Parasteatoda

Parasteatoda is a genus of comb-footed spiders that was first described by Allan Frost Archer in 1946.^[2] The name is a combination of the Ancient Greek "para-" (παρά), meaning "near" or "next to", and the theridiid genus Steatoda. The Japanese name for this genus is O-himogumo zoku ("thread silk spider family").^[3]

Description

The eye arrangement of spiders in the genus Parasteatoda

Parasteatoda species have a characteristic teardrop-shaped abdomen, with the anterior section much higher than the carapace and the spinnerets pointed downwards. The abdomen's colouration is highly variable, both between and often within species. They have slight sexual dimorphism; males are visually similar to females, although slightly smaller.^[4]

Species

It is mostly an Old World genus, with many species found in Asia and New Guinea, though the distribution reaches into Europe. A few species originate from the New World, but many have been introduced, and they are becoming more widespread in the Americas and Europe.^[3]

As of May 2020 it contains forty-two species and two subspecies:^[1]
