Anyphaena fraterna
ghost spider
Anyphaena fraterna is a species of ghost spider in the family Anyphaenidae, first described by Banks in 1896. It belongs to a family of wandering hunters that do not build permanent webs for prey capture. The species is documented from the United States, though specific details about its ecology and behavior remain limited in published literature. Like other anyphaenids, it is presumably nocturnally active and associated with vegetation.
Anyphaena pectorosa
Eastern Spurred Ghost Spider
Anyphaena pectorosa is a species of ghost spider in the family Anyphaenidae, first described by L. Koch in 1866. It belongs to the pectorosa species group, one of five groups recognized within the North American and Mexican Anyphaena fauna. The species is distributed across the United States and Canada. As a member of Anyphaenidae, it is a wandering hunter rather than a web-builder.
Clubiona moesta
Clubiona moesta is a species of sac spider in the family Clubionidae, first described by Banks in 1896. It belongs to a family of wandering spiders that do not construct permanent webs for prey capture. The species has a documented distribution across North America and Asia, with records from the United States, Canada, and China. Like other sac spiders, it constructs temporary silken retreats for shelter rather than for prey capture.
Clubiona saltitans
Clubiona saltitans is a sac spider in the family Clubionidae, described by Emerton in 1919. The species name "saltitans" (Latin for "jumping" or "dancing") may allude to its active movement. Sac spiders in this genus are wandering hunters that construct silken retreats rather than prey-capture webs. They are primarily nocturnal predators of small insects and other arthropods. The genus Clubiona is distinguished from similar sac spiders by the presence of a distinct groove in the center of the carapace and a tuft of curved setae on the front edge of the abdomen.
Litopyllus
Litopyllus is a genus of ground spiders in the family Gnaphosidae, established by R. V. Chamberlin in 1922. The genus contains three described species: L. cubanus, L. realisticus, and L. temporarius. Members are classified as wandering hunters rather than web-builders.
Nodocion voluntarius
Nodocion voluntarius is a species of ground spider in the family Gnaphosidae, first described by Chamberlin in 1919. It belongs to a genus of small to medium-sized wandering spiders that actively hunt rather than build webs to capture prey. The species is documented from North America, though detailed ecological and behavioral studies remain limited. Like other gnaphosids, it likely occupies ground-level habitats and exhibits nocturnal activity patterns.
Sergiolus unimaculatus
Sergiolus unimaculatus is a ground spider in the family Gnaphosidae, first described by Emerton in 1915. Like other members of its genus, it is a nomadic, diurnal hunter that does not construct webs for prey capture. The species exhibits the characteristic bold coloration of Sergiolus, though specific pattern details for S. unimaculatus are less documented than for congeners such as S. capulatus. It is one of approximately sixteen Sergiolus species known from north of Mexico.
Trachelidae
Broad-Faced Sac Spiders, Ground Sac Spiders
Trachelidae is a family of araneomorph spiders within the RTA clade, elevated from subfamily status in 2014 based on molecular phylogenetic evidence. The family comprises 29 genera and approximately 307 species distributed across tropical, subtropical, and temperate regions worldwide. Members are commonly known as broad-faced sac spiders or ground sac spiders, though many species are arboreal. The family is characterized by reduced leg spines and other distinctive morphological synapomorphies that distinguish it from related families Corinnidae and Clubionidae.
