Roscius is an Afrotropical genus of true bugs in the family Pyrrhocoridae, the cotton stainers. [1] They are often confused with bugs in the family Lygaeidae, such as the genus Oncopeltus , but can be distinguished by the lack of ocelli on the head.
The Pentatomoidea are a superfamily of insects in the suborder Heteroptera of the order Hemiptera. As hemipterans, they possess a common arrangement of sucking mouthparts. The roughly 7000 species under Pentatomoidea are divided into 21 families. Among these are the stink bugs and shield bugs, jewel bugs, giant shield bugs, and burrower bugs.
Pyrrhocoridae is a family of insects with more than 300 species world-wide. Many are red coloured and are known as red bugs and some species are called cotton stainers because their feeding activities leave an indelible yellow-brownish stain on cotton crops. A common species in parts of Europe is the firebug, and its genus name Pyrrhocoris and the family name are derived from the Greek roots for fire "pyrrho-" and bug "coris". Members of this family are often confused with, but can be quickly separated from, Lygaeidae by the lack of ocelli on the top of the head.
The superfamily Membracoidea of sap-sucking true-bugs includes two of the largest families within what used to be called the "Homoptera": the leafhoppers (Cicadellidae) and the treehoppers (Membracidae). The other families in this group are quite small, and have, at various points, generally been included as members within other families, though they are all presently considered to be valid, monophyletic groups. The relict family Myerslopiidae is restricted to New Zealand and South America while the Melizoderidae consist of two genera restricted to South America. The great diversity of Neotropical taxa suggests that the group originated in that region.
Roscius may refer to:
Rhopalidae, or scentless plant bugs, are a family of true bugs. In older literature, the family is sometimes called "Corizidae". They differ from the related coreids in lacking well-developed scent glands. They are usually light-colored and smaller than the coreids. Some are very similar to the orsilline lygaeids, but can be distinguished by the numerous veins in the membrane of the hemelytra. They live principally on weeds, but a few are arboreal. All are plant feeders. The type genus for the family is: Rhopalus. Currently 30 genera and over 240 species of rhopalids are known. The oldest fossil rhopalids described are from the Middle Jurassic of Inner Mongolia, discovered from the Haifanggou Formation. They are not considered economically important with a few species being pests of ornamental trees.
Entomoseius is a genus of mites in the family Otopheidomenidae.
Pyrrhocoris is a genus of true bugs in the family Pyrrhocoridae, the cotton stainers. Records of occurrence are mainly in the Palaearctic realm, with some from North America and East Asia.
Dysdercus is a widespread genus of true bugs in the family Pyrrhocoridae; a number of species attacking cotton bolls may be called "cotton stainers".
Antilochus is an Old World genus of true bugs in the family Pyrrhocoridae, erected by Carl Stål in 1863. Species in this genus occurs in tropical Africa including Madagascar, South and Southeast Asia, the Malay Archipelago, and New Guinea.
Melamphaus is an Old World genus of true bugs in the family Pyrrhocoridae, mostly found in Asia. They are often confused with bugs in the family Lygaeidae, but can be distinguished by the lack of ocelli on the head.
Probergrothius is an Old World genus of true bugs in the family Pyrrhocoridae. The genus was previously referred to as Odontopus, but that name was already in use for a genus of weevils, and was therefore replaced by Probergrothius in 1904. Members of this genus are reported to feed mainly on members of the plant order Malvales, including Sterculia, baobab (Adansonia), and kapok, but will feed on others as well. The welwitschia bug, Probergrothius angolensis, feeds on Welwitschia seeds, which is a gymnosperm, unlike the Malvales, which are angiosperms.
Antilochus coquebertii is an Old World species of true bug in the family Pyrrhocoridae, occurring in South and Southeast Asia. It is brightly coloured, red and black, and is a beneficial predator on other pyrrhocorids, especially the genus Dysdercus, which are crop pests. They are often confused with bugs in the family Lygaeidae, but can be distinguished by the lack of ocelli on the head, and they can be easily distinguished from Dysdercus by the lack of white stripes on the body. They are known to be cannibalistic in nature.
Scantius aegyptius, the Mediterranean red bug, is a species of red bug in the family Pyrrhocoridae, that is a pest of plant species in the family Malvaceae.
Scantius is a genus of mostly African and European bugs in the family Pyrrhocoridae. There are at least two described species in Scantius.
Berytinus is a genus of stilt bugs in the family Berytidae. There are about 12 described species in Berytinus.
Jalysus is a genus of stilt bugs in the family Berytidae. There are about 12 described species in Jalysus.
Hoplinus is a genus of stilt bugs in the family Berytidae. There are about six described species in Hoplinus.
Arhaphe is a genus of bordered plant bugs in the family Largidae. There are 26 described species in Arhaphe. The genus is one of a small number of hemipterans known to possess a sound-producing stridulitrum, in which the hind femur is rubbed against the costal margin of the forewings.
Xyonysius is a genus of seed bugs in the family Lygaeidae. There are about eight described species in Xyonysius.
Anochrostomus is a genus of seed bugs in the family Lygaeidae. There are at least two described species in Anochrostomus.
