Anyphaenidae is a family of araneomorph spiders, sometimes called anyphaenid sac spiders. They are distinguished from the sac spiders of the family Clubionidae and other spiders by having the abdominal spiracle placed one third to one half of the way anterior to the spinnerets toward the epigastric furrow on the underside of the abdomen. In most spiders the spiracle is just anterior to the spinnerets. Like clubionids, anyphaenids have eight eyes arranged in two rows, conical anterior spinnerets and are wandering predators that build silken retreats, or sacs, usually on plant terminals, between leaves, under bark or under rocks. There are more than 500 species in over 50 genera worldwide.
Dictynidae is a family of cribellate, hackled band-producing spiders first described by Octavius Pickard-Cambridge in 1871. Most build irregular webs on or near the ground, creating a tangle of silken fibers among several branches or stems of one plant.
Corythalia is a genus of jumping spiders that was first described by Carl Ludwig Koch in 1850.
Phiale is a genus of jumping spiders that was first described by Carl Ludwig Koch in 1846. P. albovittata has been considered a junior synonym of Freya perelegans since 2006.
Huttonia is a monotypic genus of ecribellate South Pacific araneomorph spiders in the Huttoniidae family containing the single species, Huttonia palpimanoides. Although only one species is described, there are still about twenty more undescribed species.
Zygiella is a genus of orb-weaver spiders first described by F. O. Pickard-Cambridge in 1902. In 2015, Parazygiella was determined to be a taxonomic synonym of Zygiella, and its species were moved to Zygiella.
Aphantochilus is a genus of ant-mimicking crab spiders that was first described by Octavius Pickard-Cambridge in 1871. As of June 2020 it contains three species, found in Paraguay, Brazil, Argentina, and Panama: A. cambridgei, A. inermipes, and A. rogersi. It is a senior synonym of Cryptoceroides.
Chorizopes is a genus of orb-weaver spiders first described by O. Pickard-Cambridge in 1871. Though it belongs to the orb weaver family, these spiders move through leaf litter preying on other spiders rather than spinning webs. The original name was "Chorizoopes", but the emendation Chorizopes by Tamerlan Thorell is now protected by usage.
Coneweb spiders (Diguetidae) are six-eyed haplogyne spiders that live in tangled space webs, fashioning a cone-like central retreat where they hide and lay eggs. It is a small family, containing only two genera with fifteen species and is confined to the New World, preferring deserts. Members of the genus Diguetia usually build their webs in shrubs or between cactus pads. They have the same eye arrangement as the venomous recluse spiders, but none are known to be harmful to humans.
Brachypelma albiceps is a species of spider in the tarantula family, Theraphosidae. It is known as the Mexican golden red rump tarantula or the Amula red rump tarantula. The carapace is a light golden color and the abdomen dark, covered with long red hairs. Females typically live for about 15 years. Males usually live about 5 years or up to 12 months after the last molt.
Stenochilus is a genus of Asian araneomorph spiders in the Stenochilidae family, and was first described by Octavius Pickard-Cambridge in 1871. As of September 2019 it contains three species, found in Asia: S. crocatus, S. hobsoni, and S. scutulatus. It is considered a senior synonym of Metronax
Robertus is a genus of comb-footed spiders that was first described by Octavius Pickard-Cambridge in 1879. It is considered a senior synonym of Garritus.
Schenkeliella is a monotypic genus of Sri Lankan long-jawed orb-weavers containing the single species, Schenkeliella spinosa. The species was first described by Octavius Pickard-Cambridge in 1871 under the name Oeta spinosa, but it was renamed to "Schenkeliella" by Embrik Strand in 1934 because the name was already in use for a genus of ermine moths. Originally placed with the Nesticidae, it transferred to the Tetragnathidae in 1980.
Cephalobares is a genus of Asian comb-footed spiders that was first described by Octavius Pickard-Cambridge in 1871. As of May 2020 it contains two species, found in Asia: C. globiceps and C. yangdingi.
Porrhomma is a genus of sheet weavers that was first described by Eugène Louis Simon in 1884.
Sphecozone is a genus of sheet weavers that was first described by Octavius Pickard-Cambridge in 1871.
Stephanopis is a genus of crab spiders first described by Octavius Pickard-Cambridge in 1869. The genus Stephanopis was erected for five newly described species, including S. altifrons, from Australia. Stephanopis was characterized by the high cephalic region with unequally sized anterior eyes disposed in a strongly recurved row, opisthosoma ending in several spiniform projections and dorsoventrally depressed habitus. According to Pickard-Cambridge, the single specimen used for the description of S. altifrons was dry-pinned. Therefore the specimen could not be properly examined, so it was not possible to determine if the specimen was adult. Moreover, he states his own sketch of the spider as “hasty”. This may explain why the somatic characters were inadequately described, genitalic features were not mentioned at all, and the illustrations were not detailed enough, making the species unidentifiable.
Collinsia is a genus of dwarf spiders that was first described by Octavius Pickard-Cambridge in 1913.
Tliltocatl verdezi is a species of spiders in the family Theraphosidae (tarantulas), found in Mexico.
