Guides
Alcimosphenus
Alcimosphenus is a genus of long-jawed orb-weaver spiders in the family Tetragnathidae, established by Eugène Simon in 1895. The genus is currently considered doubtful in status, with its taxonomic validity questioned in modern arachnological literature. It is poorly known, with limited published information on its constituent species, biology, or diagnostic characteristics. Most records of this genus are historical, and its species may require taxonomic revision.
Azilia affinis
Azilia affinis is a species of long-jawed orb-weaver spider in the family Tetragnathidae. It was described by O. Pickard-Cambridge in 1893. The species occurs from the southern United States through Central America to Panama. Like other members of Tetragnathidae, it possesses elongated chelicerae (jaws) adapted for capturing prey while building orb-shaped webs.
Glenognatha foxi
Dwarf Ground Long-jawed Spider
Glenognatha foxi is a species of long-jawed orb weaver spider in the family Tetragnathidae, commonly known as the Dwarf Ground Long-jawed Spider. It is distributed across a broad latitudinal range from Canada to Panama. The species belongs to a genus of small-bodied spiders characterized by elongated chelicerae and ground-dwelling habits, distinguishing them from the more web-associated Tetragnatha.
Pachygnatha autumnalis
Big-eyed Thick-jawed Spider
Pachygnatha autumnalis is a long-jawed orb-weaver spider in the family Tetragnathidae, first described by Marx in 1884. The species occurs across a broad North American and Caribbean range, including the United States, Canada, and Cuba. As a member of the genus Pachygnatha, it shares the characteristic robust, enlarged chelicerae that distinguish this group from other tetragnathids. Observations suggest it is primarily active during autumn months, consistent with its specific epithet.
Pachygnatha furcillata
Pachygnatha furcillata is a species of long-jawed orb weaver spider in the family Tetragnathidae. It is known from the United States, though specific details about its biology and ecology remain poorly documented. Like other members of its genus, it possesses elongated chelicerae (jaws) characteristic of long-jawed orb weavers.
Tetragnatha straminea
long-jawed orb weaver
Tetragnatha straminea is a species of long-jawed orb weaver spider in the family Tetragnathidae. It is found across northern North America, including the United States, Canada, and Cuba. Like other members of the genus Tetragnatha, it possesses elongated chelicerae and a slender body adapted for camouflage. The species was described by Emerton in 1884.
Tetragnatha viridis
Green Long-jawed Orbweaver
Tetragnatha viridis is a species of long-jawed orb-weaver spider in the family Tetragnathidae, distinguished by its striking emerald green coloration. It is found in the eastern United States and adjacent southern Canada, with recent records documenting its presence in Quebec, Canada. Like other members of its genus, it constructs horizontal orb webs and possesses characteristically elongated chelicerae and slender body proportions.
