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 Heteroptera suborder of the Hemiptera order. As Hemiptera, they share 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.

Entomoseius is a genus of mites in the family Otopheidomenidae.
Macrocheraia is a genus of bugs in the family Largidae with a single species, Macrocheraia grandis found mainly in Southeast Asia but extending into parts of South Asia. This was referred to in some older literature under the genus Lohita, a name derived from the Sanskrit word for red.
Pyrrhocoris is a genus of true bugs in the family Pyrrhocoridae, the cotton stainers.
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. The genus currently contains about 25 species, occurring in tropical Africa including Madagascar, South and Southeast Asia, the Malay Archipelago, and New Guinea. Antilochus are brightly coloured, usually red and black, and easily differentiated from other pyrrhocorids by the head being transversely depressed behind the eyes. They are often confused with bugs in the family Lygaeidae, but can be distinguished by the lack of ocelli on the head. Unlike most pyrrhocorids, Antilochus species are predatory, rather than herbivorous.
Melamphaus is an Old World genus of true bugs in the family Pyrrhocoridae, the cotton stainers. 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, but are not known to prey on human flesh or blood.
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.
