 Diagnosis. The elytra are reddish brown and lack any maculation as in the other species.   
 Description. Length 7.4–9.9 mm; width 5.6–9.0 mm. Dorsum reddish­brown. Head, ventral surface and legs reddish­brown, antenna yellow. Pronotum edges smooth and hemispherical, posterior edge blackish; faint median groove; anterior margin straightish over head; prosternal collar well­defined, protuberant; prosternal process slightly inflated posteriorly with shallow anterior groove; posterior margin not projected at scutellum. Scutellum visible externally, shiny and smooth. Elytral base not broader than pronotum; anterior margin blackish; suture flat; explanate margins narrow and tapered posteriorly; punctation (Fig. 3) similar on disc and explanate margins. Metasternum 3 times wider than long, distorted and concave. Spermathecal duct short, with 2–6 coils.   
 Type. Lectotype and one paralectotype, designated by Borowiec (1999). Locality label: ‘‘ Domingo,’’ Naturhistoriska Riksmusset, Stockholm, Sweden.   
 Specimens Examined. Lectotype and paralectotype, and eighty one specimens (males and females), with the following label data:

 Variation. One specimen was distinctly yellow, probably due to collecting and storage conditions.   
 Remarks. One specimen (SMCC) bears the label ‘‘beating branches in semi desert.’’ Several specimens (INHS) collected by S. W. Sanderson came with a handwritten note ‘‘to attach to the host label: Ipomoea nr. itiliacea,’’ and another (USNM) has the host data ‘‘on Acacia. ’’ These represent the first plant records associated with this genus, but they should be confirmed as hosts. Two specimens (AMNH) bear the label: ‘‘Athens, Ga.’’ Given the known distribution, I consider these mislabelled.
