A pseudoscorpion, also known as a false scorpion or book scorpion, is an arachnid belonging to the order Pseudoscorpiones, also known as Pseudoscorpionida or Chelonethida.
Ground spiders comprise Gnaphosidae, the seventh largest spider family with nearly 2,000 described species in over 100 genera distributed worldwide. There are 105 species known to central Europe, and common genera include Gnaphosa, Drassodes, Micaria, Cesonia, Zelotes and many others. They are closely related to Clubionidae. At present, no ground spiders are known to be seriously venomous to humans.
Pellolessertia is a monotypic genus of African jumping spiders containing the single species, Pellolessertia castanea. It was first described in 1927, and is only found in Africa. Dippenaar-Schoeman & Jocqué gave the distribution range as Zad're to Ethiopia.
Ctenolepisma is a genus of primitive insects in the order Zygentoma, closely related to the silverfish and firebrat but less reliant on human habitation, some species being found both indoors and outdoors and some found exclusively outdoors. The genus is distributed nearly worldwide in warm regions. Australia lacks native Ctenolepisma, but is home to introduced species.
The Chthonioidea are a superfamily of pseudoscorpions, representing the earliest diverging and most primitive living pseudoscorpions. The superfamily contains two families.
Trematochromis benthicola is a ray-finned fish species in the cichlid family (Cichlidae), subfamily Pseudocrenilabrinae and the tribe Haplochromini. It is found throughout Lake Tanganyika in the Burundian, the Democratic Republic of the Congo, Tanzanian, and Zambian shoreline. Its preferred habitat are the hidden recesses of caves in shallow water.
Thomandersia is the sole genus in the Thomandersiaceae, an African family of flowering plants. Thomandersia is a genus of shrubs and small trees, with six species native to Central and West Africa.
The Sternophoridae are a family of pseudoscorpions with about 20 described species in three genera. While Afrosternophorus is an Old World genus, found mainly in Australasia, the other two genera are found in the New World, from El Salvador to the southern USA and in the Dominican Republic.
The Menthidae are a small family of pseudoscorpions that are nevertheless spread around the world. While Menthus is found from Mexico to California, Oligomenthus lives in South America. The monotypic genera Paramenthus and Thenmus live in Israel and Australia, respectively.
Chthoniidae is a family of pseudoscorpions within the superfamily Chthonioidea. The family contains more than 600 species in about 30 genera. Fossil species are known from Baltic, Dominican, and Burmese amber. Chthoniidae now includes the former families Tridenchthoniidae, and Lechytiidae which has been demoted to subfamilies.
Laemophloeidae, "lined flat bark beetles," is a family in the superfamily Cucujoidea characterized by predominantly dorso-ventrally compressed bodies, head and pronotal discs bordered by ridges or grooves, and inverted male genitalia. Size range of adults is 1–5 mm (0.04–0.2 in) in length. Currently, it contains 40 genera and about 450 species, and is represented on all continents except Antarctica; species richness is greatest in the tropics.
Chalybion is a genus of blue mud dauber wasps in the family Sphecidae. Chalybion species nest in a wide range of natural and artificial cavities such as holes in wood, walls, plant stems, etc., where they typically provision their brood cells with paralyzed spiders. They also reuse old nests of other wasps like Trypoxylon and Sceliphron.
Gallagher's free-tailed bat is a free-tailed bat endemic to the Democratic Republic of the Congo. Only one individual has ever been documented.
Copelatus congo is a species of diving beetle. It is part of the genus Copelatus in the subfamily Copelatinae of the family Dytiscidae. It was described by Gschwendtner in 1938.
Craterispermum is a genus of flowering plants in the family Rubiaceae. It contains 16 species that occur in tropical Africa and Seychelles. It is the only genus in the tribe Craterispermeae, of which the divergence time is estimated at 34.8 million years ago.
Termitotroginae is a monotypic subfamily of the family Scarabaeidae, the scarab beetles. The only genus in the subfamily is Termititrox. A second genus, Aphodiocopris, Arrow, 1920, has been synonymised with Termitotrox. All known members of this subfamily are tiny, blind and flightless, and dwell within the fungal gardens of colonies of species of termite in Africa or tropical Asia.
Atemnidae is a family of pseudoscorpions.
Homapoderus tamsi is a species of weevils of the family Attelabidae. It occurs in Equatorial Guinea, the Democratic Republic of the Congo and the island of Príncipe in São Tomé and Príncipe. The species was described as Parapoderus tamsi in 1937. It was placed into the genus Homapoderus by Legalov in the mid-2000s.
