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
[edit]The genus 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]
