Abslract.- Atomosia arkansensis, new species, is described from specimens collected in blackland prairie in southern Arkansas, and Atomosia tibialis is reported the first lime from North America north of M exico. A new key to Nearctic A tomosia species is presented. Atomosia me/anopogon and A . mucida are noted to be sexually dimorphic. In addition to more standard characters, the open or closed condition of cell r5 and the length of the pedicel and flagellum relative to the length of the scape are used to distinguish similar species. Lectotypes are designated for Atomosia mucida, AlolllOsia puella, and Atomosia sayii. Atomosia echemon is synonymized with A . puella (new synonymy), and A. mucidoides is synonymized with A. sayii (new synonymy). Key Words: Diptera, Brachycera, robber fly, Asilidae, Alomosia, Nearctic
The New World genus Alomosia Mac for species identification and docs not quart consists of small, robust robber utilize some highly diagnostic morpho flies with elongate, slender antennae and logical characters, such as the relative a punctulate abdomen. It comprises sizes of the antennomeres and the more than 50 Neotropical species and condi tion of wing ccll rs. It is also a fewer than lO N earctic species (Martin confusi ng key in that some species key and Papavero 1970, Poole 1996, Scar out at more than one couplet.

Curran (1935) typic Neotropical genus Paratractia Hull published a new key that included seven with Alomosia. The North American Nearctic species and several Neotropical species arc notoriously difficult to iden spccics. Apparently, neither Curran nor tify using existing keys.
