Monodelphis (Microdelphys) iheringi

(Thomas, 1888)

TYPE MATERIAL AND TYPE LOCALITY: BMNH 82.9 .30.43, the lectotype (designated by Thomas, 1888a; see Remarks), consists of the fluid-preserved carcass and extracted skull of an adult male collected at Taquara (29.65° S, 50.78° W; 29 m), Rio Grande do Sul state, Brazil .

SYNONYMS: None.

DISTRIBUTION: Monodelphis iheringi occurs in the Atlantic Forest of southeastern Brazil, from Espírito Santo to Rio Grande do Sul (Pine and Handley, 2008: map 40).

REMARKS: The original description of this species ( Thomas, 1888b) was evidently based on several specimens, none of which was designated as the unique name-bearer, but the fluid-preserved male from Taquara was subsequently designated as such by Thomas (1888a). For descriptions, measurements, and morphological comparisons with sympatric congeners, see Duda and Costa (2015) and Abreu and Percequillo (2019). Pavan et al. (2014) reported that a specimen of Monodelphis iheringi from Rio de Janeiro differed from material collected in Espírito Santo and São Paulo by an average uncorrected sequence distance of 8.2% at the cytochrome b locus, a sufficiently large value to justify closer study of the corresponding voucher material.
