Miers, 1879 s. str. is an amphi-American genus with 12 species. This genus is characterised by the pyriform or triangular carapace, densely covered by short, velvet-like setae; with well-developed bifurcated or parallel rostral spines; the eyes completely protected by the orbits when retracted; orbits composed by the pre-orbital and the post-orbital spines and one or two projections of the basal article of antenna forming a functional, laterally projected protective hood. Although some of these characters can be observed in
