Chilelopsis calderoni explained
Chilelopsis calderoni is a species of mygalomorph spiders of Chile, named after Dr Raúl Calderón.[1] 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.
