| Graphopsocus cruciatus (Linnaeus, 1768) | |
Graphopsocus cruciatus is a species of Psocoptera from Stenopsocidae family. The species was introduced to the West from Asia or Europe in 1930. [1] [2]
The species have five dark marks on the first half of the wing and a light "F" like mark on the second half. [1]
Psocoptera are an order of insects that are commonly known as booklice, barklice or barkflies. They first appeared in the Permian period, 295–248 million years ago. They are often regarded as the most primitive of the hemipteroids. Their name originates from the Greek word ψῶχος, psokhos meaning gnawed or rubbed and πτερά, ptera meaning wings. There are more than 5,500 species in 41 families in three suborders. Many of these species have only been described in recent years.
The Mymarommatidae, sometimes referred to as False fairy wasps. are a very small family of microscopic hymenopteran insects. Only about half of the known species are living taxa, but they are known from all parts of the world. Undoubtedly, many more await discovery, as they are easily overlooked and difficult to study due to their extremely small size.
Psocomorpha is a suborder of barklice, booklice, and parasitic lice in the order Psocoptera. There are more than 20 families and 5,300 described species in Psocomorpha.
Amphientomidae is a family of Psocoptera belonging to the suborder Troctomorpha. The presence of scales on their wings gives them a superficial resemblance to the unrelated family Lepidopsocidae and both families can pass for microlepidoptera to the untrained eye. The family comprises 100 species arranged in twenty genera.
Amphipsocidae is a family of hairy-winged barklice in the order Psocoptera. Most species are 3.0-4.5 mm long and have many setae (hairs) on the veins and margin of the forewing. The main veins of the forewing are usually lined with two rows of setae. Like the other members of the infra-order Caeciliusetae, they have a broad, flat labrum, with well defined edges.
Compsocidae is a family of Psocoptera belonging to the suborder Troctomorpha. The family comprises two extant species in two genera, both found in Mesoamerica. Compsocus elegans is found in Mexico and Central America, while Electrentomopsis variegata is found in Mexico. The antennae of each species have 13 or 14 segments. Two extinct genera, Burmacompsocus and Paraelectrentomopsis are known from the Cenomanian aged Burmese amber of Myanmar.
Liposcelididae is a family of booklice (Psocoptera) belonging to the suborder Troctomorpha. Members of this family are small and flattened, and often wingless.
Peripsocidae is a family of Psocoptera belonging to the suborder Psocomorpha. Members of the family are characterised by their absence of an areola postica in their wings. Many of the recently described genera are closely allied to Peripsocus. The family includes more than 300 species.
Ectopsocidae is a family of Psocoptera belonging to the suborder Psocomorpha. Members of the family are characterised by their absence of an areola postica in their wings, like in the family Peripsocidae. The family includes fewer than 200 species, most of them in the genus Ectopsocus.
Psilopsocidae is a family of Psocoptera belonging to the infraorder Psocetae. Members of the family have a free areola postica and mottled wings. It is the only psocopteran family with records of wood-boring species. The family comprises one genus and seven species.
Mesopsocidae is a family of Psocoptera belonging to the suborder Psocomorpha. Members of the family are characterised by their free areola postica. The family includes more than 70 species.
Homilopscocidea is an infraorder of Psocoptera. It is probably a paraphyletic group, still in use for lack of a better solution. There are about 7 families and more than 1,200 described species in Homilopsocidea.
Stenopsocidae is a family of Psocoptera belonging to the suborder Psocomorpha, in the infraorder Caeciliusetae. Member of this family have an areola postica connected to the M vein by a crossvein. The family is composed of about 100 species.
Psocodea is a taxonomic group of insects comprising the bark lice, book lice and true lice. It was formerly considered a superorder, but is now generally considered by entomologists as an order. Despite the greatly differing appearance of lice, they are believed to have evolved from within the former order "Psocoptera", which contained the bark lice and book lice. Psocodea contains around 11,000 species, divided among three suborders.
Ectopsocus briggsi is a species of Psocoptera from Ectopsocidae family that can be found in Great Britain and Ireland. The species are brownish-orange coloured.
Ectopsocus petersi is a species of Psocoptera from Stenopsocidae family that can be found in Great Britain and Ireland. The species are brownish-orange coloured and is similar to Ectopsocus briggsi.
Trichadenotecnum is a genus of insects in the order Psocoptera, the booklice, barklice, and bookflies. It is one of the largest genera, including over 200 described species.
Lepidopsocidae are an insect family of bark lice (Psocoptera) belonging to the suborder Trogiomorpha. Colloquially, Lepidopsocidae are referred to as the Scaly-winged Barklice. There are more than 220 species described worldwide. Phylogenetic analysis of relationships between families in Trogiomorpha, based on partial sequences of the nuclear 18S rDNA, mitochondrial 16S rDNA, and Histone 3 genes, propose that Lepidopsocidae is monophyletic, meaning that the taxa within share a common ancestor. This is supported morphologically by the presence of scales and setae covering the body and forewings of Lepodopsocids. Sister families of Lepidoposcidae include Trogiidae and Psoquillidae.
Liposcelis is a genus of insects in the order Psocoptera, the booklice and barklice. There are about 126 species. Many species are associated with human habitation and several are well known as pests of stored products. The genus is distributed nearly worldwide.
Epipsocetae is an infraorder of psocids in the order Psocoptera. There are about 5 families and more than 480 described species in Epipsocetae.
