Distribution in Argentina.

Buenos Aires, Catamarca, Córdoba, Jujuy, La Pampa, Salta, and Tucumán ( Lareschi et al. 2016).

Material examined.

Capital Department : (9) Cuesta La Cébila, 22 km NW of Chumbicha, by route 60 (28°50'S, 66°24'W), 1066 m Akodon glaucinus , 25.IX.1993, CML (3751), 1 ♀ CMLA (674) .

Remarks.

The main morphological characters that distinguish P. acodontis from the other known species of genus are: in males, the distal arm of sternum IX with a dense fringe of setae along its ventral margin and sternum VIII is strongly emarginated ventro-apically; in females the posterior margin of sternum VII presents a drawn-out median lobe (Smit, 1987). This is the first record of this species for La Rioja Province. The locality of the Material Examined corresponds to the Monte Desert of Mountains and Isolated Valleys eco-region.
