As a result, 12 new extra-Michigan state records, comprising material from the Michigan State University Albert J. Cook Arthropod Research Collec-tion in East Lansing, the University of Mich-igan Museum of Zoology Insect Collection in Ann Arbor, and my personal collection, are herein reported.Materials and MethodsMethodology largely follows my pre-vious treatments (i.e., Swanson 2011, 2018, 2019):After examining the determined ara-did holdings and identifying much of the undetermined U.S. material in two Michigan university collections, the locality data of these specimens were compared with the most recent catalog for Heteroptera found north of Mexico (Henry and Froeschner 1988). Further records were culled after comparing with various post-1988 regional faunistic studies, as well as some pre-1988 references overlooked by the authors of the catalog (see annotations, plus Swanson 2011, 2018, 2019). The remaining specimen data are the subject of this treatment.The identification of all specimens included in this study was rendered or con-firmed by me, using my own keys (Swanson, unpublished) to the United States taxa syn-thesized from various sources (e.g., Parshley 1921, Blatchley 1926, Torre-Bueno 1939, Matsuda 1977). In most cases, I have con-firmed identifications previously rendered by R. F. Hussey.Label data were not copied verbatim, although complete locality information is included. Any additions, changes, or in-terpretive elements I provide are shown in brackets. Multiple localities are included, where possible, to fortify new records. Dis-tributional or taxonomic notes are offered where deemed necessary or useful.As mentioned, the authority on which a state having a published record for a given aradid species is based belongs to Froeschner (1988). An updated distribution within the United States and Canada is included for each species treated herein. Records over-looked or reported subsequently are annotat-ed in the distribution north of Mexico given at the end of each species account, whereas new records herein reported are presented in bold type; thus, this treatment also may be used as a partial compilation of references overlooked in Henry and Froeschner’s (1988) catalog. The abbreviations used for each U.S. state and Canadian province or territory follow the United States Postal Service and the Canada Post Corporation, respectively.Collections are designated as follows: Daniel R.

The following 8 states have new records: IL, KY, LA, MO, TN, VA, WI, WY.Subfamily ANEURINAEAneurus inconstans Uhler, 1871. – TENNESSEE: Carter Co., Roan Mountain, elevation 6300 ft., 6 August 1922, T.

Swanson 2012 [1 ♂, 1 ♀] (UMMZ).Distribution: USA: CT, DC, DE, IN, MA, MD, ME, MI (Swanson 2020), NC, NH, NJ, NY, OH (Osborn and Drake 1915), PA, RI, SD, TN, VA, VT; Canada: AB, BC, MB (Maw et al. 2000), NS, ON, QC, SK (Maw et al. 2000).Iralunelus politus (Say, 1831). – LOU-ISIANA: Orleans Co. [sic], New Orleans, 24 February 1923, T. H. Hubbell, det R. F. Hussey 1950 [4 ♀, 2 nymphs] (UMMZ).Notes: Kormilev and Froeschner (1987) raised the subgenus Iralunelus Štys, 1974 to full generic rank, at the same time treating Aneurus leptocerus Hussey, 1957 and Aneurus politus Say, 1831 in combina-tion with Iralunelus. It is unknown to me why these changes were not incorporated in the Henry and Froeschner’s (1988) catalog. Štys (1974), in erecting Iralunelus, treated Say’s species as Aneurus (Iralunelus) politus, but Froeschner (1988), despite co-authoring the new combinations, oddly noted for Aneu-rus Curtis, 1825: “Four subgenera have been placed within this genus…All species in the area north of Mexico appear to belong to the nominate subgenus.”Distribution: USA: AL, FL, GA, LA, MS, NY.Subfamily ARADINAEAradus cincticornis Bergroth, 1906. – ILLINOIS: Will Co., Crete, 8 April 1906, H. Rumstadt, Aradus proboscideus Walker det. R. F. Hussey 1950, Aradus cincticornis Ber-groth det. D. R. Swanson 2018 [1 ♀] (UMMZ).Notes: Hussey originally identified this specimen as Aradus proboscideus Walker, 1873. However, in A. proboscideus, the disc of the pronotum is more or less flat, not being raised in front or behind the rather shallow transverse sulcus, whereas A. cincticornis (and the Illinoisan specimen) has the trans-verse sulcus deep and the disc distinctly raised in front and behind.The single female on which this record is based has a body length of 8.6 mm. This “breaks” couplet #26 of Parshley’s (1921) key (and Blatchley’s [1926] key based on it), which purports that the body length of A. cincticornis is less than 6.8 mm.Distribution: USA: AL, AR (Taylor and McPherson 1989), IL, MO.Aradus crenatus Say, 1831. – KEN-TUCKY: Jackson Co., 5.4 air mi.

Bowl-ing, det. D. R. Swanson 2012 [1 ♀] (MSUC).Notes: The antennae of this specimen are entirely black, aligning it with Aradus lugubris nigricornis Reuter, 1900. However, Parshley (1921) treated nigricornis as an intergradational color variety with no geo-graphic significance, and I follow the spirit of that treatment.Distribution: USA: AK, AZ, CA, CO, DC, IA (Osborn 1892), ID, IL, MA, ME, MI, MN, MO, MT, NC, ND, NE, NH, NM, NV, NY, OR, PA, RI, UT, WA, WI, WY; Canada: AB, BC, MB, NF, NS, NT, ON, QC, SK, YT.Subfamily MEZIRINAEAphleboderrhis pubescens (Walker, 1873). – MISSOURI: Oregon Co., McCor-mack Lake, Shawnee National Forest, 6 June 1968, E.

Swanson 2013 [1 ♀] (MSUC).Note: A single female from Washington with the following locality data could not be separated from M. sayi: WASHINGTON: Whitman Co., Pullman, 21 September 1919, Phillip Putnam, det. D. R. Swanson 2012 [1 ♀] (UMMZ). However, this represents a large range disjunction, as the nearest re-cords of M. sayi are from Illinois and Texas (Davidová-Vilímová et al. 1996). Thus, it is possible that this female represents an undescribed species. A passive introduction of M. sayi into the Pacific Northwest also remains a possibility. Given the uncertainty, I simply note its existence here, without a formal identification.Distribution: USA: AR (Taylor and McPherson 1989, Davidová-Vilímová et al. 1996), FL, GA, IL (Davidová-Vilímová et al. 1996), IN, LA (Davidová-Vilímová et al. 1996), MS (Davidová-Vilímová et al. 1996), NC (Davidová-Vilímová et al. 1996), SC, TN, TX (Davidová-Vilímová et al. 1996), VA.Neuroctenus simplex (Uhler, 1876). – WISCONSIN: Shawano Co., [no further locality data], 6 September 1950, [no collec-tor], det.
