Chilelopsis calderoni

Chilelopsis calderoni is a species of mygalomorph spiders of Chile, named after Dr Raúl Calderón.[2] Males differ from C. puertoviejo in the more sinuous distal portion of the bulbal duct; females differ in the spermathecae with a distinct fundus and a narrowed duct. Males differ from C. serena by the presence of a dense patch of setae on the anterior tibiae, females in the undivided spermathecae.
