Chlamydatus schuhi Knight, 1964: 141 (n.sp.). Chlamydatus knighti Kelton, 1965: 1140 (n.sp.,

host). NEW SYNONYMY.

DIAGNOSIS: Recognized by the relatively small size, total length 2.66 or less, the pale fore­ and middle femora contrasting with the dark hind femora, and by always having a portion of the hemelytra—and often the posterior margin of the pronotum—pale and somewhat greenish. Most easily confused with pale specimens of C. obliquus on the basis of coloration of dorsum and legs, but total length in that species always 2.78 or greater, whereas total length in C. schuhi never more than 2.66.

HOSTS: Most frequently collected on the Polemoniaceae ( Leptodactylon sp. and Phlox sp. ) and the Asteraceae ( Chrysothamnus spp. ).

DISTRIBUTION: Great Basin of western North America.

DISCUSSION: Kelton (1965) described Chlamydatus knighti on the basis of specimens from Utah and eastern Washington. He compared his material with specimens of C. schuhi from British Columbia , which he indicated were identified by Knight. Although Kelton believed size, coloration of the pronotum, and form of the male genitalia to be diagnostic for these two nominal species, after having examined large numbers of specimens, including the types and associated material, from a variety of localities and hosts, we can find no constant differences in coloration, size, or genitalic structure to support the distinction. The distributions are also grossly overlapping suggesting variation rather than discrete differences. Furthermore, the phenotypes of both C. schuhi and C. knighti occur in more than one series from a single locality and host. We therefore treat these names as synonyms new synonymy. Although Kelton (1965) illustrated the male genitalia of the two nominal species as distinctive, our comparison suggests that his rendering of the vesica for C. schuhi is in error.
