Review of Leucospilomutilla Ashmead and Description of the New Genus Atlantilla (Hymenoptera: Mutillidae).

The new genus Atlantilla Williams & Bartholomay, gen. nov. (type species Mutilla auriculata Gerstaecker, 1874), is proposed based on the combination of previously undescribed males from the Atlantic Forest and females of Traumatomutilla auriculata (Gerstaecker, Arch Naturgesch 40:41-77, 1874). This genus is similar to Leucospilomutilla Ashmead, 1903, which is also reviewed here. The previously unknown male of L. staurogastra Suárez, 1973 is described. Keys and illustrations are provided for each of the three known Leucospilomutilla species.
