The lace bug Dictyla labeculata (Uhler) was described in 1893 from the dry desert of southeastern California's Argus Mountains based on specimens taken on singleleaf pinyon (Pinus monophylla Torr. and Frém.). Subsequent records of this seldom-collected species have been mostly from arid regions of western North America (British Columbia south to Arizona and New Mexico), except for a biogeographically incongruous record from Quebec, Canada. Nebraska is a new state record and the easternmost in the United States based on nymphs and adults found on reproductive structures of James's cryptantha (Cryptantha cinerea [Greene] Cronquist var. jamesii [Torr.] Cronquist) in the Sandhills (June and July, 2020–2022). Idaho is a new state record based on a specimen in the U.S. National Museum of Natural History. The Nebraska study provides the first host plant record for the lace bug. Collections of adults from other plants, such as singleleaf pinyon, are considered incidental or overwintering occurrences. A search for details of the lace bug's collection in Quebec, published without comment in a list of Tingidae from the province, revealed that neither a misidentification nor mislabeling was involved and that the record, albeit anomalous, probably is valid. Because P. R. Uhler did not mention certain details in describing the new species, the collector's name (Albert Koebele) and collection site within the Argus Range (Maturango Spring) are provided. Insect collecting as part of the Death Valley Expedition of 1893 to the western states, during which the lace bug and numerous other new species were discovered, is noted.
