Dysdera can be distinguished from young miturgids of the genus Tecution (which also have reddish coloration and large fangs) by the six eyes (Tecution species have eight widely spaced eyes). There is a possibility of confusion of young individuals with young prodidomids, which may be elongate and sometimes appear to have only 6 eyes (Ashmole & Ashmole 2004).
