Guides
Theridula gonygaster
Ladybird Spider
Theridula gonygaster is a species of cobweb spider in the family Theridiidae. Commonly known as the Ladybird Spider, it has a broad native range across Central and South America and the Caribbean, and has been introduced to multiple regions including parts of Europe, Africa, and Asia. The species is notable for its widespread anthropogenic dispersal and distinctive appearance.
Thymoites camano
cobweb spider
Thymoites camano is a species of cobweb spider in the family Theridiidae, first described by Levi in 1957. It is known only from the United States. As a member of Theridiidae, it constructs irregular, three-dimensional webs to capture prey. The species remains poorly documented in scientific literature.
Thymoites minero
Thymoites minero is a species of cobweb spider in the family Theridiidae, first described by Vincent D. Roth in 1992. The species is known from the United States and is part of a genus of small theridiid spiders. Like other members of Theridiidae, it constructs irregular, three-dimensional webs rather than the flat orb webs characteristic of many other spider families. The genus Thymoites contains numerous species, many of which are poorly known and difficult to distinguish without close examination.
Thymoites pallidus
Thymoites pallidus is a species of comb-footed spider in the family Theridiidae, first described by Emerton in 1913. This species is known from Cuba, the United States, and the Caribbean region extending to Venezuela. Like other theridiid spiders, it possesses the characteristic comb-like serrated bristles (setae) on the tarsi of the hind legs used for manipulating silk. The species epithet 'pallidus' refers to its pale coloration.
Tidarren sisyphoides
Tent Cobweb Weaver
Tidarren sisyphoides is a tangle web spider (family Theridiidae) known for extreme sexual size dimorphism, with males approximately 10% the size of females. The species exhibits a rare mating system in which males die during copulation and remain attached to females for over two hours, though females do not practice sexual cannibalism. It constructs a distinctive three-dimensional web with a dome-shaped sheet and upper tangle that functions as the primary prey capture structure.
Wamba crispulus
Wamba crispulus is a species of cobweb spider in the family Theridiidae, originally described as Theridion crispulum by Eugène Simon in 1895. The species has an exceptionally broad distribution spanning the Americas from Canada to Brazil and throughout the Caribbean. It belongs to the genus Wamba, which contains relatively few described species.
Yunohamella
Yunohamella is a genus of comb-footed spiders in the family Theridiidae, established by H. Yoshida in 2007. The genus is characterized by distinct male genital morphology: a large tegulum, small median apophysis, thin embolus, and distinct tegular apophysis. Females have an epigyne lacking a pointed scapus or possessing a blunt scapus. As of 2026, the genus comprises thirteen species distributed across Asia, Europe, and North America. Recent taxonomic revisions have clarified species boundaries using morphological and molecular data, including the reestablishment of Y. mneon as a valid species and the synonymy of Y. varietas.
Yunohamella lyrica
Lyric Cobweaver
Yunohamella lyrica is a cobweb spider in the family Theridiidae, commonly known as the Lyric Cobweaver. The species has a broad geographic distribution spanning North America and East Asia, including Korea and Japan. It belongs to a genus of small spiders that construct irregular, tangled webs.
