1998) recorded the species as present in Brazil, but Andrades-Miranda et al. (2001 a) did not. Bonvicino and Weksler (1998) reidentified certain Paraguayan specimens reported as O. fornesi by Myers and Carleton (1981) as O. flavescens based on possession of lower diploid (62) and fundamental (64) numbers and certain cranial shape differences. Myers and Carleton interpreted these minor chromosome differences as populational variation (2n = 62-66, FN = 64-68), nor can we readily grasp the purported shape differences from Bonvicino and Weksler’s principle component results. Also see comments on O. flavescens .
