Latrodectinae

The medically important widow spiders and redbacks(Latrodectus) combine with Steatoda and Crustulina to form the Latrodectinate group. It is of interest that the only theridiids outside Latrodectus known to be potently venomous to vertebrates are Steatoda paykulliana and S. nobilis. Other Steatoda and Crustulina species may be found to be similarly venomous.
