Taylor and J. E. McPherson' ABSTRACT Eight aradid species are reported for the first time from Arkansas including Aneurus pygmaeus, Aradus cillcticornis, Aradus crenatus, Qui/nus niger, Mezira granulata, Mezira lobata, Mezira sayi, and Neuroctenus simplex. The presence of Aradus acufus, Aradus falleni, and Aradus robustus in Arkansas is confirmed. Few records have been published on Arkansas Aradidae. Parshley (1922) reported Aradus acutus Say and Aradusfalleni Still from the state and Drake and Kormilev (1958) extended the range of Acaricoris ignotus Harris and Drake from Louisiana, Mississippi, and Georgia to include Arkansas. Leschen and Taylor (1987) found Aradus robustus Uhler in Arkansas and provided information on its biology. Because information on these bugs in Arkansas is so limited, a faunal survey was conducted from 1984 to 1987. A total of 1,125 specimens of 11 species was collected, most by hand picking. For the listing of these specimens below, data were collected by SJT unless stated otherwise. Specimens collected by SJT were found under bark of dead hardwoods unless stated otherwise. Collections from under bark of dead Quercus sp. are indicated by UBDQ. Numbers of adult males and females and additional host plant data are indicated in parentheses following each locality. Cadron Settlement Park, Quail Restoration Area, and Bell Slough Wildlife Management Area, the most frequent collection localities, are indicated by CSP, QRA, and BSWMA, respectively. Immature stages were not included in counts since they cannot be reliably identified; however, immatures often outnumbered adults at various sites. The sequence of aradid taxa follows Kormilev and Froeschner (1987). Specimens are deposited in the SJT collection and the Southern Illinois University Entomology Collection (SIUEC). ANEURINAE Aneurus pygmaeus Kormilev is known from Florida, Georgia, Texas, and California (Picchi 1977), Here we rcport material representing a northern range extension for the species and the first record of Aneurus in Arkansas.

DISCUSSION Zoogeographic affmities of aradids at the generic level havc been discussed by Slater (1974) and Kormilev and Froeschner (1987). Of the five Arkansas genera reported here (i.e., Quilnus, Aneurus, Aradus, Mezira, and Neuroctenus). Quilnus is Holarctic in distribution, whereas the other genera occur worldwide. The Arkansas species of Quilnus, Aneurus and Aradus have affinities with Pale arctic aradids, and those of Mezim and Neuroctenus are more closely related to the fauna of the Neotropics. Acaricoris, which is known from Arkansas (Drake and Kormilev 1958) but was not collected in our study, is primarily a Neotropical genus which includes two species in the southern United States and four Neotropical species. Slater (1974) reported that the Connecticut aradid fauna is dominated by species associated with the Palearctic region. We found that while the Palearctic element of the Arkansas fauna (Quilnus, Aneurus, Aradus) contains more species, the Neotropical element (Le., Mezira, Neuroctenus) appears to contain more individuals. The distributions of North American species of Aradidae are not well known, possibly because the cryptic coloration and secretive habits of these bugs necessitate specific collecting techniques not usually employed by the general collector. The fact that this paper includes several new state records and yet is based upon collecting done primarily in only a few counties of Arkansas emphasizes how poorly known the distributions of flat bugs are. A general survey of Arkansas Aradidae would probably result in the addition of several more species to the state's known fauna. ACKNOWLEDGMENTS We thank Richard C.

STATE RECORDS AND CONFIRMATIONS OF ARKANSAS FLAT 

BUGS (HETEROPTERA: ARADIDAE) 

Steven J. Taylor and J. E. McPherson' 
ABSTRACT 
Eight aradid species are reported for the first time from Arkansas including Aneurus 
pygmaeus, Aradus cillcticornis, Aradus crenatus, Qui/nus niger, Mezira granulata, 
Mezira lobata, Mezira sayi, and Neuroctenus simplex. The presence of Aradus acufus, 
Aradus falleni, and Aradus robustus in Arkansas is confirmed. 
Few records have been published on Arkansas Aradidae. Parshley (1922) reported 
Aradus acutus Say and Aradusfalleni Still from the state and Drake and Kormilev (1958) 
extended the range of Acaricoris ignotus Harris and Drake from Louisiana, Mississippi, 
and Georgia to include Arkansas. Leschen and Taylor (1987) found Aradus robustus 
Uhler in Arkansas and provided information on its biology. 
Because information on these bugs in Arkansas is so limited, a faunal survey was 
conducted from 1984 to 1987. A total of 1,125 specimens of 11 species was collected, 
most by hand picking. For the listing of these specimens below, data were collected by 
SJT unless stated otherwise. Specimens collected by SJT were found under bark of dead 
hardwoods unless stated otherwise. Collections from under bark of dead Quercus sp. are 
indicated by UBDQ. Numbers of adult males and females and additional host plant data 
are indicated in parentheses following each locality. Cadron Settlement Park, Quail 
Restoration Area, and Bell Slough Wildlife Management Area, the most frequent 
collection localities, are indicated by CSP, QRA, and BSWMA, respectively. Immature 
stages were not included in counts since they cannot be reliably identified; however, 
immatures often outnumbered adults at various sites. The sequence of aradid taxa follows 
Kormilev and Froeschner (1987). Specimens are deposited in the SJT collection and the 
Southern Illinois University Entomology Collection (SIUEC). 
ANEURINAE 
Aneurus pygmaeus Kormilev is known from Florida, Georgia, Texas, and California 
(Picchi 1977), Here we rcport material representing a northern range extension for the 
species and the first record of Aneurus in Arkansas.

Aradus crenatus Say occurs throughout much of eastern North America from Qucbcc 
and Ontario south to Georgia, Alabama, Illinois, and Mexico (Blatchley 1926). It was 
formerly thought to be a Holarctic species, but the European taxon (Aradus conspicuus 
Herrich-Schaeffer) is now considered a separate species (Heiss 1980). A. crenatus has not 
previously been reported from Arkansas.

Aradus falleni Stal is the most widespread of the New World Aradus species, being 
found from Brazil north to British Columbia and New York (Parshley 1922). Parshley 
(1922) reported this species from Arkansas, and its presence in Arkansas is here 
confirmed.

Aradus robustus Uhler is widely distributed from the Northwest Territories, Nebraska,

was recently described (Kormilev 1982), and, since these two are both common, 
closely related, and appear to have broadly overlapping ranges, distributions of both 
species need to be confirmed. Kormilev (1982) reported M. granulata from Maryland and 
North Carolina. It has not previously been reported from Arkansas.

DISCUSSION 
Zoogeographic affmities of aradids at the generic level havc been discussed by Slater 
(1974) and Kormilev and Froeschner (1987). Of the five Arkansas genera reported here 
(i.e., Quilnus, Aneurus, Aradus, Mezira, and Neuroctenus). Quilnus is Holarctic in 
distribution, whereas the other genera occur worldwide. The Arkansas species of Quilnus, 
Aneurus and Aradus have affinities with Pale arctic aradids, and those of Mezim and 
Neuroctenus are more closely related to the fauna of the Neotropics. Acaricoris, which is 
known from Arkansas (Drake and Kormilev 1958) but was not collected in our study, is 
primarily a Neotropical genus which includes two species in the southern United States 
and four Neotropical species. 
Slater (1974) reported that the Connecticut aradid fauna is dominated by species 
associated with the Palearctic region. We found that while the Palearctic element of the 
Arkansas fauna (Quilnus, Aneurus, Aradus) contains more species, the Neotropical 
element (Le., Mezira, Neuroctenus) appears to contain more individuals. 
The distributions of North American species of Aradidae are not well known, possibly 
because the cryptic coloration and secretive habits of these bugs necessitate specific 
collecting techniques not usually employed by the general collector. The fact that this 
paper includes several new state records and yet is based upon collecting done primarily 
in only a few counties of Arkansas emphasizes how poorly known the distributions of flat 
bugs are. A general survey of Arkansas Aradidae would probably result in the addition of 
several more species to the state's known fauna.
