About Money Spider:
- Researchers of Christ College, Irinjalakuda, Thrissur, have discovered the spider that belongs to the family of dwarf spiders (Linyphiidae) under the genus Prosoponoides.
- It has been given the name Prosoponoides biflectogynus.
- Only six species of spiders belonging to this genus have been identified from across the world so far.
- It is the first report of this genus from India and hence no extensive studies have been conducted on this species of spiders in the country.
- Physical features:
- The male and the female money spiders are typically 3 mm and 4 mm long
- Both sexes are dark brown and have irregular silver patches and black spots on elliptical abdomen.
- There are numerous fine black spines on their olive green legs.

- They belong to the family of Salticidae.
- The ant-mimicking spider has been named Toxeus alboclavus.
- They perfectly mimic ants by lifting their front pair of legs while walking as a mechanism to escape from potential predators.
- Only three species of this genus have been reported from India, and this is the first species reported from the Western Ghats.
- Physical Features:
- The male and the female spiders of this species grow up to 4 mm and 6 mm long
- A pair of white stripes on the dark brown abdomen of females makes them distinct from other spiders of this group.
