Mianeuretus mirabilis Holotype queen

There are two fossil species in this genus, Mianeuretus mirabilis, known from Florissant shale (Oligocene) in the United Sates and the other species Mianeuretus eocenicus from Middle Eocene (Lutetian) Green River Formation, Colorado, USA. At this time Mianeuretus is placed within the Aneuretinae.


Female. - Moderate size; head distinctly longer than broad, rounded, slightly narrowed anteriorly; sides convex; eyes large, ocelli present; mandibles triangular, with blunt teeth; antennae slender, with eleven subequal segments; thorax about as broad as the head; petiole much longer than broad, surmounted posteriorly by a small node; gaster of moderate size. (Venation unknown)


One specimen from Florissant, Colorado, United States (Late Eocene) and the other from Green River Formation, Colorado, United States (Lutetian, Middle Eocene).
