Belaphotroctes
Belaphotroctes is a genus of small psocids (barklice and booklice) in the family Liposcelididae. Members of this genus are minute, dorsoventrally flattened insects adapted to living in concealed microhabitats such as leaf litter, bark crevices, and stored products. The genus was established by Roesler in 1943 and has been recorded from both the New World (USA, Mexico, Jamaica) and Africa (Angola, Togo).
Lachesilla pacifica
Lachesilla pacifica is a species of barklouse in the family Lachesillidae, first described by Chapman in 1930. It belongs to the order Psocodea, a group of small, soft-bodied insects commonly known as psocids or booklice. The species has been recorded across a broad geographic range spanning North America, Europe, and parts of Middle America.
Lachesilla sulcata
fateful barklouse
Lachesilla sulcata is a species of barklouse described by García-Aldrete in 1986. It belongs to the family Lachesillidae, a group of small, soft-bodied insects commonly known as barklice or booklice. The species has been documented in both Central America and North America, with confirmed records from Mexico and the United States. As with many psocid species, detailed ecological and behavioral information remains limited.
Lepinotus inquilinus
granary booklouse
Lepinotus inquilinus is a species of granary booklouse in the family Trogiidae. It has a broad cosmopolitan distribution spanning Africa, Australia, Europe, Northern Asia (excluding China), Central America, North America, Oceania, and Southern Asia. The species has been documented in the Azores archipelago (Pico, São Miguel, and Terceira islands). As a member of the granary booklice group, it is associated with stored products and human-modified environments.
Leptoglossus
leaf-footed bugs
Leptoglossus is a genus of true bugs in the leaf-footed bug family Coreidae, tribe Anisoscelini. Species are characterized by leaflike dilations of the hind tibia, a diagnostic trait of the genus. The genus is distributed throughout the Americas, with some introduced populations in Europe and Asia. Several species are economically significant agricultural pests, notably L. occidentalis, which has become invasive in multiple continents.

decolor
booklouse
Liposcelis decolor is a minute stored-product pest psocid (booklouse) of significant economic importance worldwide. It infests stored grains and grain products, causing direct damage through consumption of endosperm and germ, and indirect damage by distributing molds and transmitting disease pathogens. The species exhibits high tolerance to phosphine fumigant, making chemical control difficult, and recovers rapidly from poorly conducted fumigations. It has been extensively studied as prey for biological control agents including the warehouse pirate bug Xylocoris flavipes and predatory mites Cheyletus eruditus and C. malaccensis.
Liposcelis entomophila
booklouse
Liposcelis entomophila is a small psocid species commonly known as a booklouse. It is a significant pest of stored grain products, with documented infestations in wheat and other stored foods. The species exhibits sexual dimorphism in development, with females passing through four nymphal stages and males through three. It has developed notable resistance to phosphine fumigants used in grain storage, with resistant factors of 40- to 80-fold reported in Chinese populations. The species has a broad global distribution spanning six continents.
Liposcelis hirsutoides
booklouse
Liposcelis hirsutoides is a species of booklouse in the family Liposcelididae. It was described by Mockford in 1978. The species has been documented across a broad geographic range spanning North, Central, and South America. Like other members of the genus Liposcelis, it belongs to the order Psocodea, which includes barklice and parasitic lice.
Liposcelis nigra
booklouse
Liposcelis nigra is a minute species of booklouse in the family Liposcelididae. It belongs to a genus of nearly microscopic insects commonly associated with stored products and household environments. The species was described by Nathan Banks in 1900 and is known from North America.
Liposcelis ornata
booklouse
Liposcelis ornata is a species of booklouse described by Mockford in 1978. It belongs to the family Liposcelididae, a group of small, wingless or weakly winged insects commonly associated with stored products and human habitats. The species has been documented across a broad geographic range spanning Central America, North America, and South America.
Liposcelis pearmani
Liposcelis pearmani is a species of booklouse in the family Liposcelididae, described by Lienhard in 1990. It belongs to a genus of small, wingless insects commonly associated with stored products and human dwellings. Like other Liposcelis species, it is likely a pantry pest, though specific details about this particular species are limited in available sources.
Soa flaviterminata
Soa flaviterminata is a species of booklouse in the family Lepidopsocidae, described by Enderlein in 1906. It belongs to the order Psocodea, a group of small, often overlooked insects that includes both parasitic lice and free-living barklice and booklice. The species is placed in the suborder Trogiomorpha, a lineage characterized by reduced wing venation and other derived features. Like other members of its family, it likely inhabits sheltered microhabitats in tropical or subtropical environments.
Sphaeropsocus bicolor
Sphaeropsocus bicolor is a species of booklouse in the family Sphaeropsocidae, described by Mockford in 2013. It belongs to the order Psocodea, a group of small, soft-bodied insects commonly known as barklice and booklice. The genus Sphaeropsocus is part of a family characterized by distinctive morphological features, though specific ecological details for this species remain limited. Only a single observation has been recorded in public databases.
