Quediellus helenae Casey

Type material.

Holotype (female, United States National Museum of Natural History, not examined): "Helena Mont." / Casey bequest 1925 / Type USNM 48305 / Quediellus helenae Csy.

Smetana (1971) stated that the male lectotype was also a typical member of Q. nanulus . All available specimens from the Rockies were small-bodied, winged, with palisade fringe and narrow elytra. Subtle differences in the aedeagus were observed between individuals on either side of the continental divide (see Redescription below) but the single available barcode sequence from the east clustered deep within the western sequences of Q. debilis .
