Trachelas tranquillus, the broad-faced sac spider, is a species of true spider in the family Trachelidae. It is found in the United States and Canada. [1] [2] [3] [4]
Huntsman spiders, members of the family Sparassidae, are known by this name because of their speed and mode of hunting. They are also called giant crab spiders because of their size and appearance. Larger species sometimes are referred to as wood spiders, because of their preference for woody places. In southern Africa the genus Palystes are known as rain spiders or lizard-eating spiders. Commonly, they are confused with baboon spiders from the Mygalomorphae infraorder, which are not closely related.
The Araneomorphae are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action, in contrast to the Mygalomorphae, where they point straight down. Araneomorphs comprise the vast majority of living spiders.
Dysderidae, also known as woodlouse hunters, sowbug-eating spiders, and cell spiders, is a family of araneomorph spiders first described by Carl Ludwig Koch in 1837. They are found primarily in Eurasia, extending into North Africa with very few species occurring in South America. Dysdera crocata is introduced into many regions of the world.
The Pholcidae are a family of araneomorph spiders. The family contains more than 1,800 individual species of pholcids, including those commonly known as cellar spider, daddy long-legs spider, carpenter spider, daddy long-legger, vibrating spider, gyrating spider, long daddy, skull spider, and angel spider. The family, first described by Carl Ludwig Koch in 1850, is divided into 94 genera.
Crevice weaver spiders (Filistatidae) comprise cribellate spiders with features that have been regarded as "primitive" for araneomorph spiders. They are weavers of funnel or tube webs. The family contains 18 genera and more than 120 described species worldwide.
Psechridae is a family of araneomorph spiders with about 70 species in two genera. These are among the biggest cribellate spiders with body lengths up to 2 centimetres (0.79 in) and funnel webs more than 1 metre in diameter.
Diguetia is a genus of coneweb spiders that was first described by Eugène Simon in 1895. Members of this genus are six-eyed spiders that are either white or patterned. They are common in the southwestern United States and Mexico, and one species is found in Argentina. In the United States, species have been found in Arizona, California, Nevada, New Mexico, and Texas. These spiders build a tubular retreat at the tip of their tent-like webs. Once an insect is caught in the web, the spider bites it and injects venom to stop its prey from moving, later wrapping it in silk. Both males and females use stridulation while mating, with females also stridulating when harassed. Two species of jumping spiders feed on its eggs. There are eleven Diguetia species.
Trachelas oreophilus is a species of spiders of the genus Trachelas. It is native to India and Sri Lanka.
Trachelas quisquiliarum, is a species of spider of the genus Trachelas. It is endemic to Sri Lanka.

Trachelas is a genus of araneomorph spiders which has variously been placed in families Trachelidae or Corinnidae. Current taxonomy places it in Trachelidae.
Habronattus conjunctus is a species of jumping spider in the family Salticidae. It is found in the United States and Mexico.
Acanthepeira stellata, known generally as the starbellied orbweaver or starbellied spider, is a species of orb weaver in the spider family Araneidae. It is found in a range from Canada to Mexico. It is most commonly found along the Eastern and Western coastline of North America.
Philodromus marxi, the metallic crab spider, is a species of running crab spider in the family Philodromidae. It is found in the United States. It is a sexually dimorphic species. The males are smooth with a metallic sheen and the females are bristly white and grey.
Mastophora phrynosoma is a species of orb weaver in the spider family Araneidae. It is found in the United States. Like all known species of the genus Mastophora, adult females are bolas spiders, capturing their prey with one or more sticky drops at the end of a single line of silk rather than in a web. Males and juvenile females capture their prey directly with their legs.
Scytodes fusca, the brown spitting spider, is a species of spitting spider in the family Scytodidae. It is found in Central and Southern America, has been introduced into Europe, tropical Africa, Seychelles, Myanmar, China, Japan, and Hawaii.
Phidippus comatus is a species of jumping spider in the family Salticidae. It is found in North America.
Trachelas volutus is a species of true spider in the family Trachelidae. It is found in the United States and Mexico.
Habronattus tranquillus is a species of jumping spider in the family Salticidae. It is found in the United States and Mexico.
Paratrachelas is a genus of araneomorph spiders in the family Trachelidae, first described by M. M. Kovblyuk & A. A. Nadolny in 2009.
