Remarks. S. guttipennis was originally described by Thomson (1868) with a female specimen from Buenos Aires, Argentina. This species has a widely distribution in South America ( Argentina, Bolivia, Chile, Colombia, Peru, Uruguay), and was redescribed by Couri (1982) based on male and female specimens.
