Pseudaonidiini is a tribe of armored scale insects. [1] [2]
Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as honeydew on which sooty mold tends to grow. The insects often have a mutualistic relationship with ants, which feed on the honeydew and protect them from predators. There are about 8,000 described species.
The Satyrinae, the satyrines or satyrids, commonly known as the browns, are a subfamily of the Nymphalidae. They were formerly considered a distinct family, Satyridae. This group contains nearly half of the known diversity of brush-footed butterflies. The true number of the Satyrinae species is estimated to exceed 2,400.
The Chamaemyiidae are a small family of acalyptrate flies with less than 200 species described worldwide. The larvae of these small flies are active and predatory and are often used for biological control of aphids, scale insects, and similar pests. Chamaemyiid fossils are poorly represented in amber deposits, but a few examples are known from the Eocene epoch onwards.
The Margarodidae or ground pearls are a family of scale insects within the superfamily Coccoidea. Members of the family include the Polish cochineal and Armenian cochineal and the original ground pearl genus, Margarodes. Beginning in 1880, a number of distinct subfamilies were recognized, with the giant coccids being the first. Although Maskell proposed a new family, many continued to regard the monophlebids as a mere subfamily for many years, and the Margarodidae classification continued to be polyphyletic through the 20th Century. Since then, taking the advice of Koteja several subfamilies and tribes have been elevated into their own families such as Matsucoccidae and Xylococcidae. The pared-down family of Margarodidae is monophyletic.
Melolonthinae is a subfamily of the scarab beetles. It is a very diverse group; distributed over most of the world, it contains over 11,000 species in over 750 genera. Some authors include the scarab subfamilies Euchirinae and Pachypodinae as tribes in the Melolonthinae.
The Phasmatidae are a family of the stick insects. They belong to the superfamily Anareolatae of suborder Verophasmatodea.
The dustywings, Coniopterygidae, are a family of Pterygota of the net-winged insect order (Neuroptera). About 460 living species are known. These tiny insects can usually be determined to genus with a hand lens according to their wing venation, but to distinguish species, examination of the genitals by microscope is usually necessary.
Diaspididae is the largest family of scale insects with over 2650 described species in around 400 genera. As with all scale insects, the female produces a waxy protective scale beneath which it feeds on its host plant. Diaspidid scales are far more substantial than those of most other families, incorporating the exuviae from the first two nymphal instars and sometimes faecal matter and fragments of the host plant. These can be complex and extremely waterproof structures rather resembling a suit of armor. For this reason these insects are commonly referred to as armored scale insects. As it is so robust and firmly attached to the host plant, the scale often persists long after the insect has died.
Coccinellidae is a widespread family of small beetles. They are commonly known as ladybugs in North America and ladybirds in the United Kingdom; "lady" refers to mother Mary. Entomologists use the names ladybird beetles or lady beetles to avoid confusion with true bugs. The more than 6,000 described species have a global distribution and are found in a variety of habitats. They are oval beetles with a domed back and flat underside. They are sexually dimorphic; adult females are larger than males. Many of the species have conspicuous aposematic (warning) colours and patterns, such as red with black spots, that warn potential predators that they taste bad.
Diaspidinae is the largest subfamily of Diaspididae, with 252 genera.
Aspidiotinae is a large subfamily of armored scale insects, with 193 genera.
Aspidiotini is a tribe of armored scale insects.
Odonaspidini is a tribe of armored scale insects.
Parlatoriini is a tribe of armored scale insects. Takagi (2002) indicated that the Parlatoriini appear to be phylogenetically related to the Smilacicola and the Odonaspidini. Takagi went on to say about the tropical east Asian Parlatoriini that, The current classification of their genera may be largely tentative because the adult females are simple-featured and much modified owing to the pupillarial mode of life, and also because the second instar nymphs are generally similar among parlatoriines, whether the adult females are pupillarial or not. Andersen found that separating out pupillarial forms into a separate subtribe, Gymnaspidina, was counterproductive, as being non-dispositive.
Diaspidini is a tribe of armored scale insects.
Lepidosaphidini is a tribe of armored scale insects.
Aspidiotina is a subtribe of armored scale insects.
Fioriniina is a subtribe of armored scale insects.
Rugaspidiotina is an obsolete subtribe of armored scale insects. It was established by Balachowsky in 1949 to accept those Diaspidinae which had rugaspidiotine characteristics as exemplified by genus Rugaspidiotus MacGillivray, species Rugaspidiotus arizonicus, and was moved from the Odonaspidini to the Diaspidini by Borchsenius. It was raised to tribe status as Rugaspidiotini. However, close examination of species assigned to the Rugaspidiotini showed that the rugaspidiotine characteristics convergently evolved in different groups of diaspidids. Rugaspidiotini and Rugaspidiotina are now regarded as obsolete groupings.
Mogoplistidae is a family of scaly crickets within the superfamily Grylloidea. Considered to be monophyletic, a sister taxon to the Gryllidae crickets. This family consists of more than 370 species worldwide; 20 species in 4 genera occur in North America and this family includes the scaly crickets of Europe.
