Chilelopsis puertoviejo explained
Chilelopsis puertoviejo is a species of mygalomorph spiders of Chile, named after its type locality: Puerto Viejo, Copiapó, Region III.[1] The species is most similar to C. calderoni, but differs in having the distal portion of the male bulbal duct less sinuous and the female spermathecae of uniform width, with no differentiated fundus. It differs from C. serena in the undivided female spermathecae and the male tibia I having a dense apical patch of setae.
