Cyriocosmus is a
genus of
tarantulas that was first described by
Eugène Louis Simon in 1903.[4] They are small to medium spiders, with a bicolored or one same color carapace.[5]
Diagnosis
It differs from all other
tarantulas by the paraembolic
apophysis in the
palpal bulbs of males, and a
spermatheca with two spiral receptacles, which usually end in a caliciform or globular extension. Except for
C. nogueiranetoi, which owns a S shape extension. All the species also own type 3
urticating hairs.[5]
Species
As of July 2022[update] it contains twenty-three species, found in South America, on
Tobago, and
Trinidad:[1]
