OTT, Ricardo. Neodrassex, a new genus of the Leptodrassex group (Araneae, Gnaphosidae) from South America. Iheringia, Sér. Zool. [online]. 2012, vol.102, n.3, pp. 343-350. ISSN 0073-4721. http://dx.doi.org/10.1590/S0073-47212012000300015.
The new genus Neodrassex is proposed to include two new species of Gnaphosidae from Brazil. Neodrassex aureus sp. nov. is described from Amazonas, Paraná and Rio Grande do Sul states, and N. iguatemi sp. nov. is described from Paraná state. Neodrassex gen. nov. is characterized by small size, pale coloration, large anterior median eyes surrounded by black pigmentation, absence of a dorsal abdominal scutum in males and by the cheliceral dentition with 2-3 teeth on the promargin and 2-4 on the retromargin. The new genus is tentatively placed at the Leptodrassex group.
