Species in Aradidae (125)

Aneurus avenius
Aneurus avenius
Length 4 to 5 mm. Unlike Aradus species, the wings of Aneurus flatbugs are completely membranous with the exception of the base. The two species are very similar. In females, the tip of the abdomen (genital segment) is flattened in A. avenius and bil

Aradus acutus
Aradus acutus
Identification: silvery spots on abdominal tergites along the connexivum are diagnostic

Aradus aequalis
Aradus aequalis
Identification: The relatively short antennomere 2 and almost straight anterolateral and posterolateral margins of the pronotum are characteristic

Aradus antennalis
Aradus antennalis
Identification: Separated from A. kormilevi by the bicolorous third antennal segment (apical half pale yellow), whereas this segment is unicolorous in A. kormilevi . Furthermore, brachypterous females of A. antennalis have a distinct narrow membrane

Aradus approximatus
Aradus approximatus
Identification: In the East, identified by the long second antennal segment (more than 3x length of third) with the abruptly enlarged apex. The large size and overall pale coloration also may aid in separating A. approximatus from several other spec
Aradus brevicornis 0
Aradus brevicornis
Identification: antenna slightly longer than head width • females brachypterous • imaged in

Aradus carolinensis
Aradus carolinensis
Identification: type specimen one of only 3 or 4 eastern spp. described after publication of

Aradus cf-oviventris
Aradus cf-oviventris
Identification: based on description, Aradus oviventris Kormilev 1966 (AZ; nr basalis ) is similar but testaceous with darker parts

Aradus crenatus
Aradus crenatus
Identification: This common species is recognizable by its large size, peculiar antennal structure, and strongly crenate abdomen

Aradus depictus
Aradus depictus
Identification: coloration unique among nearctic congeners

Aradus depressus
Aradus depressus
Length 5 to 6 mm. Unlike Aneurus species, the wing membrane in Aradus flatbugs does not extend below the apex of the scutellum. A. depressus is distinguished by the pale shoulders, and the 2nd and 3rd antennal segments are similar in length. Detailed

Aradus gracilis
Aradus gracilis
Identification: readily id'd by coloration, expanded pronotum, and slender scutellum

Aradus inornatus
Aradus inornatus
Identification: Among those eastern species with the antennae thinner than the profemur and a serrate lateral pronotal margin, this species is diagnosed by the clavate (gradually enlarged from base to apex) second antennomere being greater than three

Aradus laeviusculus
Aradus laeviusculus
Aradus laeviusculus (Aradus laeviusculus) is a species in the family Aradidae, commonly known as flat bugs, belonging to the order Hemiptera (True Bugs, Cicadas, Hoppers, Aphids and Allies). It is classified within the subfamily Aradinae, suborder He

Identification: very similar to the eastern A. crenatus in habitus & antennae; photos in

Aradus ovatus
Aradus ovatus
i found a female that matches the orig. description (also based on a single female) of this very distinctive mystery bug; not sure if any other specimens are known, will ask around

Aradus paganicus
Aradus paganicus
Identification: closely related to A. acutus , can be separated by the duller general coloration and the bulged median carinae of the pronotum

Aradus pictellus 0
Aradus pictellus
Identification: adult habitus ( 3 ) • photo gallery ( 4 )

Aradus quadrilineatus
Aradus quadrilineatus
Identification: The strongly thickened antennomere 3 and the strongly expanded median portion of the pronotum are diagnostic

Aradus robustus
Aradus robustus
one of the most commonly collected Aradus in NA ( 3 )

Aradus similis
Aradus similis
Identification: 3rd antennal segment pale yellow except fuscous base In the relatively thick median process of the head and the relatively short antennae resembles A. parvicornis ; however, in A. similis the median process of the head does not reach

Aradus uniformis
Aradus uniformis
Identification: note pale third antennomere and smooth pronotal margin "In the eastern and central species with antennae not distinctly thicker than the profemur, entire (not serrate) pronotal margin, and more or less dilated bases of the hemelytra,

Iralunelus politus
Iralunelus politus
Identification: One of four [aneurine] species in our area with a conspicuous anteromedial callosity on the scutellum (others are leptocerus , minutus , and pygmaeus ). Of these four, two have the second antennal segment longer than the scape and are

Mezira emarginata
Mezira emarginata
Identification: Separated from M. lobata by the less explanate anterolateral pronotal angles, more shallow transverse pronotal sulcus, and more evenly granulate posterior pronotal lobe.

Mezira lobata
Mezira lobata
Identification: Separated from M. emarginata in having large explanate anterolateral corners of the pronotum, a deep transverse pronotal sulcus, and more rugose elevations to the posterior pronotal lobe.

Nannium pusio
Nannium pusio
found a couple of these sensational bugs in TAMUIC, very distinctive

Neuroctenus elongatus
Neuroctenus elongatus
Identification: The large paratergites next to the simple ninth tergite in the females will separate this species from the other Neuroctenus species in our area

Neuroctenus pseudonymus
Neuroctenus pseudonymus
Identification: Recognized by the transverse fold on the seventh tergite of the male.

Neuroctenus simplex
Neuroctenus simplex
Identification: paratergites subquadrate, tergite IX notched
Neuroctenus unistellatus 0
Neuroctenus unistellatus
Identification: Vásárhelyi did not menion the large eighth paratergites in the male, unique among congeners in our area described from a series collected in Austin, TX; i think i have specimens that may represent this from. =v=

Quilnus heidemanni
Quilnus heidemanni
Identification: One of three species in Quilnus with the antennae not much thicker than profemur. Quilnus usingeri is macropterous, whereas Q. heidemanni is brachypterous. A. oregonicus , which was described in the subgenus Quilnus and stated to be c
