The color syndrome of species in the genus Odontomutilla Ashmead, 1899 (Hymenoptera: Mutillidae), and a description of two new red-headed species

Of 100 taxa of Odontomutilla that were studied 27 expressed the Red-headed Color Syndrome (RHCS), 73 expressed the Black-headed Color Syndrome (BHCS). The ratio of species with RHCS to species with BHCS is highest in the Oriental region (1.5), while in the Afrotropical region is 0.07. Two species of the genus Odontomutilla with RHCS from two different groups are described: O. storozhenkoi sp. nov.

(female with lateral felt line on metasomal tergum 2 linear in form) from the Palaearctic (Iran: Loristan, Chaharmahal and Bakhtiari) and O. williamsi sp. nov. (female with lateral felt line on metasomal tergum 2 forming a deep, ovate, densely setose pit) from Laos and Vietnam (Oriental region). Former is the second species of Odontomutilla in the Palaearctic and related with species from the Afrotropical region.

The latter belongs to the small group of the genus with three spots on metasomal tergum 2 in female.
