Chlamydatus auratus?: Scudder, 1997: 271 (list).

DIAGNOSIS: Recognized by the brown coloration, the frequent submacroptery in the female, the size, and the form of the male genitalia. Most easily confused with C. keltoni and C. pulicarius by the frequent occurrence of submacroptery/brachyptery (figs. 1, 2), but total length in C. pulicarius always 2.51or more as opposed to total length of 2.41 or less in C. pullus , and male genitalia more highly convoluted and vesica with a longer apical process in C. pulicarius (fig. 5) than in pullus (fig. 6); coloration of appendages variable in C. pullus and similar to that found in C. pulicarius . Distinguished from C. keltoni , in which submacroptery/brachypterous found most frequently only in females, by the paler coloration of the femora in some specimens of C. pullus and by the form of the male genitalia (compare figs. 4, 5). Possibly also confused with C. uniformis on the basis of size, but that species jet black with all legs entirely black and occurring in southern California and adjacent northern Mexico, whereas C. pullus with at least tibiae always pale (figs. 2, 3) and restricted to much higher latitudes.

HOSTS: No host records from North America.

DISTRIBUTION: Holarctic, occurring only at higher latitudes.

DISCUSSION: Chlamydatus pullus was recorded as being widely distributed in Alaska and Canada and as also occurring in New Mexico by Kelton (1965), but with no mention of a specific locality for the last record. As indicated in our discussion under C. keltoni , we consider most, if not all, of Kelton’s records of C. pullus to represent misidentifications. Scudder (1997) tentatively placed specimens of this species from the Yukon and Northwest Territories in auratus , noting that they had different antennal and leg coloration than reported by Kelton (1965). We have compared the Yukon material with authoritatively identified C. pullus specimens from Russia and consider them conspecific.

The identity of Chlamydatus fulvipes Knight was always problematical to us. The male genitalia were not illustrated by Kelton (1965) and the species was known only from the three specimens of the type series from Minnesota. We compared the holotype of C. fulvipes with true C. pullus and found them to be conspecific new synonym. The male genitalia of the holotype were regrettably destroyed by the senior author during the process of preparing them for illustration. The male specimen illustrated in figure 2 from Cascapedia, Quebec, agrees closely with the holotype in all attributes.

Kelton (1965) recorded the host of this species as Plantago , but Knight’s material from the type locality does not bear host labels. Because of the history of misidentification of this species, we consider the host association of C. pullus in North America to be in doubt.
