Site of infection. small intestine

Collection number. MLP-He 7325

Host species. Akodon montensis . CG169

Comments. The morphological characters observed in the specimens agree with the original description given by Rêgo (1967), especially regarding the shape and length of hooks in the rostellum. However, some differences were noticed as for the length and width of scolex, length of rostellum, diameter of suckers, length of cirrus pouch and diameter of eggs. These morphometric differences can be attributed to a greater number of specimens studied.

Rodentolepis akodontis was described parasitizing Necromys lasiurus (Lund 1840) (= A. arviculoides ) ( Rêgo 1967) and later parasitizing A. montensis , Akodon cursor Winger, 1887 and O. nigripes in Brazil ( Simões et al. 2011).The latter reports did not include morphological data. Guerreiro Martins et al. (2014) reported Rodentolopis. cf. akodontis from Oxymycterus rufus (Fischer 1814) in several localities extending from the province of Corrientes to the province of Buenos Aires, Argentina.

This finding enlarges the geographical distribution of R. cf. akodontis including the province of Misiones in Argentina.
