英语百科

Mygalomorphae

Chelicerae of a black wishbone spider (Nemesiidae)
Sphodros rufipes, an atypical mygyalomorph

The Mygalomorphae or mygalomorphs are an infraorder of spiders. The name is derived from the Greek mugalē, meaning "shrew", plus morphē meaning form or shape. An older name for the group is Orthognatha, derived from the orientation of the fangs which point straight down and do not cross each other (as they do in the araneomorphs).
