The genus Emmenomma is revised and now includes three species from Southern Chile, Argentina and Falkland Islands (Islas Malvinas). The type species Emmenomma oculatum is redescribed and considered a senior synonym of E. beauchenicum. Emmenomma oculatum obscurum is removed from synonymy with E. oculatum, raised to the species level and redescribed; the male of this species remains unknown. A new species, Emmenomma joshuabelli sp. nov. is described. The presence of a grate shaped tapetum outside the Lycosoidea clade is described. Detailed images are provided for all known species.
