Subfamily Pseudomyrmecinae
Tetraponera rufonigra is another species in this family in South and Southeast Asia and appears to be one of the common causes of ant anaphylaxis along with Solenopsis geminata in Thailand.41 Pseudomyrmex ejectus (twig or oak ant) has a highly pharmacologically active venom and has given rise to multiple case reports of anaphylactic-type reactions.35
