83-85, $ 8. 
Note. Mello-Leitao (1939) figure 31 is printed upside down; 
if it had been turned around the synonymy with the common S. grossa 
would have been recognized earlier. Steatoda grossa females can be 
confused with females of S. andina. Only details of the posterior 
rim of the epigynum seem to separate females of the two species. The 
male palpi, however, are very different. 
Natural History. The species has been collected in subtropical rain 
forests in Oxapampa, and under stones on guano islands. 
Distribution. Cosmopolitan; along coast of United States, Mexico, 
South America.
