Hysteropterinae
A subfamily of planthopper bugs in the family Issidae, containing approximately 59 genera distributed across Europe, Africa, and Asia. The group is characterized by its type genus Hysteropterum. One member species, Agalmatium bilobum, has established as an invasive population in California, United States.
Hysteropterini
Hysteropterini is a tribe of planthoppers within the family Issidae, subfamily Hysteropterinae. Members of this tribe are characterized by their compact body form and reduced wings, adaptations associated with a ground-dwelling or low-vegetation lifestyle. The tribe was established by Melichar in 1906 and contains multiple genera distributed primarily in the Palearctic region. These insects are part of the diverse fulgoromorph fauna but are less frequently encountered than their more volant relatives.
Issinae
Issinae is a subfamily of planthoppers within the family Issidae (Hemiptera: Fulgoroidea). The group contains multiple tribes including the recently erected Picumnini and subtribe Duroidina within Parahiraciini. Taxonomic revisions continue to clarify relationships within this subfamily, particularly regarding New World taxa. The subfamily is characterized by specific morphological features including wing venation and body form typical of the Issidae family.
Kathleenum
Kathleenum is a genus of planthoppers in the family Issidae, described by Gnezdilov in 2004. It belongs to the tribe Thioniini and subtribe Thioniina within the subfamily Issinae. The genus is part of the diverse fulgoroid radiation of Hemiptera, characterized by their distinctive body forms and reduced wings in many species. As a relatively recently described genus, its species-level diversity and biology remain incompletely documented.
Kathleenum cornutum cornutum
Kathleenum cornutum cornutum is a subspecies of planthopper in the family Issidae, described by Melichar in 1906. It belongs to the infraorder Fulgoromorpha, a group of hemipteran insects commonly known as planthoppers. The specific epithet 'cornutum' (Latin for 'horned') suggests the presence of horn-like projections, a trait found in various Issidae species. This subspecies is part of the Neotropical issid fauna, though detailed biological studies remain limited.
Kathleenum cornutum utahnum
Kathleenum cornutum utahnum is a subspecies of planthopper in the family Issidae, originally described by Ball in 1935. It belongs to a group of small, often cryptic insects commonly known as issid planthoppers or twig hoppers. The subspecies epithet 'utahnum' indicates a geographic association with Utah, distinguishing it from the nominate subspecies. Like other issids, it likely inhabits grassland or shrubland environments where it feeds on plant phloem sap.
Paralixes
Paralixes is a genus of planthoppers in the family Issidae, described by Caldwell in 1945. It belongs to the tribe Thioniini within the subfamily Issinae. Members of this genus are small, often compact-bodied insects adapted to life on host plants. The genus is poorly documented in scientific literature, with limited species-level descriptions and biological data available.
Paralixes scutatus
Paralixes scutatus is a species of planthopper in the family Issidae, first described by Walker in 1858. It belongs to the tribe Thioniini within the subfamily Issinae. The species has been recorded from the southwestern United States and parts of Central America. Like other Issidae, it is a member of the Fulgoroidea superfamily, characterized by their distinctive body shape and reduced wings in many species.
Picumna
Picumna is a genus of planthoppers in the family Issidae, characterized by four spines on the hind tibia—a diagnostic feature distinguishing it from similar genera. The genus was erected by Stål in 1864 and is now placed in the tribe Picumnini. Species occur in the Southwestern United States and Central America.
Picumna maculata
Picumna maculata is a species of planthopper in the family Issidae, described by Melichar in 1906. It belongs to the tribe Thioniini within the subfamily Issinae. Like other issid planthoppers, it is characterized by a compact body form and wings held in a tent-like position over the body. The specific epithet 'maculata' suggests a spotted or maculate color pattern, though detailed descriptions of adult morphology remain limited in available sources.
Thionia elliptica
Thionia elliptica is a species of issid planthopper in the family Issidae, first described by Germar in 1830. It belongs to the order Hemiptera, suborder Auchenorrhyncha. The species has been recorded from multiple states in the southeastern and mid-Atlantic United States.
Thionia omani
Thionia omani is a species of planthopper in the family Issidae, first described by Doering in 1938. It belongs to the superfamily Fulgoroidea, a diverse group of sap-feeding insects commonly known as planthoppers. The specific epithet "omani" suggests a connection to Oman, though the precise type locality and original collection details require verification from the original description. As a member of Issidae, it possesses the characteristic body form of this family, with a somewhat flattened, often compact body and wings that may be reduced or fully developed.
Thioniini
Thioniini is a tribe of planthoppers within the family Issidae, established by Melichar in 1906. Members are small, often cryptically colored insects with reduced wings or brachypterous forms common in the group. The tribe is primarily distributed in the Palearctic region, with notable diversity in the Mediterranean basin and parts of Asia. Thioniini species are frequently associated with rocky or arid habitats and are known for their jumping locomotion typical of fulgoromorphans.
