Psocodea

Mecampsis

Belongs within: Psocinae. Mecampsis is a genus of psocid barklice found in Asia and South America that has veins Rs and M in the fore wing joined by a cross-vein (Li 2002). Characters (Li 2002): Long wings; medium-sized, body-wing length 4–7 mm. Length of distal segment of maxillary palp more than three times width; antennae shorter than fore… Continue reading Mecampsis

Homilopsocidea

Belongs within: Psocomorpha.Contains: Elipsocidae, Lachesilloidea, Pseudocaecilioidea, Peripsocoidea. The Homilopsocidea are a clade of bark-lice supported by two synapomorphies: the presence of an egg-guide extending from the dorsodistal margin of the female subgenital plate, and dorsal swelling of the dorsal valve of the gonapophyses (Yoshizawa 2002). The Lesneiidae are a family of uncertain affinities within this… Continue reading Homilopsocidea

Siniamphipsocus

Belongs within: Caeciliusetae. Siniamphipsocus is a genus of barklice found in northeastern Asia (Li 2002). Hairy-winged barklice Published 9 September 2017 For my next semi-random post, I drew Siniamphipsocus, a genus of more than twenty species of barklice known from eastern Asia. Most of these species were described by China by the almost ludicrously prolific psocopterologist… Continue reading Siniamphipsocus

Trichocaeciliinae

Belongs within: Pseudocaecilioidea. The Trichocaeciliinae are a group of barklice bearing an extensive covering of hair (Li 2002). Characters (Li 2002): Head and thorax covered with long hairs; leading edge of fore wing thickened, membranous part of fore wing covered with hairs, membranous part of hind wing covered with hairs or hairless except at tip; claws with… Continue reading Trichocaeciliinae

Nanopsocetae

Belongs within: Psocodea.Contains: Phthiraptera, Embidopsocinae, Liposcelis, Tapinella. The Nanopsocetae are a group of small booklice and barklice that lack wings or have wings with a reduced venation. Phylogenetic studies have indicated that the parasitic lice of the Phthiraptera have their ancestry within this group. They may be the sister group of the Liposcelididae, with which… Continue reading Nanopsocetae

Belongs within: Paraneoptera.Contains: Psocathropetae, Trogioidea, Lepidopsocidae, Psocomorpha, Nanopsocetae, Amphientometae. The Psocodea include the barklice, small insects that mostly feed on fungi and other micro-organisms, as well as the true parasitic lice. It is now generally accepted that the latter are a derived subgroup of the former. Free-living Psocodea have heads with a large, bulbous postclypeus… Continue reading Psocodea

Psocathropetae

Belongs within: Psocodea. The Psocathropetae are a group of barklice with a long head and long hind legs. Wings, if present, bear a nodulus, but brachypterous and micropterous forms are common in the family Psyllipsocidae (New & Lienhard 2007). Prionoglarididae have vein Sc in the fore wing long and joing R but this vein is… Continue reading Psocathropetae

Liposcelis

Belongs within: Nanopsocetae. Liposcelis, the booklice, is a cosmopolitan genus of minute flattened, wingless insects with a number of species being widely synanthropic. The genus is readily distinguised from related forms by the presence of a lateral protuberance on the hind femur (Mockford 1993). Liposcelis has been divided into a number of sections and groups… Continue reading Liposcelis

Trogioidea

Belongs within: Psocodea. The Trogioidea is a group of small barklice with wings reduced or absent. The majority of living species are included in the subfamily Trogiinae with the South American genus Anomocopeus sometimes treated as a distinct family. The Archaeatropidae and Empheriinae are known only from the fossil record. Within the Trogiidae, the genus… Continue reading Trogioidea

Myopsocinae

Belongs within: Psocetae. The Myopsocinae are a group of barklice of the Myopsocidae in which the hind wing has veins Rs and M fused for a length, and the outer edge of the fore wing is not curved (Li 2002). In the genus Smithersia, males bear a posterior U-shaped extension on the phallosome, and females… Continue reading Myopsocinae
