FIGURE 9 in Taxonomic review of the slender mouse opossums of the "Parvidens" group from Brazil (Didelphimorphia: Didelphidae: Marmosops), with description of a new species
FIGURE 9. Dorsal view of the braincase of Marmosops species. A, M. woodalli (UFMT 3966 ♁); B, M. pinheiroi (MPEG 40017 ♁). Abbreviations: ip, interparietal; par, parietal; sup, supraoccipital. Note the rounded and markedly convex shape of the supraoccipital in M. woodalli and the slightly convex shape of this bone in M. pinheiroi. Scale bar 5 mm.
FIGURE 7 in Taxonomic review of the slender mouse opossums of the "Parvidens" group from Brazil (Didelphimorphia: Didelphidae: Marmosops), with description of a new species
FIGURE 7. Occlusal view of upper molars M2–M4 of Marmosops species. A, M. marina sp. nov (UFMT 1427, Paratype ♁); B, M. parvidens (MPEG 40403 ♁); C, M. woodalli (MPEG 38667 ♁). Abbreviations: alci, anterolabial cingulum; prprcr, preprotocrista. Note the presence of a continuous shelf along the anterior margin of crown of the upper molars formed by the preprotocrista and the anterolabial cingulum in both M. marina and M. parvidens, which is narrow in the former (constriction indicated by arrows) and wide in the latter species. This condition is absent in M. woodalli. Scale bar 1.65 mm.

FIGURE 6. Occlusal view of upper molars M2–M4 of Marmosops. A, M. marina sp. nov. (UFMT 4081 ♁ Paratype); B, M. woodalli (MPEG: AGPM 109 ♀). Abbreviations: mecl, metaconule; mec; metacone; pac, paracone; prc, protocone. Note the presence of a metaconule on the M3 in M. marina, and a labial projection of the posterior portion of the stylar shelf in relation to the anterior portion on M3 in M. woodalli. Scale bar 1.6 mm.

FIGURE 5. Distribution (polygons) and collection localities (symbols) for Marmosops species of the "Parvidens" group in- cluded in this report: M. parvidens (yellow circles); M. pinheiroi (stricto sensu; green circles); M. woodalli (red circles); M. marina sp. nov. (blue circles); sympatry between M. parvidens and M. pinheiroi (s. s.; crosses); type localities (stars). The ranges of M. parvidens and M. pinheiroi were partially based on Voss et al.
