Type species.

Diagnosis.

Dangerfield et al. (1999) and Mercado and Wharton (2003) provided detailed diagnostic characters. Retusigaster can be easily distinguished from other cardiochiline genera by the combination of the following characters: eye seemingly bare (Figs 2C View Figure 2 , 3C View Figure 3 , 5C View Figure 5 ); clypeal tubercle absent (Figs 2C View Figure 2 , 3C View Figure 3 , 5C View Figure 5 ); mouthparts short (Figs 2C View Figure 2 , 3C View Figure 3 , 5C View Figure 5 ); scutellum apically with carinate margin (Key image 2); hind tibia without apical cuplike projection (Figs 2A View Figure 2 , 3A View Figure 3 , 5A View Figure 5 ); ovipositor and ovipositor sheath short (Figs 2A View Figure 2 , 3A View Figure 3 , 5A View Figure 5 ); hypopygium entirely sclerotized and ventro-apically blunt (Figs 2A View Figure 2 , 3A View Figure 3 , 5A View Figure 5 ).

Distribution.

Nearctic region (Canada, USA, Mexico), Neotropical region (Jamaica and Mexico), Palearctic region (Kazakhstan, Mongolia, Turkey, Turkmenistan).

Biology.

Potential food sources of two species of Retusigaster are found. A member of R. arugosus was collected on cotton ( Gossypium sp.; Malvaceae ) in Texas, and a specimen of R. purshi sp. nov. was collected on Mexican cliffrose ( Purshia mexicana (D. Don) S. L. Welsh; Rosaceae ) in Nevada.
