Comments. The morphological characters observed in the specimens agree with the original description and subsequent redescriptions given by Sutton & Durette-Desset (1991) and Suriano & Navone (1992), i.e. relatively large body (7–13 mm.), synlophe with 22 ridges stout and oriented perpendicularly to body surface, subsymmetrical caudal bursa with lateral pattern of type 2-2-1, well-developed dorsal lobe with dorsal ray distally divided and short spicules (230-310) in relation to body length.

Trichofreitasia lenti was originally described by Sutton & Durette-Desset (1991) in Oligoryzomys flavescens (Waterhouse, 1837) from Buenos Aires province, Argentina. Shortly after, Suriano & Navone (1992) described Hassalstrongylus multiovatus in Akodon simulator (Thomas, 1916) from Tucuman province, Argentina. Later, Digiani et al. (2007) synonymized it with T. lenti . This species was also recorded for A. montensis, A. cursor and O. nigripes from Serra dos Órgãos, Rio de Janeiro, Brazil (Simões et al. 2011).

This is the first record of this species in Misiones province, Argentina.
