RAMIREZ, Martín J  y  GRISMADO, Cristian J. Description of the spider Verita williamsi, a new genus and species from Santa Fe, Argentina (Araneae, Gnaphosidae). Rev. Mus. Argent. Cienc. Nat. [online]. 2015, vol.17, n.2, pp.173-182. ISSN 1853-0400.

Verita williamsi, new genus and species (Araneae, Gnaphosidae) is described from specimens recently collected in Northern Santa Fe Province, Argentina. The peculiar combination of having only two piriform gland spigots, aligned setae on the leg scopulae, and anterior lateral spinnerets not widely spaced suggests that the species is probably a close relative of Micaria and some of the small representatives of the Anzacia group of genera. It differs from all of them by having three teeth in the cheliceral retromargin and lacking iridescent squamose scales in the abdomen.
