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
