Acanthogonatus alegre
Acanthogonatus alegre is a mygalomorph spider of Chile, its name using the Spanish word for “happy”, referring to the aspect of a happy face that the female epigastrium has in posterior view. Females are recognized by the epigastrium produced in a membranous extension and the long, slender and bifurcated spermathecae.
