Organisms were separated from leaf litter, soil, and detritus into ethanol via Berlese funnel, and the aradid was discovered in the subsequent sort and identified as Neuroctenus pseudonymus (Fig. 1), a species previously unknown in Illinois. The specimen bears the following label data : ILLINOIS: Pope Co.: Brasher Cave: entrance: leaf litter, 14 August 2014, coll. SJTaylor, MLNiemiller &amp; SDCinel, Sample Number: 1201, Lot Number Shw 0532, det. D. R. Swanson 2015 [1 male] . The entrance to Brasher Cave lies in a small, shallow, thinly-wooded sinkhole (Fig. 10) in an upland deciduous (oak) forest. The forested setting results in copious accumulations of leaf litter in and around the cave entrance. The specimen, now dried and point-mounted, has been vouchered in the Illinois Natural History Survey Insect Collection (INHS Insect Collection 809,670).</p><p>A search for corroborative material in that collection revealed three additional specimens with the following label data: ILLINOIS: [Calhoun Co.], Hardin, 5–9 June 1932, coll. H. L. Dozier, det. D. R. Swanson 2016, INHS Insect Collection 777,271 [1 female] ; [Champaign Co.], Urbana, University Woods, from soil cover in woods, 15 Oct. 1933, M. D. Farrar, det. P. D. Ashlock 1938, det. D. R. Swanson 2016, INHS Insect Collection 777,274; Union Co., Pine Hills, under flat stone near swamp, 20 March 1988, S. Taylor, det. S. Taylor 1988, INHS Insect Collection 775,584 [1 female, figured].</p><p>Sparsely mentioned in the literature, Ne. pseudonymus is easily recognized among the six Nearctic species of the genus by the ovate form of the body and the folds present on the seventh tergite. Heidemann (1904) reported this species from under the bark of fallen chestnut ( Castanea sp.). McClure (1932) documented prenatal care in this species. Froeschner (1988a) recorded the species from Washington, D.C. , Indiana, North Carolina, Ohio, Tennessee, and Texas, and Kormilev (1982) added Maryland and Virginia . More recently, Taylor &amp; Gil (2009) recorded Ne. pseudonymus from Louisiana . The current known distribution of the species north of Mexico is summarized in Fig. 15.</p><p>Also found in the INHS was a single adult female of Nannium pusio . The specimen (Fig. 2) bears the following label data: ILLINOIS: [St. Clair Co.], Edgemont, debr. in tree, 16 September 1943, W. E. Snow, det. D. R. Swanson 2015 , INHS Insect Collection 775,583 [1 female] (INHS). Although not "freshly caught", the specimen is conveniently reported here as a new state record to provide a more complete picture of the Mezirinae of Illinois . Nannium pusio is easily separated from other mezirines by the small size and trisinuate posterior margin of the pronotum. Until now, it has only been recorded from the type locality in Ohio ( Froeschner 1988a).</p><p>Aradids, as compared to other heteropterans, are generally encountered less frequently, being well-suited to their cryptic, subcorticulous habitat. Thus, it is unsurprising to add new aradids to the state faunal list. Indeed, based on adjacent state records, seven more species may yet be found in Illinois (Froeschner 1988a). Yet, the decline of old growth forests over the last century (Parker 1989) may have led to the extirpation of some species previously distributed in the state.</p><p>With the addition of Neuroctenus pseudonymus and Nannium pusio, six species of mezirine flat bugs are known from Illinois; the other four species are: Mezira granulata (Say, 1831); Mezira lobata (Say, 1831); Mezira sayi Kormilev, 1982; and Neuroctenus simplex (Uhler, 1876) . The following key was constructed using Blatchley (1926), Torre-Bueno (1939), Kormilev (1982), and Davidová-Vilímová et al. (1996). An additional species of Mezirinae, Neuroctenus elongatus Osborn, 1903, may yet be found in the state, given its presence in Indiana and Ohio (Froeschner 1988a).</p></div>	https://treatment.plazi.org/id/BB2C183C0C43FFA6FF7F54B155ED47D5	Public Domain	No known copyright restrictions apply.

This specimen was taken in the shrubby transition zone between the prairie vegetation and the wooded sinkhole. The female has been vouchered in the Illinois Natural History Survey Insect Collection (INHS Insect Collection 780,163), and the male has been retained in the first author's collection (DRS). A search for corroborative material in INHS revealed several additional specimens: ILLINOIS: [Clark Co.], Parker, sweepings, 18 May 1908, [no collector], INHS Insect Collection 569,605 [1 male]; [Jackson Co.], Makanda, Giant City [ State] Park, 10 May 1932, H.

All of the supplemental specimens were identified as Arhyssus bohemonii [sic] by Harris in 1945.</p><p>In the eastern states, A. nigristernum resembles many other rhopalines, generally requiring examination of the pronotum and metapleuron under a microscope to confirm the genus. However, dark individuals (such as the pair caught here) are distinctive among eastern species of Arhyssus . In past literature, this species was often listed under a junior synonym, Corizus bohemani Signoret, 1859 . Henry (1988) recorded A. nigristernum from Arkansas , Connecticut, Florida, Indiana, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Mississippi, Missouri, North Carolina, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Tennessee, Texas, Virginia, and West Virginia, as well as Washington, D.C., Ontario, and Quebec . Parshley (1917) included New Hampshire . Chopra's (1968) distribution map included dots for several specimens from Illinois (as well as Alabama, Georgia, Oklahoma, and South Carolina), although these states were not listed under "Material Examined", and we are unaware of any other literature records for A. nigristernum in these states. The current known distribution of the species north of Mexico is summarized in Fig. 20.</p><p>The unreported status of Illinoisan records for this species was overlooked in Heads et al. (2015), and there are a few reasons that could account for this species going previously unnoticed. It appears to be less common than Arhyssus lateralis (Say, 1825), and pale individuals of A. nigristernum could easily be confounded with the former, as well as other rhopalines. Furthermore, A. nigristernum is not considered economically important (inferred from absence in Schaefer &amp; Kotulski 2000).</p><p>Two other new state records are here conveniently reported, based on material housed in the INHS, in order to more fully flesh-out the rhopalid diversity of Illinois. Furthermore, both species can be considered beneficial in that they feed on plants often considered pests (Schaefer &amp; Kotulski 2000).</p><p>Several specimens, including a large series, of Aufeius impressicollis (Fig. 8) were discovered in the collection. They bear the following label data: ILLINOIS: [Champaign Co.], Champaign, 31 October 1906, Hart &amp; Hood, det. Harris 1945, INHS Insect Collection 568,581–568,588 &amp; 568,601–568,607 [7 males, 6 females]; Champaign Co., Urbana , 13 Nov. 1915, [no collector], det. Harris 1945, INHS Insect Collection 568,595 [1 male]. Henry (1988) recorded A. impressicollis from Arizona, Arkansas, California, Colorado, Idaho, Indiana, Iowa, Kansas, Maryland, Missouri, Nebraska, New Mexico, Ohio, South Dakota, Texas, Utah, and Washington . Wheeler (1988) added South Carolina, and Wheeler (2002) added Georgia, North Carolina, and Oklahoma . The current known distribution of the species north of Mexico is summarized in Fig. 21. Given this range, it is unsurprising to find this species in Illinois. Aufeius impressicollis feeds on various Amaranthaceae, including smooth pigweed ( Amaranthus hybridus L.) (Wheeler 1984, 1988, 2002; Schaefer &amp; Kotulski 2000).</p><p>A single specimen of Niesthrea louisianica (Fig. 9) also was present in the INHS. The specimen bears the following label: ILLINOIS: S . Illinois [no further data], Andreas Bolter Collection, det. D. R. Swanson 2016, INHS Insect Collection 754,415 [1 female] . However, the presence of N. louisianica in Illinois is corroborated by an individual photographed in Fairfield, Wayne County, Illinois on 3 November 2005 and posted to BugGuide.net (http://bugguide.net/node/view/36397). Henry (1988) recorded this species from Alabama, Arizona, Arkansas, Florida, Georgia, Iowa, Kansas, Louisiana, Maryland, Mississippi, Missouri, New Jersey, New Mexico, New York, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, Utah, and Virginia. The current known distribution of the species north of Mexico is summarized in Fig. 22. Finding this species in Illinois was not surprising, particularly in the southern part of the state. Niesthrea louisianica is known to feed on velvetleaf ( Abutilon theophrasti Medikus), which plant can be pestiferous in monocultures of corn, soybean, cotton, and sorghum (Schaefer &amp; Kotulski 2000).</p><p>With the addition of A. nigristernum, A. impressicollis, and N. louisianica, eight species of scentless bugs are known from Illinois; the other five species are: Arhyssus lateralis (Say, 1825); Boisea trivittata (Say, 1825); Harmostes fraterculus (Say, 1831); Harmostes reflexulus (Say, 1831); and Jadera haematoloma (Herrich- Schaeffer, 1847). The following key was constructed using Hoebeke &amp; Wheeler (1982) and Swanson (2011). Three additional species, i.e., Brachycarenus trigrinus (Schilling, 1829); Liorhyssus hyalinus (Fabricius, 1794); Stictopleurus punctiventris (Dallas, 1852), may yet be found in Illinois, given their presence in other surrounding Midwest states (Henry 1988).</p></div>	https://treatment.plazi.org/id/BB2C183C0C4BFFAFFF7F511455B146D9	Public Domain	No known copyright restrictions apply.
