Two new genera in the family Lycosidae Sundevall, 1833 from Argentina are proposed. Lobizon gen. nov. comprises five species: Lobizon corondaensis (Mello-Leitão, 1941) comb. nov. (type species), L. minor (Mello Leitão, 1941) comb. nov., and L. humilis (Mello-Leitão, 1944) comb. nov., all these with a wide distribution in Argentina, and two new species: L. ojangureni sp. nov. from the montane forests of Northwestern Argentina, and L. otamendi sp. nov. from the northeastern Buenos Aires Province. The monotypic Navira gen. nov. is erected for N. naguan sp. nov. from Córdoba and San Luis Provinces. Trochosippa anomala (Mello-Leitão, 1945) and Alopecosa unguiculata Mello-Leitão, 1944 are considered junior synonyms of L. corondaensis and L. humilis respectively. A putative synapomorphy uniting the two genera is the massive, greatly elongated terminal apophysis which is grooved along its length. The subfamily placement of the two new genera is briefly discussed, and it is concluded that they probably belong to the Artoriinae Framenau, 2007 or Venoniinae Lehtinen & Hippa, 1979.
